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.

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.

Connect male- and female-threaded parts of different thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through. Attach your parts to these adapters and use a hex key to secure the connection. Made of 304 stainless steel, all will hold up in wet environments. O-rings on each side create a tight seal, making them good for vacuum and compressed-air applications.

For touch-free flushing on your toilets or urinals, attach these converters to your manual flush valves. They're activated by a motion sensor but also have a manual override option.
Style A should have the same consumption rate (water per flush) as your toilet or urinal. They help you comply with ADA when properly installed.
Style B replaces the handle of your urinal or tankless toilet. Use the tilt-down adapter (sold separately) when connecting Style B to flush valves that have 27" installation distance. It angles the sensor down to detect users and prevent unintended flushes.
Style C slips over the handle of your urinal or tankless toilet.
