Direct piping between Rc3/4 air lines and small couplings – Hi CUPLA 60SM / NK CUPLA Hose – Coupling and urethane hose combined
"HI CUPLA 60SM" is an excellent general-purpose coupling for connecting factory air supplies to pneumatic tool hoses. Key components are hardened to enhance strength. It is particularly resistant to wear and offers superior durability. The "NK CUPLA Hose with Full-Blow CUPLA" comes standard with a spring nut to prevent hose kinking and a polyurethane hose that excels in flexibility, durability, and wear resistance. The socket includes a "lock mechanism" to lock the sleeve and prevent accidental disconnection. Features: "HI CUPLA 60SM" ■ Enables direct piping between existing air main pipes (Rc3/4) and small diameter fittings ■ Mounting part size and shape: R3/4 (male thread) "NK CUPLA Hose" ■ Achieves low pressure loss and high flow rate. ■ Push-to-connect operation ■ When disconnected, exhausts residual pressure on the plug side, eliminating unpleasant noise and recoil.
