AutoViteX Heavy Duty Tire Pressure Gauge Inflator for Trucks & RVs — 10–120 PSI, Dual-Head Lock-On Chuck, 1/4" NPT Kit

AutoViteX Heavy Duty Tire Pressure Gauge Inflator is a rugged 3-in-1 shop-grade tool delivering accurate 10–120 PSI readings, inflation and fine deflation with a dual-head air chuck and complete accessory kit.

Built for roadside and shop use, this all-in-one inflator combines a clear analog gauge with a lock-on air chuck, a straight plus 30° reverse-angle dual head for hard-to-reach rims, and a 1/4" NPT quick-connect inlet. The kit ships with valve cores, stem caps, thread seal tape and a 4-way tool so you can service and maintain tires without hunting for extras. Designed to tolerate heavy use on trucks, RVs and commercial vehicles, the assembly uses metal fittings, a rubber hose and a brass bleed valve to give reliable control when adjusting pressure.

How precise and reliable are the pressure readings?

The gauge covers a wide 10–120 PSI range and is calibrated for workshop use: it holds ±2 PSI accuracy between 80–120 PSI and about ±3 PSI under 80 PSI. A robust mechanical movement and a clear dial make readings fast and repeatable; avoid exceeding the 120 PSI maximum for safe operation.

• Range: 10–120 PSI for light to heavy vehicle tires
• Accuracy: ±2 PSI at 80–120 PSI; ±3 PSI below 80 PSI
• Durable internals to maintain calibration under heavy use
• Visible dial for quick, daylight-friendly readings

What features make inflation and deflation easier on trucks and RVs?

The dual-head chuck pairs a straight and a 30° reverse-angle connection so you can reach inner rims, dual-tire banks and tight wheel wells without awkward positioning. The lock-on chuck and steel trigger permit hands-free inflation while the brass bleed valve lets you bleed off small amounts of air for precision tuning.

• Straight + 30° reverse-angle dual head for access to inner and outer rims
• Lock-on chuck option for steady inflation during filling
• Steel trigger for robust throttle control in rugged conditions
• Brass bleed valve for fine pressure adjustments

Which accessories are included and how do they help maintain tires?

This kit arrives ready to use: a 1/4" NPT male quick-connect fitting, extra valve cores, both metal and ABS valve stem caps, thread seal tape and a four-way valve core tool are all in the box. Those extras let you replace leaking cores, seal the air inlet properly and protect stems for long-term serviceability.

• 1/4" NPT fitting for standard compressor hookups
• Four valve cores and four metal + four ABS stem caps for replacements
• 4-way valve core tool for installing/removing cores on-site
• Thread seal tape included for leak-free inlet connections

How should I use the gauge for the most accurate results?

After inflating, briefly press the bleed valve to remove residual hose pressure so the gauge needle can settle on the true tire pressure. Wrap the 1/4" NPT fitting with the supplied thread tape (4–6 turns) before connecting to avoid leaks, and disconnect the inflator when idle to prevent compressor cycling.

• Wrap 4–6 turns of thread tape on 1/4" NPT fitting before connecting
• Press the bleed valve briefly after inflation to get a true reading
• Do not exceed the 120 PSI maximum rating
• Disconnect from air supply when not in use to prevent unnecessary cycling

Who is this for? The AutoViteX Heavy Duty Tire Pressure Gauge Inflator is tailored to professional mechanics, fleet technicians, RV owners and serious DIYers who need a single, resilient tool to measure, inflate and fine-tune tire pressure on heavy vehicles. If you work with trucks, RVs, trailers or operate a busy garage, this kit supplies the fittings and spare parts to keep tires serviceable without stopping work to gather extras.
