Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
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.
Straight Reducers
- For Use With: Air, Steam, Oil, Water, Natural Gas
- Specifications Met: ASTM A234, ASME B16.9
- Pipe Nipples and Pipe: Use Schedule 40 steel
- Flanges: Use Class 150 steel

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings
With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications. Weld them flush against pipe for a smooth connection that permits maximum flow. These fittings have beveled ends that create a trough for a leak-resistant, permanent weld. Made of steel, they’re for use in noncorrosive environments.
