1502-08-04 90° Elbow, 1/2" NPTF Female x 1/4" NPSM Swivel

These fittings are made from durable, pressure-resistant forged carbon steel with a zinc-trivalent anti-corrosion coating. They come in both NPT (National Pipe Thread) and NPSM (National Pipe Straight Mechanical) types. NPT threads are tapered and provide a reliable seal, commonly used throughout the U.S. The NPSM fittings include a 30° seat that aligns with the male fitting for a secure, leak-resistant metal-to-metal connection.
