Power Tank HiPPO2 Hi-Pressure Push-On Tire Chuck

The Power Tank HiPPO2 is a second-generation hi-pressure push-on tire chuck rated to 1,000 psi working pressure, designed for overlanders and off-road drivers who need fast, reliable tire inflation across a wide range of valve stem types, including short TPMS metal stems, Apex RPV stems, and other hard-to-access stems as short as 7mm. The chuck ships with a 45-degree elbow and fits any generation Power Tank tire inflator or any inflator with 1/4 inch NPT threads.

Fits the Stems Others Miss

The HiPPO2's slimmer profile and shorter depth compared to the first-generation chuck allow it to seat on valve stems that a bulkier chuck cannot reach. Short TPMS metal valve stems, Apex RPV stems, and recessed or hard-to-access stems as short as 7mm are all within its range. For a buyer airing up in the field, that means fewer situations where the chuck simply won't connect, and less time crouching at the wheel trying to make it work.

Grip That Holds in Cold Weather and Gloves

Version 2 adds larger ridges around the chuck body, giving a more secure grip when hands are cold, wet, or gloved. On a trail in early morning or in winter conditions, maintaining a firm hold on a small fitting under pressure matters. The redesigned grip surface reduces the chance of losing control of the chuck during connection or disconnection.

1,000 psi Working Pressure for High-Pressure Systems

The HiPPO2 carries a 1,000 psi working pressure rating, matching the output capability of CO2-based tire inflation systems like the Power Tank lineup. The 1/8 inch FPT female threads on the chuck body, combined with the included 45-degree elbow (1/4 inch FPT female threads), allow connection to any generation Power Tank tire inflator or to third-party inflators with 1/4 inch NPT threads. Most setups need no additional adapters.

Features

• Push-on design: seats on any Schrader valve, including stems as short as 7mm
• Slimmer, shorter profile: reaches short TPMS metal stems, Apex RPV stems, and hard-to-access valve stems
• 1,000 psi working pressure: rated for high-pressure CO2 and compressed-air tire inflation systems
• Included 45-degree elbow: 1/4 inch FPT female threads fit any generation Power Tank inflator or any inflator with 1/4 inch NPT threads
• Larger grip ridges: improved hold in cold weather or while wearing gloves
• 3/4 inch diameter body: 1/8 inch FPT female threads on the chuck

Specifications

Who This Is For and Isn't

The HiPPO2 suits overlanders, off-road drivers, and anyone running a CO2 or high-pressure compressed-air tire inflation system who needs to air up tires with short, recessed, or otherwise hard-to-reach Schrader valve stems. It pairs directly with Power Tank tire inflators and any inflator using 1/4 inch NPT threads.

The HiPPO2 is an open chuck and cannot be connected directly to an air source without an inline switch, trigger, or on/off valve in the line. It is not a no-air-loss chuck and is not suitable for inflating shocks or other low-volume, precision-fill applications.

Common Questions

Will the HiPPO2 work with my existing Power Tank inflator?

The HiPPO2 tire chuck ships with a 45-degree elbow threaded to 1/4 inch FPT female, which fits any generation Power Tank tire inflator. It also connects to any third-party tire inflator with 1/4 inch NPT threads, so it is compatible with most CO2 and compressed-air inflation systems without additional adapters.

What is the shortest valve stem the HiPPO2 can connect to?

The HiPPO2 push-on tire chuck works with valve stems as short as 7mm. Its slimmer profile and reduced depth compared to the first-generation chuck allow it to seat on short TPMS metal valve stems, Apex RPV stems, and other hard-to-access stems that a wider or deeper chuck body cannot reach.

Can I use the HiPPO2 to inflate shocks or air bags?

No. The HiPPO2 is not a no-air-loss chuck and is not designed for shocks, air bags, or other low-volume applications where precise, controlled fill is required. It is built for tire inflation on Schrader valves and should be used with an inline switch, trigger, or on/off valve rather than connected directly to an open air source.

Does the HiPPO2 work with TPMS valve stems?

Yes. The HiPPO2 tire chuck is specifically designed to fit short TPMS metal valve stems, which many standard chucks cannot seat on due to their depth or diameter. It works with any Schrader valve, including TPMS stems, Apex RPV stems, and other short or recessed stems down to 7mm in length.

What changed from the first-generation HiPPO to the HiPPO2?

The HiPPO2 features a slimmer profile and shorter depth than the original, allowing it to connect to a wider range of valve stems including short TPMS metal stems and Apex RPV stems. Power Tank also added larger ridges to the chuck body in version 2, improving grip when hands are cold or when wearing gloves during field inflation.
