Standard-Wall Aluminum Unthreaded Pipe Nipples and Pipe

With a thicker wall than our thin-wall aluminum pipe, this pipe is also known as Schedule 40. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. This pipe meets ASTM B241, so it meets strict manufacturing requirements to ensure performance and quality. Made of aluminum, it’s lightweight with good corrosion resistance.

Pipe—Unthreaded

Pipe

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

Medium-Pressure Aluminum Butt-Weld Pipe Fittings

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight with good corrosion resistance.

Low-Pressure Aluminum Butt-Weld Pipe Fittings

Also known as Schedule 10 fittings, these are the thinnest aluminum pipe fittings we offer. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight and have good corrosion resistance.

Standard-Wall Aluminum Quick-Connect Pipe Nipples and Pipe

Build a compressed air system in half the time it would take to build a copper or steel system. Also known as Unipipe, this pipe is part of a quick-connect system. The compatible fittings connect to this pipe when you finger tighten their collar and then use a wrench for the final quarter turn. A compression ring and O-ring inside the fitting seal it onto this pipe. Use a deburring scraper (sold separately) to smooth rough edges left behind after trimming the pipe to size.

Pipe—Unthreaded

Male

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

Powder-Coated 6060 Aluminum—Anodized and powder-coated fittings have a decorative matte black finish.

Blue—Blue pipe is often used for compressed air systems.

Gray—Gray pipe is often used for vacuum systems.
