SeriesLock™ NPT 100 Quick Disconnect Couplings and Inserts

A unique aseptic Spring-Free Flow Path® quick-connect fitting allows a larger volume of fluid to pass through it at lower line pressures. This optimized flow reduces restriction, turbidity, foaming, and bubbles. Recessed mating features protect contact surfaces and prolong the life of the O-rings helping to ensure a better seal. The audible click upon connection and the safety slide release are both features to help minimize accidental disconnects. Three body sizes in Small, Medium, and Large are available to accommodate a variety of connection sizes for NPT thread adapters. Additional sizes, materials, flow paths, and end connections available; contact us for a quote.
