Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Standard-Wall Brass Unthreaded Pipe
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Specifications Met: ASTM B43
With two unthreaded ends, this pipe is designed for brazed connections, which are stronger than threaded connections and less likely to leak. It is also known as Schedule 40. Pipe is seamless, so it has a smooth interior for unrestricted flow. It is brass, which has good corrosion resistance.
