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. The NS212 is an easy, twist-to-connect coupling with an integrated locking mechanism and double-sided non-spill shutoff valves. It is also chemically resistant and ideal for a diverse range of applications including printing and ink management, analytical instrumentation, electronic cooling and chemical handling. NS212 couplings provide high-flow fluid transfer in a small footprint. Materials of construction are glass-filled polypropylene body, 316 stainless steel spring, and EPDM seal material. Temperature range for this line is 32°F to 120°F (0°C to 49°C). Spillage when disconnecting is <0.025 cc and air inclusion when connecting is 0.009 cc. NS212 couplings will withstand vacuum to 45 psi, 3.1 bar. Note: The NS212 line does not mate with the original NS2 parts.
