NPT Male / Female Adaptor

NPT (National Pipe Thread) Adaptor are the most popular type of seal for pressure calibration systems in the U.S. and Canada. NPT male adapters have a taper thread that wedges into the female NPT adapter. They seal due to the "out of roundness principle" which means that the male stretches the female fitting until there is so much force that the connection can hold pressure. One of the challenges with this design is that if you connect stainless steel to stainless steel then over-tightening or poor lubrication can cause gauling and damage to the threads. Thread sealant is needed to seal but only 2 turns of thread sealant is required. Any more than that and the seal can leak around the thread sealant

√ Precision pipe fittings for instrumentation and process control
√ Fine threads constructed to ensure leak-free & reliable systems
√ Male threads are protected with plastic cap
√ Various materials including SS316, Brass and Carbon steel
√ Many choice of connections and configurations are available
√ Female NPT to same size male NPT

NPT connector fittings come in thread sizes from 1/8NPT to 2NPT depending on listed fitting choices. We offer a comprehensive range of hydraulic adapters which are available in numerous sizes, configurations, and grades.
