NS1 Series Couplings

NS1 Series couplings' compact closed-system design is packed full of features including non-spill shutoff valves that ensure drip-free disconnects and eliminate the need to purge air from the system.

Chemical resistant materials provide reliable strength and performance in a range of applications.
