Why this coupler

  • Automatic push-to-connect, twist-lock release — which means you push the plug in to connect single-handed, then twist the sleeve to release (these are commonly known as twist-lock couplers).
  • Schrader Standard & Heavy Duty interchange — which means it mates with the most common Schrader-style air couplers and plugs.
  • Lightweight aluminum body — which means less hand fatigue on air tools and hoses while keeping steel and brass where strength and sealing matter.
  • Reusable hose fitting — which means you can re-clamp it onto a fresh hose instead of scrapping a crimped fitting.

Push it on and it clicks home — clean airflow, no leaks, no fuss. Built to take daily shop abuse and keep sealing connection after connection.

What pressure is it rated for?
Rated to 300 PSI working pressure.

How do these connect and disconnect?
Push the plug in and it connects automatically (one-handed). To release, twist the sleeve — which is why these are often called twist-lock couplers.
