About Pipe and Fittings

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

Standard-Wall Brass and Bronze Threaded Pipe Nipples and Pipe

Also known as Schedule 40, this pipe is for use in low-pressure flow applications. It is brass, which offers good corrosion resistance.

Pipe—Threaded on Both Ends

Male

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

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.

Standard-Wall Brass and Bronze Threaded Pipe Nipples and Pipe Assortments for Drinking Water

Image of Product. Front orientation. Pipe and Fittings. Standard-Wall Brass and Bronze Threaded Pipe Nipples and Pipe Assortments for Drinking Water, Male.

Male

Keep various lengths of brass pipe on hand for applications requiring good corrosion resistance. The pipe in these assortments is threaded, so you can take apart its connections for maintenance and repair. They’re Schedule 40, so they should be used in low-pressure applications. This pipe is seamless, so it has a smooth interior for unrestricted flow, and it’s stronger than welded pipe. Fully threaded pipe nipples are also known as a close nipple; they are threaded on each end to the center.

NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.
