Patented NSH Series couplings feature a pressure-balanced non-spill design and a 100% metal-free, spring-free flow path at a very competitive price. These innovative couplings are easy to use (single-handed operation) and provide high flow capacity. Their non-spill design virtually eliminates spills, minimizes downtime and enhances operator safety. All plastic flow path allows for high flow, low turbulence, and no corrosion. The non-spill design allows you to disconnect under pressure with no spills. One-hand connection and disconnection thanks to the CPC thumb latch.
