These fittings, made from durable, pressure-resistant forged carbon steel, are enhanced with a zinc-trivalent anti-corrosion coating. NPT, or National Pipe Thread, is a tapered thread commonly used in the U.S. for its dependable seal, while NPSM is its straight-threaded counterpart. The Female National Pipe Straight Mechanical (NPSM) fittings feature a 30° seat that aligns with the male fitting, ensuring a secure, leak-resistant metal connection.
