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.

Standard-Wall Butt-Weld Stainless
Steel Unthreaded Pipe Fittings
Also known as Schedule 40 fittings, these have thicker walls than our thin-wall stainless steel unthreaded butt-weld fittings. 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.
Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

- For Use With: Air, Natural Gas, Oil, Water
- Specifications Met: ASTM A403/A403M, MSS SP-43, ANSI/ASME B16.9
- Pipe Nipples and Pipe: Use Schedule 40 stainless steel
- Flanges: Use Class 150 stainless steel

Standard-Wall Butt-Weld Steel Unthreaded Pipe Fittings
Butt-weld fittings allow for a smooth connection that provides maximum flow. They have beveled ends that, when flush to pipe, create a trough for a strong, permanent weld. Fittings are also known as Schedule 40. They are for use in noncorrosive environments.
Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

- Specifications Met: ASTM A234, ANSI/ASME B16.9
- Pipe Nipples and Pipe: Use Schedule 40 steel
- Flanges: Use Class 150 steel
