304 Stainless Reducing Coupling

This 1-1/2" x 1/2" FNPT reducing coupling joins pipes of different diameters in fluid handling systems. It is made from 304 stainless steel for corrosion resistance and conforms to ASTM-A-351 material standards. The fitting meets MSS-SP-114 Class 150 pressure ratings for reliable service.

Thread Standard And Pressure Limits

Verify that your existing piping uses FNPT threads conforming to ANSME B 1.20.1 before installation. The fitting is rated for a maximum pressure of 300 psi and a maximum steam pressure of 150 psi. Ensure your system operating conditions stay within these limits.

Schedule 150 Piping Systems

This Class 150 coupling integrates into Schedule 150 stainless steel piping networks without requiring adapters. The FNPT female threads accept standard male pipe threads for a secure seal. It frees up design space by reducing line size directly at the joint.

Questions about this item

Does the reducing coupling come with thread sealant or gaskets, or must they be purchased separately?

The coupling is supplied as a single fitting; thread sealant, tape or gaskets are not included and must be sourced separately for the FNPT connections.

The fitting is listed as Class 150 with a 300 psi pressure rating — which figure should I use for water at ambient temperature?

For water at ambient temperature the 300 psi maximum pressure rating applies; the 150 psi figure is the maximum steam pressure limit.

What does the 304 stainless steel construction mean for corrosion resistance in a typical plumbing system?

The 304 stainless steel body resists rust and general corrosion in potable water and many chemical environments, and the material conforms to ASTM A351 for consistent quality.
