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.
304 stainless steel pipe has very good corrosion resistance. 316 stainless steel pipe has excellent corrosion resistance.
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 Plastic Pipe for Water
With thicker, stronger walls than standard-wall pipe, this Schedule 80 pipe can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. It’s made of PVC, which has good corrosion resistance. Pipe meets ASTM D1784 and ASTM D1785 specifications and testing requirements for material quality.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.
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.
