The Nitto Kohki TSP Cupla series is engineered for medium-pressure pneumatic and hydraulic circuits operating at up to 75 bar, delivering a rated flow coefficient (Cv) of up to 1.4 and a proof pressure of 1.5x the working pressure in accordance with ISO 6150 Class C requirements. The push-to-connect sleeve-type coupling mechanism allows single-hand connection and disconnection under residual pressure, with a minimum pull-out force of 60 N and a maximum leakage rate below 3 cm³/min at 7 bar - critical for contamination-sensitive assembly and test environments.

As an authorised stocking distributor for Nitto Kohki pneumatic quick-connect couplings, esd.equipment carries 288 TSP Cupla variants - spanning body sizes 20SF to 40SF, valve configurations (single-valve, double-valve, open-flow), and end connections from Rc 1/8 to Rc 1/2 (JIS B 0203) as well as NPT and BSPP threads - all compliant with RoHS and REACH directives and available from warehouse stock.
