NITTO KOHKI 25SH Air Quick Coupler for Oxygen Gas Applications
The NITTO KOHKI 25SH (Hi Cupla) is a premium industrial-grade female quick coupler (Socket) made in Japan. The "SH" model is designed with a hose barb end for direct connection to air or gas hoses. The body is made of special hardened steel, giving it outstanding resistance to wear, impact, and high pressure, providing maximum safety in general air and gas supply systems. This model features a tightly engineered internal structure and leak-prevention seal system to meet high industrial safety demands, particularly for oxygen gas applications in metal cutting or gas welding, effectively preventing gas leak hazards.
Features
Smart Quick-Connect System (One-Way Shut-off): The socket side features a built-in automatic shut-off valve that instantly stops air or gas flow when the plug is disconnected for maximum safety.
Hardened Steel Body: Treated with NITTO KOHKI's proprietary heat treatment, providing exceptional resistance to abrasion and withstanding tens of thousands of connections and disconnections without wear.
Safety-Oriented Design: The 5/16-inch tapered, deeply barbed end allows for a tight, secure hose clamp fit over rubber or air hoses, preventing slipping even under accumulated pressure.
Made in Japan: Confident in world-class manufacturing standards, high precision, and strict quality control systems.
Applications
