TECHTUBE© NPT nipples are manufactured based on ASTM A733 standard and ASME B1.20.1 standard for thread dimensions. They are produced from a section of welded or seamless pipe (ASTM A312), which is threaded at both ends (TBE) or just one end (TOE).
Our NPT nipples (National Pipe thread taper) are machined with a conical shape. The nipples serve to join two connections with female termination with the same diameter. They allow to maintain the same direction of the fluid. Commonly this type of connector is used for venting or draining lines. It is connected to valves, elbows, bushing reductions and couplings, or any threaded connection.
