Anvil Malleable Iron Reducer Coupling Class 150

This Anvil reducing coupling connects pipes of different diameters using malleable iron construction rated for Class 150 service. It features a 2 inch female NPT end and a 1 inch female NPT end designed for Schedule 40 pipe. The black finish suits standard plumbing installations requiring a durable transition fitting.

Practical limits of the NPT threaded interface

The tapered NPT threads seal through thread engagement and require appropriate sealant or tape to prevent leaks at the 300 psi maximum operating pressure rating at 150 degrees Fahrenheit. Over-tightening can crack the malleable iron casting so installers must follow proper assembly torque guidelines. The Class 150 rating defines the pressure-temperature envelope so the fitting cannot be used beyond these stated limits.

Questions about this item

Should I pick the 2 in or 1 in NPT end for my pipe schedule?

The coupling joins a 2 in Female NPT pipe to a 1 in Female NPT pipe, both Schedule 40, so choose the end that matches the pipe you are connecting.

What does the Class 150 rating tell me about pressure handling in my system?

Class 150 means the fitting is rated for 300 psi maximum operating pressure at 150 °F, suitable for standard water, oil or gas lines within those limits.

How does the NPT thread standard affect sealing on this reducer?

NPT tapered threads create a metal-to-metal seal when tightened; use PTFE tape or pipe dope on the male threads to ensure a leak-free joint.
