Legend Valve

Legend Valve 404-507 3" x 1" 304 Stainless Steel Hex Bushing

SKU CH-Q2EG-N7HBH

304 stainless steel hex bushing reduces a 3" female NPT thread to a 1" male NPT thread for corrosion-resistant piping connections

  • 304 stainless steel resists corrosion
  • Hex design allows wrench tightening
  • 3 inch by 1 inch size fits piping systems
  • FNPT to MNPT threads connect different fittings
  • California Proposition 65 warning applies

Purpose & Fit

This 304 stainless steel hex bushing reduces a 3-inch female NPT opening to a 1-inch male NPT thread. It is intended for plumbing professionals and maintenance teams who need a corrosion-resistant transition in water, oil or gas lines. Buyers who require a different reduction ratio or a non-NPT thread standard will not find a match here.

Pressure & Flow

The fitting is machined from 304 stainless steel, so it resists rust and chemical attack under normal service pressures. Its hex profile allows a secure wrench grip without damaging the body, and the smooth internal bore minimises turbulence. No pressure rating or temperature limit is supplied, so engineers must verify suitability against system specifications.

Installation Reality

Male and female NPT threads seal with tape or compound, so installers should plan for thread engagement time on each joint. The hex flats provide a single-tool tightening point, but the 3-inch to 1-inch step means the assembly will be heavier on one side and may need pipe support. California Proposition 65 warnings apply to this product.

Questions about this item

How do I install the 304 stainless hex bushing without cross-threading the FNPT and MNPT threads?

Clean both FNPT and MNPT threads, apply PTFE tape or pipe dope to the male threads only, hand-tighten the bushing into the female port, then finish with a wrench on the hex flats for one to two turns; the step most people skip is cleaning the female threads first.

What maintenance will the 304 stainless hex bushing need over time?

Inspect the joint annually for leaks or corrosion; reapply thread sealant if seepage appears, and replace the bushing if the hex flats deform or the 304 stainless shows pitting.

What is the first limit that appears under sustained pressure and temperature cycling?

The 304 stainless material and FNPT x MNPT thread engagement will reach their pressure-temperature rating before the hex flats yield, so sustained cycling will show leakage at the thread seal first.
