SUPER CUPLA suits air piping up to 1.0 MPa {10 kgf/cm2} where the coupling hangs directly on a power tool and weight matters: the 19.5 mm outside diameter sleeve, the steel or aluminum alloy body and one hand push-to-connect are its argument against COMPACT CUPLA and CUBE CUPLA, which are two-way shut-off at the same 1.0 MPa {10 kgf/cm2} and are chosen when the line has to close on both sides. Its end configurations cover hose barb, urethane hose, threads and Tube Fitters in 1/8 inch and 1/4 inch, and model 02S20P lets it work against HI CUPLA sockets. For air lines rated 1.5 MPa {15 kgf/cm2}, HI CUPLA, HI CUPLA 200, FULL BLOW CUPLA or LINE CUPLA 200 are the correct range, and fluids other than air fall outside the air-only rating of SUPER CUPLA.

Interchangeability and size groups

Sockets and plugs can be connected regardless of end configurations and sizes. Interchangeable with MOLD CUPLA (Models K-01P, K-02SP, K-03SP and K-90SN are named on the page). Sockets of HI CUPLA models 10, 17, 20, 30, 40, and 60 can be connected when 02S20P is used.

Safety and application notes

Before use, please be sure to read "Safety Guide" described at the end of this book and "Instruction Sheet" that comes with the products.
To mount on urethane hose, slide it over to the hose barb and tighten the nut until it is flush against the hose barb base.
It is recommended that grease GRE-M1 is applied to the inside of the nut (threaded part and hose contact part) for easy tightening.
