NPTLOK Male Run Tee
NPTLOK male run tee is a T-shaped 3-way tube fitting used in a fluid or a gas transfer system. There is a male thread on one end and two tube connections on the other two ends. Two tube connections permit the gas or the flow of fluid to go through the pipeline, at the same time diverting a part medium to another branch line. The tube connection of the male run tee is a double ferrule design, which provides reliable leak-free connections for instrumentation and analyzer application.
Male run tee is available in a large range of sizes and materials, which makes them adaptable to different systems. The tube connection sizes are from 1/8’od’-1 1/2”od, the thread is available in NPT, BSPP, Metric, and so on.
Material options: stainless steel 304 / 316, brass, carbon steel, Monel, Super Duplex.
