Nitto Kohki low-pressure pneumatic couplings (Cupla series) are engineered for working pressures up to 19 bar, combining one-touch push-to-connect operation with residual-pressure release mechanisms that drop line pressure to 0 bar on disconnection. Across the full range - from Micro Cupla body sizes 2.5 mm to Full Blow Cupla nominal bore 15 mm - leak rates remain below 1 cm³/min at maximum rated pressure, meeting ISO 6150 class B requirements for pneumatic quick-release couplings.
As an authorised distributor for Nitto Kohki pneumatic components, esd.equipment stocks 649 SKUs across 11 Cupla sub-series, covering body materials in brass, stainless steel (SUS316), and engineering polymer, with thread standards including R (BSPT), NPT, and G (ISO 228) from 1/8" to 3/4". Every coupling is supplied with full manufacturer documentation and conforms to ROHS and REACH requirements for industrial deployment.
