316 Stainless Steel Hex Bushing

The Legend Valve 416-511 is a 316 stainless steel hex bushing with FNPT by MNPT threads. It connects a three-inch female pipe thread to a two-and-a-half-inch male pipe thread in industrial piping systems. The material resists corrosion in demanding fluid-handling applications. California Proposition 65 warnings apply to this product.

Installers reducing from three-inch

This bushing suits pipefitters and maintenance crews who need to step down from a three-inch female NPT connection to a two-and-a-half-inch male NPT connection using 316 stainless steel. It is not for installers working with different thread standards, different size transitions, or materials other than 316 stainless steel. Buyers requiring other alloys or thread types should look elsewhere.

316 stainless steel material grade

The single specification that decides fit is the 316 stainless steel construction, which determines chemical compatibility and corrosion resistance in the intended service. Confirm the media and environment are suitable for this alloy before installation. The hex profile allows standard wrench engagement for assembly.

Questions about this item

What thread sizes does the 3 in x 2-1/2 in 316 stainless steel hex bushing connect?

The bushing has a 3 inch female NPT inlet and a 2-1/2 inch male NPT outlet, reducing the pipe size directly at the fitting.

How do I install the hex bushing without damaging the 316 stainless threads?

Apply PTFE tape or pipe dope to the male threads only, then tighten with a wrench on the hex flats until the joint feels firm; over-tightening can gall stainless steel.

When should I replace the 316 stainless steel hex bushing in a corrosive system?

Inspect annually for pitting, cracking or thread deformation; replace immediately if any wall loss or leakage appears at the joint.
