Standard-Wall Stainless Steel Threaded Pipe Nipples and Pipe

Intended for low-pressure flow, this pipe is also known as Schedule 40. It’s made of stainless steel for excellent corrosion resistance.

Pipe—Fully Threaded

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.

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.

Welded—Pipe has a weld bead on the inside.

Thread Sealant

Applicator-Top Can

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns. Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

High-Temperature PTFE Pipe Nipples and Pipe for Harsh Chemicals

This PTFE pipe can withstand a wider temperature range than any of our other plastic pipe for chemicals. It has the chemical resistance to stand up to acid and solvents. Also known as Schedule 80 pipe, it has thick walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so this pipe is commonly used in high-purity processes, such as semiconductor and clean room applications. It has a super-smooth interior for unrestricted flow. Pipe meets ASTM D1710 specifications and testing requirements for material quality.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Pipe—Fully Threaded

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