Standard-Wall Steel Pipe Nipples and Pipe
with Right-Hand and Left-Hand Threads
- For Use With: Air, Steam, Oil, Water, Natural Gas
- Specifications Met: ASTM A733, ASME B1.20.1, ASTM A53
- Fittings: Use Class 125 or 150 iron and steel
Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time. Also known as Schedule 40, this pipe is designed for low-pressure applications. It is welded, so there is a weld bead on the inside. Use in noncorrosive environments.
