Fittings crafted from durable, pressure-resistant forged carbon steel, enhanced with a zinc-trivalent anti-corrosion coating. NPT, or National Pipe Thread, is a tapered thread widely adopted in the U.S. for its reliable seal, while NPSM is its straight counterpart. The Female National Pipe Straight Mechanical (NPSM) fittings feature a 30° seat, which aligns with the male fitting to ensure a tight, leak-resistant metal connection.
