Anvil Reducing Coupling 1-1/2" x 3/4" NPT

This Anvil reducing coupling connects pipes of different diameters in high-pressure systems. The malleable iron body is rated for Class 300 service with Schedule 80 pipe. Female NPT threads on both ends allow direct installation without additional adapters. It suits industrial plumbing and hydraulic applications requiring a durable transition fitting.

Installers needing a 500 psi pressure rating

The fitting handles demanding steam, air, oil, or water lines within its rated limits. It is not intended for low-pressure residential drainage or plastic piping systems. Buyers who require welded connections or flanged ends should select a different component. The NPT thread standard may not match metric or BSPT pipe threads used in some regions.

Class 300 Schedule 80 pressure rating

This specification determines whether the coupling withstands the system's maximum operating pressure and temperature. The 500 psi rating at 150°F is the critical limit for safe service. Verify that your pipeline design pressure and temperature stay within this envelope before installation. Exceeding these values risks joint failure and safety hazards.

Questions about this item

What pressure does the Class 300 NPT reducing coupling handle at 150°F?

The malleable iron reducing coupling is rated for 500 psi maximum operating pressure at 150°F.

What pipe schedule and thread sizes does this reducer coupling fit?

It connects Schedule 80 pipe with 1-1/2" female NPT on one end and 3/4" female NPT on the other.

How do you install this NPT reducing coupling without damaging the threads?

Apply PTFE tape or pipe thread sealant to the male threads, hand-tighten, then wrench-tighten one to two turns — over-tightening cracks the malleable iron.
