Reducing Coupling 4 in x 2 in NPT

This Anvil reducing coupling connects a 4-inch female NPT pipe to a 2-inch female NPT pipe. It is made from malleable iron rated for Class 150 service. The fitting suits Schedule 40 piping systems in plumbing or industrial installations. Condition is new.

Replaces mismatched pipe sizes

Use this coupling when joining two different nominal pipe diameters in a straight run. It eliminates the need for separate reducer bushings and nipples. The jump is worth it when a single compact fitting simplifies assembly and reduces potential leak paths. Maximum operating pressure is 300 psi at 150 degrees F.

Questions about this item

What pipe schedule and NPT sizes does this 4 in x 2 in reducing coupling accept?

The coupling is rated for Schedule 40 pipe and has 4 in female NPT on one end and 2 in female NPT on the other.

How do you seal the threads correctly, and what mistake causes leaks?

Apply PTFE tape or pipe dope to the male threads only, then tighten two full turns past hand-tight; skipping the sealant or over-tightening cracks the malleable iron.
