Special couplings
Quick Couplings
This overview brings together the entire Nitto Kohki quick-coupling range with over 25 special and dedicated series beyond the standard pressure classes. From the flat-face FF and F35 Cupla through vibration-isolating, rotary and purgeable versions to plastic, paint and miniature couplings, there is a matching connector here for almost every special requirement.
Whether a non-spill flat-face coupling for clean disconnection, a Rotary Cupla against hose twisting, purge variants with integrated flushing, or corrosion-free Plastic Cupla - all series use the proven Nitto Kohki sleeve mechanism with automatic shut-off and are interchangeable with each other and with standard couplings to ISO 6150.

Product groups & typical applications
| Group | Examples | Property | Application |
|---|---|---|---|
| Flat-face Cupla | FF, F35 | non-spill, clean | sensitive media, hygiene |
| Rotary Cupla | Rotary Line, Rotary Plug | swivel | moving hoses, tools |
| Purge Cupla | Purge HI, Purge Line | integrated flushing | media change, cleaning |
| Plastic Cupla | BC Type | light, corrosion-free | chemicals, water, lab |
| Mini Cupla | Mini, Mini Super | miniature body | small devices, instrumentation |
| Paint Cupla | Paint | solvent-resistant | paint & coating lines |
Typical applications: special applications in mechanical engineering and manufacturing, paint and coating lines, hygiene and cleaning processes, moving hose connections and robots, laboratory and measurement technology, and anywhere standard couplings reach their limits on requirements such as swivelling, purging or corrosion resistance.
