Power Tank TPG RED 150 psi Analog Modular Tire Pressure Gauge

The Power Tank TPG RED is a 0–150 psi silicone-filled liquid analog tire pressure gauge built around the RED MOD quick-switch coupler system, making it a compact standalone option for checking and monitoring tire pressures on trucks, trailers, and off-road vehicles. It ships with a precision gauge, a quick-switch coupler, and a HiPPO2 Hi-Pressure Push-On/Pull-Off tire chuck, and accepts RED MOD accessory attachments sold separately.

Built for Cold Weather and High-Pressure Tires

The TPG RED uses a silicone-filled gauge rather than the glycerin fill common in lower-cost gauges. Glycerin thickens in cold temperatures and slows needle response; silicone stays fluid across a wider temperature range, so the gauge reads accurately whether the air is cold at a pre-dawn trailhead or warm at a summer track day. The 0–150 psi range and 2% accuracy rating (+/- 3.0 psi) make the TPG RED a practical choice for high-pressure truck and trailer tires running 60 psi and above, where a sluggish or inaccurate gauge creates real risk.

Modular RED MOD System

The TPG RED uses the same RED MOD attachment system found across the Power Tank Ventoso inflator gauge lineup, in a more compact package. The included quick-switch coupler lets a user swap tire chucks without tools, moving between standard Schrader valve stems and other chuck styles as the job changes. A 2-foot hose extension and a push-on tire chuck are available as separate RED MOD accessories, useful for reading pressures between laps or reaching recessed valve stems without repositioning.

Standalone Pressure Monitoring with Monster Valves

The TPG RED connects directly to a Schrader valve, so it works as a standalone pressure check tool independent of any CO2 system. When used alongside Power Tank Monster Valve high-flow valve stems, the gauge can monitor tire pressure second-to-second during airing up or airing down, giving a continuous read rather than a spot check. This makes it useful at the trailhead before a descent and at the pump afterward.

Features

• Pressure range: 0–150 psi analog liquid gauge
• Silicone fill: maintains accurate needle response in cold temperatures where glycerin-filled gauges slow down
• Accuracy: 2% accuracy, +/- 3.0 psi
• RED MOD system: quick-switch coupler accepts interchangeable RED MOD tire chucks and hose extensions (sold separately)
• Included: precision gauge, quick-switch coupler, HiPPO2 Hi-Pressure Push-On/Pull-Off tire chuck
• Schrader valve compatible: works as a standalone gauge or alongside Monster Valve high-flow valve stems

Specifications

Who This Is For and Isn't

The TPG RED suits overlanders, off-road drivers, and track users who need a reliable, cold-weather-capable pressure gauge for high-pressure truck and trailer tires (60 psi and above) and want the flexibility of the RED MOD modular chuck system. It pairs directly with Power Tank Monster Valve high-flow valve stems for continuous pressure monitoring during airing up or airing down.

The TPG RED is a pressure gauge only and does not supply or release air on its own. It does not include a hose extension; the 2-foot RED MOD hose extension is a separate accessory. The gauge is not covered under Power Tank's 5-year component warranty, which explicitly exempts gauges.

Common Questions

What pressure range does the TPG RED cover?

The Power Tank TPG RED reads from 0 to 150 psi on a liquid analog gauge, making it suitable for high-pressure truck and trailer tires as well as lower-pressure off-road tires. Its 2% accuracy rating and +/- 3.0 psi tolerance apply across the full range.

What comes included with the TPG RED?

The Power Tank TPG RED ships with a precision analog gauge, a RED MOD quick-switch coupler, and a HiPPO2 Hi-Pressure Push-On/Pull-Off tire chuck. A 2-foot hose extension and additional chuck styles are available separately as RED MOD accessories.

Why does silicone fill matter compared to glycerin?

The TPG RED uses a silicone-filled gauge rather than the glycerin fill found in many standard gauges. Glycerin thickens in cold temperatures, which slows needle movement and can affect reading accuracy. Silicone maintains its fluid properties in cold conditions, so the gauge responds consistently at low ambient temperatures.

Can the TPG RED be used while airing up or airing down?

Yes. The TPG RED connects to a Schrader valve and, when used with Power Tank Monster Valve high-flow valve stems, can monitor tire pressure continuously during airing up or airing down rather than requiring the inflation source to be disconnected for each spot check.

What RED MOD accessories are compatible with the TPG RED?

The TPG RED uses the same RED MOD attachment system as the Power Tank Ventoso inflator gauge lineup. Compatible accessories sold separately include a 2-foot hose extension for stand-away readings and additional push-on tire chucks for faster pressure checks between uses.

Is the TPG RED covered under the Power Tank warranty?

Power Tank offers a 5-year component warranty on its tire inflator products, but that warranty explicitly exempts gauges. The TPG RED gauge itself does not fall under the 5-year coverage; Power Tank does offer repair services and replacement components after the warranty period at a stated discount.
