Nitto Kohki Pneumatic Solutions
Mold Making
Nitto Kohki provides two quick coupling series for mould-making and temperature-control circuit connections on injection moulding tools: the HW Cupla (hot-water couplings, brass, FKM) for cooling and temperature-control circuits with hot water, and the Mold Cupla (brass) covering cooling water, air and other media connections at injection mould parting lines. The 58-item range includes adapters for braided hoses (BH series) and high-temperature variants (K-01PM-HH, K-02PM-HH).
The Mold Cupla K series is available as plugs (PH, PM, PF, PML) and sockets (SH) in nominal sizes 01, 02 and 03. The brass body offers adequate corrosion resistance for cooling water service. The BH adapters (BH-90, BH-120, BH-150, BH-190) connect Mold Cupla ports to braided hydraulic hoses in hose sizes 3M, 4M and 6M.

Typical applications
Typical applications: Temperature-control line connections on plastic injection mould tools, hot-water temperature-control circuits at elevated temperatures (HW Cupla, FKM), cooling water and compressed-air connections at mould parting planes (Mold Cupla K series), tool changers in injection moulding, and hose transitions to braided lines via BH adapters.
