Coilhose Pneumatics TGC129 Inflator Gauge 120 Psi

Product Description

The COILHOSE PNEUMATICS TGC129 is a zinc-body inflator gauge designed for tire and equipment inflation tasks in shop and field environments. It features an open-check design with a lock-on chuck, allowing the technician to attach the chuck to a valve stem and read pressure without continuously holding the trigger. The pressure range runs from 10 to 120 psi, covering standard passenger tires, light truck tires, and common pneumatic equipment. The 1/4-inch FPT inlet threads to standard air-line fittings, and the chrome finish provides corrosion resistance in typical shop conditions.

This inflator gauge suits automotive service bays, fleet maintenance shops, and general industrial environments where accurate tire or equipment inflation is required. The lock-on chuck frees both hands during inflation, which is useful when working in tight wheel wells or on equipment with difficult valve stem access. The open-check design allows air to flow freely when the chuck is attached, giving a live pressure reading throughout the inflation process. Licensed automotive technicians, fleet mechanics, and equipment service professionals are the primary users.

Key Features

• Lock-on chuck holds to valve stem without continuous hand pressure
• Open-check design delivers live pressure reading during inflation
• 10 to 120 psi operating range covers passenger, light truck, and equipment tires
• 1/4-inch FPT inlet fits standard shop air-line connections
• Zinc body with chrome finish for durability in shop environments

Compatibility

Designed as an OEM-style replacement or direct-install inflator gauge for shop air systems equipped with standard 1/4-inch FPT air-line fittings.

Installation Notes

Installation is performed by automotive or equipment service technicians. Depressurize the air line before threading the gauge inlet to the air supply fitting to prevent sudden pressure release. Use thread sealant appropriate for pneumatic fittings and tighten to hand-tight plus a quarter turn — do not overtighten zinc-body fittings. Verify gauge reads within the 10 to 120 psi working range before returning to service.
