Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe

Designed for low-pressure flow applications, this pipe is also known as Schedule 40.

Pipe—Fully Threaded

Male

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.

304/304L Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

Welded—Pipe has a weld bead on the inside.

Pipe—Threaded on Both Ends

Male

304/304L Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316/316L Stainless Steel—Pipe is the most corrosion resistant. It stands up to wet environments, just like 304 stainless steel pipe, but unlike 304 stainless steel, it will not corrode from salt water, chlorine solutions, and chemicals.

Welded—Pipe has a weld bead on the inside.

Standard-Wall Stainless Steel Unthreaded Pipe Nipples and Pipe

Also known as Schedule 40, this pipe has a thicker wall than our thin-wall stainless steel unthreaded pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak.

Pipe—Unthreaded

304/304L Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

Welded—Pipe has a weld bead on the inside.

Thick-Wall Stainless Steel Unthreaded Pipe Nipples and Pipe

Also known as Schedule 80, this pipe provides an extra-strong connection. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak.

Pipe—Unthreaded

304/304L Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

Extra-Thick-Wall Stainless Steel Unthreaded Pipe Nipples and Pipe

With an extra-thick wall, this Schedule 160 pipe is the strongest stainless steel pipe we offer. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak.

Pipe—Unthreaded

304 Stainless Steel—Pipe holds up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.

316 Stainless Steel—Pipe is the most corrosion resistant. It stands up to wet environments, just like 304 stainless steel pipe, but unlike 304 stainless steel, it will not corrode from salt water, chlorine solutions, and chemicals.

Seamless—Pipe has a smooth interior for unrestricted flow and is stronger than welded pipe.

Low-Pressure Stainless Steel Compression Pipe Fittings

Create quick, liquid-tight connections in medium-pressure applications with these connectors. They join rigid pipe of the same or different materials. Connectors have a gasket that permits moderate movement and misalignment of pipe ends.

Compression connectors slide onto pipe and hand tighten with the end nuts. You may need to tighten over time. These connectors have a Buna-N rubber gasket that resists oil, as well as mild chemicals and water. Replace the gasket when it’s worn out, or swap it out for a gasket with different properties. Silicone rubber gaskets resist temperature changes better than Buna-N rubber gaskets, and also keep their flexibility. Viton® fluoroelastomer rubber gaskets resist extreme heat, as well as chemicals, fuel, and oil.

Straight Connectors with Gasket
