NS4

See NS4 Products

NS4 Series couplings feature non-spill valves in a compact size, at a great price. Use the NS4 when even a few drops pose problems regarding safety, media cost or environmental regulations. These innovative couplings are lightweight, chemically resistant and easy to use. The nonspill design effectively eliminates spills, minimizes downtime and enhances operator safety. 

NS4 Series couplings are available with RFID-enabled IdentiQuik® technology. RFID-based IdentiQuik couplings redefine what's possible for controlling, protecting and streamlining fluid handling processes. IdentiQuik technology allows the robust transfer of fluid and information to identify device type or connected media, verify line connection accuracy or capture fluid and product data.
