Quick couplings
High Flow Cupla
The Nitto Kohki High Flow Cupla is a quick coupling with an enlarged flow cross-section, designed for applications where conventional couplings would cause unacceptable flow restriction. The 18-item range covers nominal sizes 2, 3 and 4 as plug (P) and socket (S), in three material/seal combinations: brass with FKM, stainless steel (SUS) with FKM, and stainless steel (SUS) with EPDM. This selection covers a wide range of media, from general hydraulics to water and steam applications (EPDM).

How to choose High Flow Cupla
What matters when choosing: properties, comparison and typical applications.
Technical features
Body material and seal overview
| Body material | Seal | Nominal sizes | Plug | Socket |
|---|---|---|---|---|
| Brass | FKM | 2, 3, 4 | HFL-2P, HFL-3P, HFL-4P | HFL-2S, HFL-3S, HFL-4S |
| Stainless steel (SUS) | FKM | 2, 3, 4 | HFL-2P (SUS), HFL-3P (SUS), HFL-4P (SUS) | HFL-2S (SUS), HFL-3S (SUS), HFL-4S (SUS) |

Typical applications
Typical applications: Hydraulic circuits with high flow rates and low tolerable pressure drop, coolant return lines in machine tools, hot-water and steam lines (EPDM variant, SUS), chemical process plant with corrosive media (SUS/FKM), laboratory circulators and thermostat baths, and all applications where coupling geometry would otherwise limit system flow.
