    NSH Series couplings are general purpose versions of CPC's pressure-balanced, non-spill, ChemQuik® CQG couplings. Molded polypropylene, EPDM seals and a 100% springless and metal-free flow path provide broad chemical resistance and exceptionally high flow capacity, allowing instant disconnects (and reconnects), even under pressure. The non-spill design of the polypropylene NSH coupling virtually eliminates spills, minimizes downtime and enhances operator safety in a very low cost package.
