TOPRING 20.448 UNISAFE 1/4 (F) NPT FITTING

Fitting designed to release air pressure before disconnection to reduce the risk of injury from whiplash.
Valve socket operated independently of the locking socket. When the valve socket is moved
to stop the air flow, it releases the pressure downstream.
Easy disconnection and connection with zero pressure.
Automatic connection.
Six-ball locking mechanism, equally distributing the load, which helps counteract wear and ensures an excellent connection, while reducing hose twisting.
Knurled socket for better grip.
This model can be used as an isolation valve to shut off the compressed air supply.
