How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Thin-Wall Butt-Weld Stainless Steel Unthreaded Pipe Fittings
Also known as Schedule 10 fittings, these are thin and lightweight. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

- For Use With: Air, Natural Gas, Oil, Water
- Specifications Met: ASME B16.9, ASTM A403, MSS SP-43
- Pipe: Use Schedule 10 stainless steel

Thin-Wall Socket-Connect Aluminum Unthreaded Pipe Fittings
Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings are aluminum, which is lightweight with good corrosion resistance.
