Why this coupler
- Automatic push-to-connect — which means single-handed connection; push the plug in, retract the sleeve to disconnect.
- Tru-Flate (automotive) interchange — which means it mates with the most common automotive-style air couplers and plugs.
- High-flow tubular steel valve — which means strong air delivery with minimal pressure drop for better tool performance.
- Reusable hose clamp fitting — which means you can re-clamp onto fresh hose instead of scrapping a crimped fitting.
