Nitto Kohki Pneumatic Solutions
Noble Gases and Vacuum
Nitto Kohki PCV Cupla quick couplings are designed for noble gas lines and vacuum applications where leak-tightness and media purity are critical. The 95-item range covers the PCV series in brass with two seal options: CR (chloroprene, for general vacuum and inert gas service) and FKM (fluoroelastomer, for elevated temperature and chemical resistance). The PCV470, PCV600, PCV630, PCV800, PCV950, PCV1270 and PCV1590 series cover a broad connection range, each with -0, -2 and -3 suffixes for different port geometries.
The brass body and precise valve geometry minimise dead volume during coupling and prevent contamination of the gas line with atmospheric air. Both seal variants (CR and FKM) are suitable for inert gases such as nitrogen, argon and helium as well as for vacuum lines.

Typical applications
Typical applications: Nitrogen, argon and helium supply lines in laboratory and production, vacuum lines in analytical instruments and semiconductor fabrication, inert shielding gas feed for welding, laser cutting gas supply, and applications where leak-tightness and minimum contamination of the gas line are essential.
