Working temperature range-20˚C to +80˚C Standard material• Above specifications apply only to Cuplas. Max working pressure and working temperature range may varydepending on tube materials you use with and the working temperature.

Lightweight and compact push-toconnect operation.
Responding to requirements of modularcombinations.
• Compact socket with built-in valve and 14 mm OD sleeve.
Suits applications calling for compact and modular components.
• Just push in the plug to the socket for connection by easy one hand operation.
• Plated brass for corrosion resistance adopted for the body.
Stable performance for long life.
• A wide line-up of end configurations (female and male threads, hose barbs,manifolds) enables suitability with a wide range of piping applications suchas pneumatic, scientific and medical equipment.
• Also available with quick connect/disconnect Tube Fitter type.
Note: Fluid will flow out from the plug side when disconnected.
Take necessary precaution if the fluid is water.
