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 Butt-Weld Aluminum Unthreaded 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.

Aluminum Unthreaded Pipe Flanges

Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges are aluminum, which is lightweight with good corrosion resistance.

Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld.
