Low pressure up to 19 bar
HI Cupla ACE
The Nitto Kohki HI Cupla ACE is a plastic quick coupling for low-pressure service up to 19 bar, manufactured from PBT/POM with NBR seals. The range covers 25 items across the PH, PM, PN and PF plug series and the SH, SM and SN socket series, in nominal sizes 20, 30, 50, 60, 65, 80 and 85. G-suffix variants (50PNG-PLA, 65PNG-PLA, 85PNG-PLA) are earthed versions, and the HA series provides an alternative body geometry with the same materials and pressure rating.
PBT (polybutylene terephthalate) and POM (polyoxymethylene) give the ACE series greater rigidity and better chemical resistance than conventional polypropylene couplings, making them suitable wherever lightweight construction and corrosion-free operation are required.
