About Air Compressors

Tire Inflator Gauges

Mate these gauges to a compressed air line to measure pressure while inflating tires. They are strong enough to stand up to constant use.

Indicator bar readouts slide out of the top of the gauge to display pressure readings.

Gauges with a 6-ft. or 15-ft. hose let you inflate truck tires from a safe distance. They meet OSHA 29 CFR 1910.177 for sidewall truck tires.

Securely attach gauges with lock-on threads to your valve stem threads, so you don’t have to hold the valve stem.

Gauges with a 0.485”-26 air outlet thread size have a large bore chuck head. Use these gauges with construction and heavy equipment that have large bore valves.

Air Chucks

Attach these chucks to your air hose so you can connect the hose to Schrader valves. Most often recognized from car and bike tires, Schrader valves are also commonly found on compressed air tanks and high-pressure hydraulic systems.

Chucks with a clip-on Schrader connection attach to the valve stem, so you don’t need to hold them as the valve fills.

Chucks with a sleeve-lock Schrader connection grab onto the valve by sliding the sleeve forward onto the valve. To disconnect, slide the sleeve back and pull out the valve.

Chucks with a threaded Schrader connection screw onto valves for a secure connection that you don’t need to hold in place.

Couplers for High-Pressure Fill Valves

Fill tanks and recharge struts—these couplers join hose to high-pressure fill valves with Schrader threads.

Some couplers meet SAE AS4395, an automotive industry standard for flared fitting dimensions.

70° elbow couplers are angled to access hard-to-reach valves.

Couplers with a shut-off valve let you control the flow of air by hand. When used with Schrader valves that have a core, the core depressor pin in these couplers press valves open to let air flow in.

Air Compressors with DC Motor

Compressor

Compressor with Tank

Get compressed air from a DC power source—these compressors can run on a 12-volt vehicle battery (not included) for use on trucks and heavy equipment, or a DC generator. Use them to inflate tires, clean filters, and operate light-duty tools, such as nailers, hammers, and small impact wrenches. For best results with a vehicle battery, use a deep-cycle, large-cell battery rated for continuous use.

Compressors with tank are mounted on a 10-gallon storage tank to handle more demanding applications, such as grinders, saws, and spray guns.

Optional mounting brackets allow you to mount a compressor to a vehicle chassis. Connector assemblies come with a three-foot hose and a connector that can be fixed to a panel or frame for operating compressors installed in difficult-to-reach locations, such as under a vehicle.
