Medium Pressure up to 75 Bar
SP Cupla Type A
The Nitto Kohki SP Cupla Type A is a steel quick coupling for medium-pressure service up to 75 bar, covering the widest nominal size range in its group: plugs (P) and sockets (S) in nominal sizes 2, 3, 4, 6, 8, 10, 12 and 16. The 146-item range is available in two seal variants, NBR for general compressed-air and hydraulic duty and FKM (fluoroelastomer) for elevated media and temperature resistance. All types follow the Type-A coupling principle, allowing push-to-connect engagement with automatic valve locking on disconnection.

Typical applications
Typical applications: Hydraulic presses, injection moulding machines and machine tools in the medium-pressure range up to 75 bar, compressed-air systems with quick-change couplings, metalworking coolant lines, chemical plant with mineral oil or fuel contact (FKM variants), and applications that need a broad nominal size range within a unified coupling system.
