Reducing Coupling for Industrial Plumbing

This Legend Valve 416-389 is a 316 stainless steel reducing coupling designed for industrial plumbing applications. It connects piping systems using female NPT threads on both ends. The component is supplied new and ships directly from the manufacturer. It suits maintenance engineers and pipefitters joining dissimilar pipe sizes.

316 Stainless Steel FNPT Thread Specification

The single specification that decides fit is the 316 stainless steel construction with FNPT x FNPT threading in a 2 in x 3/4 in configuration. This material grade offers corrosion resistance for demanding fluid handling. The thread standard and size combination must match the existing piping exactly. No other dimensions or pressure ratings are provided in the data.

Installation Notes and Common Issues

Installation requires standard pipe thread sealant or tape compatible with stainless steel to prevent galling and ensure a leak-free seal. Proper alignment is critical when joining the two different nominal sizes. A common issue is cross-threading or over-tightening, which can damage the female threads. California Proposition 65 warnings apply regarding chemical exposure.

Questions about this item

How does the 2 in by 3/4 in size affect flow when the coupling is installed in a pipe run?

The reducing coupling connects a 2-inch female NPT thread to a 3/4-inch female NPT thread, so flow transitions from the larger to the smaller bore at the joint.

What does the FNPT x FNPT designation mean for sealing and compatibility with other fittings?

Both ends have female National Pipe Taper threads, so each side accepts a male NPT fitting and seals on the thread taper when tightened with sealant or tape.

What are the physical dimensions and material requirements for mounting this 316 stainless steel coupling?

The body is 316 stainless steel with female NPT threads on both ends; it threads directly onto matching male NPT pipe or nipples without separate mounting hardware.
