High-Pressure up to 700 Bar
HSP Cupla
The Nitto Kohki HSP Cupla is a high-pressure quick coupling in steel with NBR seal for operating pressures up to 700 bar. With 58 items, the programme covers plugs (HP types) and sockets (HS types) in nominal sizes 2, 3, 4, 6, 66, 8, 10, 12, and 16. Back-pressure variants (R types such as 2HP-R) are also available for applications with elevated counter-pressure. The HSP Cupla is part of Nitto Kohki's core high-pressure series.
The wide nominal-size range and steel/NBR material combination make the HSP Cupla a versatile connection solution for hydraulic and high-pressure pneumatic applications up to 700 bar.
