About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.

316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

Retaining Caps


1050 Spring Steel	Plastic

400 Series Stainless Steel

Use these caps to hold components in place and protect shaft ends. Install these caps with a hammer or push them into place by hand.

Corrosion-Resistant Coated—Corrosion-resistant-coated finish is more corrosion resistant in wet environments than zinc-plated finish. Also known as black luster.

Nickel Plated—Nickel-plated finish has excellent corrosion resistance and a decorative appearance.

Zinc Plated—Zinc-plated finish is corrosion resistant in wet environments.
