Choosing the right Nitto Kohki Cupla
Define application and medium
Choose the series based on the medium and cleanliness requirement. For semiconductor and ultra-clean media, the Semicon lines SCT and SP with PTFE, FEP or Kalrez are suitable. For general compressed air and fluid use, industrial series such as TSP, HSP and Lever Lock are designed.
Material and seal
Match housing and seal material to the medium and temperature:
- Stainless steel (SUS) for corrosive or high-purity media
- Brass, steel or aluminum for standard applications
- Seals in NBR, FKM or Kalrez depending on chemical resistance
Single or multi-line coupling
For several parallel lines, the Multi Cupla offers a compact solution with a single connection action. Drip-free Zerospill variants minimize media loss on disconnection and suit sensitive or costly fluids.
Which Cupla series fits?
| Criterion | Semicon (SCT/SP) | Multi Cupla | Industrial (TSP/HSP) |
|---|---|---|---|
| Use | Semiconductor, ultra-clean | Multi-line connection | Compressed air, fluids |
| Material | PTFE, FEP, SUS | Brass, aluminum | Steel, SUS |
| Seal | Kalrez, FEP | NBR, FKM | NBR, FKM |
| Feature | High purity | Parallel lines | Rugged, universal |
| Zerospill | partly | as CL variant | - |

Frequently asked questions about Nitto Kohki
What is a Nitto Kohki Cupla?
Cupla is Nitto Kohki's quick coupling brand. The couplings connect compressed air and fluid lines quickly and without tools, and are available in numerous series for industry, fluid handling and semiconductor manufacturing.
What are the Semicon SCT and SP series used for?
The Semicon lines SCT and SP are designed for high-purity applications in semiconductor manufacturing and fluid handling. They use ultra-clean compatible materials such as PTFE, FEP and Kalrez seals.
What does the Zerospill version mean?
Zerospill couplings are designed so that virtually no medium escapes when disconnected. This reduces loss and contamination and is especially suited to costly or sensitive fluids, for example the Multi Cupla in its CL variant.
Which materials and seals are available?
Depending on the series, housings are available in stainless steel (SUS), brass, steel or aluminum. Seals include NBR, FKM and Kalrez, matched to the medium, temperature and chemical resistance.
Does Nitto Kohki also offer tools besides couplings?
Yes. The range includes portable tools such as the HB-15B edge milling cutter and the CBR-03 circuit beveler for metalworking, complementing the extensive Cupla coupling program.
