NS212

See NS212 Products

NS212 Series couplings were built on the company's proven platform of non-spill valves designed to provide fast, safe and virtually leak-free fluid line connections. NS212 is an easy, twist-to-connect coupling with an integrated locking mechanism and double-sided non-spill shutoff valves. The NS212 is also chemically resistant making it ideal for a diverse range of applications.
