Non-spill couplings
NS6
NS6 is the non-spill coupling for the mid sizes 3/8" and 1/2". Both halves shut off on disconnect, so nothing escapes even with media where every drop counts, and downtime stays short. A soft-touch overmold gives a comfortable grip. Polypropylene body, EPDM, FKM or FFKM seal, rated from vacuum to 8.3 bar and 0 to 71 °C.
