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.
- Less Valve — which means an unrestricted, free-flow path with no internal shut-off valve for maximum air flow.
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.
