Featuring an innovative seal system, the zero-spill ZEL coupler model from Nitto Kohki reduces the spillages resulting from disconnection of quick-connect couplings by up to 96% compared to conventional models. Due to its flat face design, the undesired air ingress is also reduced by 94% against conventional couplers, allowing critical fluids to remain pure and intact. All of this can be managed by a simple one-hand operation. The two-way shut-off type coupler is available in different sizes up to 1” female thread. The materials are brass or stainless steel SUS 304. Packing material options, made of NBR, FKM or EPDM, allow the supply of fluid up to 180°C. the coupler is suitable for working with hydraulic oils, water, gases and air at up to 35 bar.
