In a "One Way Shut-Off", only the socket has valving to shut off the flow when disconnected; it is, therefore, installed on the pressure side of the line. The plug has no valving and exhausts the downstream line at disconnect.
FEATURES:
- High flow capacity for small coupler
- Only 5/8" diameter
- Socket weighs 1 oz.
- Precision leak-proof seal
- Positive locking mechanism
