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 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.

Gauges that meet OSHA 29 CFR 1910.177 are designed to safely fill sidewall truck tires. They have a hose long enough to inflate the tires from a safe distance.

Gauges with a rubber sleeve prevent metal-to-metal contact with your tire to avoid damaging it. Gauges with lock-on threads securely attach to your valve stem threads, so you don’t have to hold the valve stem.

Gauges with a clip-on Schrader connection don't require you to hold them while you’re filling up your tire.

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. Those for a 0.305”-32 thread size fit standard-bore Schrader valves. Those for a 0.485”-26 thread size fit large-bore Schrader valves. Do not use these air chucks with tire inflator gauges.

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.

Chucks with 2 outlets can be used at different angles and have an extended reach, so they’re ideal if your valve is hard to reach or in an awkward spot.

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

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.

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.
