Best Air Tank For Trailer: Compare 9 Brake and Utility Tanks

#1 · Best Overall

1. Mytee Products Air Tank

• Weight: 20 lb

Best for: Freightliner replacement tank.

Why it ranks #1: Lists a 1490-cu.-in. capacity and replacement references including 19840M1D and HDX 19840, making it a targeted Freightliner brake-tank option.

A 1,490-cubic-inch reservoir with a 2-3/4-inch mounting port gives this Mytee tank a defined replacement role for compatible Freightliner air-brake setups. Its listed OEM references include HDX 19840 and 19840M1D, helping buyers identify the intended parts match before planning a trailer repair.

The 9.5-by-27.5-inch size and 2-3/4-inch mounting port provide concrete dimensions to compare with the existing installation, while the 1,490-cubic-inch capacity identifies its reservoir volume. Mytee lists HDX 19840, HDX19840, 172.200, 19840, and 19840M1D as replacement references, giving parts shoppers several ways to check the intended application. The product is described as a Freightliner air-brake tank, so its strongest fit is a matching replacement rather than a general-purpose air supply.

Skip it if you need the listed Peterbilt 08-02347 replacement application; the Mytee Products twin-chamber tank specifies that fit instead.

For a trailer owner replacing a compatible Freightliner air-brake reservoir, the specified capacity, dimensions, and OEM references make application checking straightforward. Match the existing mounting arrangement and listed replacement numbers before choosing it.

#2 · Best Trailer-Specific

2. Hoosier 95156 Air Tank

• Weight: 5 lb

Best for: Four-port trailer tank.

Why it ranks #2: Explicitly fashioned for trailer applications, with four ports, 9-1/2-inch diameter, and 27-1/2-inch center-to-center measurement.

Four ports paired with a 27-1/2-inch center-to-center measurement make the Hoosier 95156 especially identifiable for trailer air-tank replacement planning. Its 9-1/2-inch size and three-stage pretreatment, rated for 504 hours of salt-spray resistance, add useful fit and corrosion-protection details.

The four-port layout and 27-1/2-inch center-to-center measurement help buyers compare connection and mounting positions with an existing trailer setup. Hoosier’s three-stage pretreatment is listed with 504 hours of salt-spray resistance, a relevant protection detail for equipment exposed to road conditions. The steel construction and paint finish add further wear and corrosion protection, while the pressure switch controls the automatic valve. Those features make the tank’s connections and maintenance context clearer before installation.

Skip it if you need a two-port, 12-inch-diameter Hoosier tank; the Belgrade Hoosier HOS1242 matches those listed specifications.

A trailer operator seeking a steel Hoosier tank with four ports and documented salt-spray resistance can use these details to compare an existing installation. Verify that the 27-1/2-inch center spacing fits the mounting layout.

#3 · Best Genuine Replacement

3. Great Dane HOS1205 Air Tank

Best for: Genuine Great Dane replacement.

Why it ranks #3: A genuine Great Dane Trailers air tank with alloy steel and stainless steel listed, suiting buyers seeking the trailer maker’s specified part.

The genuine Great Dane HOS1205 air tank provides a clearly identified manufacturer part for buyers sourcing a replacement on a compatible trailer. Its alloy-steel and stainless-steel material listing gives useful construction information, while the named model helps narrow parts identification to this specific tank.

Great Dane identifies this as a genuine air tank, and model number HOS1205 gives a direct reference for parts inquiries or replacement planning. The listed alloy-steel and stainless-steel materials provide a construction detail for buyers comparing the part with their existing equipment. Because the supplied information does not specify tank capacity, dimensions, or port arrangement, installation planning should rely on matching the HOS1205 identity rather than assuming a particular layout or volume.

Skip it if you need a listed 2,850-cubic-inch capacity and dual main ports; the Velvac 035107 specifies both details.

This is best for a buyer who has identified Great Dane HOS1205 as the needed trailer air tank and can match the part number. Check the existing tank’s layout because dimensions and port details are not supplied here.

#4 · Best Two-Port Option

4. Hoosier HOS1242 Air Tank

• Weight: 5 lb

Best for: Two-port Hoosier replacement.

Why it ranks #4: Trailer-oriented Hoosier tank with a 12-inch diameter and two ports, useful when those dimensions and connection count match the existing installation.

The Hoosier HOS1242 pairs a 12-inch diameter with a two-port layout, giving trailer owners two useful identifiers when matching an existing air tank. Its three-stage pretreatment is rated for 504 hours of salt-spray resistance, adding a concrete corrosion-protection specification to the fit check.

The stated 12-inch diameter and two ports help distinguish this HOS1242 from tanks with different connection layouts, while the listed 30-inch length offers another dimension for installation comparison. Its steel construction and paint finish are described as supporting durability and resistance to wear and corrosion. Hoosier also specifies a pressure switch that controls the automatic valve, and three-stage pretreatment with 504 hours of salt-spray resistance provides a useful protection detail for trailer service conditions.

Skip it if you need four ports and 27-1/2-inch center-to-center spacing; the Belgrade Hoosier 95156 lists those specifications.

This suits a trailer owner matching a 12-inch Hoosier tank with two ports and seeking specified corrosion protection. Compare the listed length and connection arrangement with the current installation, since the port count is specific.

#5

5. Mytee Products Twin Chamber Tank

• Weight: 25.8 lb

Best for: Peterbilt twin-chamber replacement.

Why it ranks #5: Provides 2267 cu. in. in a twin-chamber design with seven NPT ports and Peterbilt replacement references, though fitment is application-specific.

A 2,267-cubic-inch capacity and twin-chamber construction give this Mytee air-brake tank substantial specified reservoir volume for compatible Peterbilt applications. Its seven NPT-threaded ports, including three main ports, make the connection layout a key part of identifying whether it fits a trailer’s existing brake and suspension system.

The 2,267-cubic-inch volume is intended to provide a compressed-air reservoir for consistent pressure in braking and suspension functions. Seven NPT-threaded ports, split into three main ports and four end ports, give buyers concrete connection details to compare during replacement planning. The listed Peterbilt references include 08-01276, 08-02347, and 802347, along with Automann 172.2347. Its 9.5-inch maximum diameter and 32-inch length help assess space, while the alloy-steel construction identifies its material.

Skip it if you need a Fontaine Revolution trailer tank; the ILoca Fontaine 51475410 is listed for late-model Revolution flatbeds.

Choose this for a compatible Peterbilt trailer replacement where twin chambers, the stated port arrangement, and 2,267-cubic-inch capacity suit the system. Confirm the 32-inch length and OEM references against the tank being replaced.

6. Fontaine 51475410 Air Tank

Best for: Fontaine Revolution trailer fit.

Why it ranks #6: An aluminum tank identified for late-model Fontaine Revolution flatbed trailers, with a 12-inch body diameter and 30.5-inch overall length.

Compatibility with late-model Fontaine Revolution flatbed trailers is the defining detail of this aluminum air tank, giving owners of those trailers a focused replacement reference. Its 12-inch tank body and 30.5-inch overall length supply practical dimensions for checking available space before installation.

The Fontaine 51475410 is identified as an aluminum air tank used on late-model Fontaine Revolution flatbed trailers, so its clearest application is a matching trailer rather than a general replacement. The 12-inch diameter and 26.5-inch tank body length help compare the main vessel with available space, while the 30.5-inch overall length accounts for the full listed assembly dimension. ILoca Services is identified as an authorized Fontaine Trailer Dealer, supporting parts sourcing for buyers checking this specific model.

Skip it if you need a 4-gallon tank rated to 200 PSI with seven ports; the Vixen Air VXT4100 lists those specifications.

This is a focused option for owners maintaining a late-model Fontaine Revolution flatbed who can match part 51475410. Compare the 12-inch body and 30.5-inch overall length with the available trailer space.

#7 · Highest Listed Capacity

7. Velvac 035107 Air Tank

• Weight: 34.6 lb

Best for: High-capacity air-brake reservoir.

Why it ranks #7: Its 2850-cu.-in. capacity and dual main ports stand out, but the listing gives no specific trailer model compatibility.

The Velvac 035107’s 2,850-cubic-inch capacity gives trailer owners a clearly specified air-brake reservoir volume, paired with a 12-by-27-inch tank and dual main ports. Flange mounting and all-steel construction further identify the installation style and material for replacement planning.

A 2,850-cubic-inch capacity provides the central sizing detail for buyers matching an air-brake reservoir, while the dual main ports and flange mounting help compare its connection and attachment arrangement with the current tank. The 12-by-27-inch dimensions support space checks. Velvac states the tank is water tested before shipping, internally corrosion resistant, and dipped for rust resistance with primer sealing; its SAE J10 compliance is another listed specification for parts evaluation.

Skip it if you need a seven-port tank with mounting hardware included; the Vixen Air VXT4100 lists that configuration.

A trailer owner replacing an air-brake reservoir can use its capacity, flange mounting, and dual main ports to assess fit. Account for the 34.6-pound listed weight when planning handling and installation.

#8

8. Vixen Air VXT4100 Tank

• Weight: 15 lb

Best for: Compact seven-port air supply.

Why it ranks #8: A 4-gallon, seven-port steel tank rated to 200 PSI, but listed for air suspension and related uses rather than a specific trailer brake fit.

A 4-gallon capacity, seven ports, and a 200 PSI rating make the Vixen Air VXT4100 a versatile compact air-supply option for trailer-related pneumatic setups. The steel tank measures 24 inches long and 7 inches in diameter, and the kit includes mounting hardware to support installation planning.

Seven ports give this tank multiple connection points for air-suspension, air-ride, air-spring, or train-horn setups, while its 200 PSI maximum pressure provides a defined operating limit. The 4-gallon capacity establishes the available reservoir volume, and precision-welded alloy steel with an anti-corrosion film specifies its construction and surface protection. At 24 by 7 by 8.75 inches, it offers dimensions to compare against the mounting space; included mounting hardware is part of the kit.

Skip it if you need a tank with 2,850 cubic inches and dual main ports; the Velvac 035107 lists both for air-brake use.

This fits buyers needing a seven-port tank for air suspension, air springs, or another listed pneumatic use, with mounting hardware included. Check its 4-gallon capacity, 200 PSI limit, and dimensions against the trailer system.

#9

9. VIAIR 91028 Air Tank

• Weight: 16 oz

Best for: Multi-side pneumatic connections.

Why it ranks #9: This 2.5-gallon steel tank has six 1/4-inch NPT ports and a 200 PSI rating, but its listed uses are auxiliary air tasks, not trailer brakes.

Six 1/4-inch NPT ports positioned on various sides give the VIAIR 2.5-gallon tank flexible connection locations for a compact compressed-air supply. Its steel construction and 200 PSI working-pressure rating make the operating limit and material explicit for buyers considering trailer pneumatic accessories.

The 2.5-gallon capacity provides a defined reservoir size for keeping compressed air available, while six 1/4-inch NPT ports on various sides give multiple connection points for a layout that needs more than one outlet. VIAIR identifies air shocks, tires, air tools, and simple garage or household tasks as uses, making this a broad utility tank rather than a specified trailer air-brake replacement. Its 200 PSI rating and steel construction are practical selection details.

Skip it if you need a 2,850-cubic-inch air-brake reservoir with dual main ports; the Velvac 035107 lists that configuration.

This suits a buyer seeking a compact supply for air shocks, tires, or tools, with six connection points and a stated 200 PSI limit. Its 2.5-gallon volume is a boundary for higher-capacity trailer needs.
