POLY HD NIPPLE
The Poly Hd Nipple is a short length of pipe with threaded ends for connecting two threaded pipes. It has male National Pipe Taper (NPT) threads for connecting to female NPT threaded pipes, creating a tighter seal than straight threads. This fitting is precision molded in polypropylene, which resists most chemicals, has excellent dimensional stability, and is sterilizable. In addition, it is reinforced with fiberglass for added durability, strength, and chemical resistance.
