High-Pressure Stainless Steel Socket-Connect Pipe Fittings

Forged for excellent strength, these heavy duty socket-connect fittings stand up to high-pressure applications. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.

Straight Connectors

Female

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

316/316L 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.

High-Pressure Stainless Steel Unthreaded Pipe Flanges

Use these heavy duty forged flanges for high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of same size together with a gasket (sold separately) to create an access point in a pipe line.

Forged Flanges

Socket-Connect

Forged flanges have better strength than cast flanges.

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

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

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.

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.

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