|NEWTSP CuplaSocket with Ball Valve 1/4 – 1"
One-piece design of TSP Cupla socket and ball valve. Sleeve stopper mechanism prevents accidental disconnection (when the valve is open).
Socket valve can be opended and shut off while socket and plug are connected.
Ball valve design provides for high flow rate.
High viscosity fluid such as grease can be applied.
The handle of the ball valve locks the sleeve to prevent disconnection of the plug during use. [Specification]
