Legend Valve 416-505 316 Stainless Steel Hex Bushing 2-1/2 x 1-1/2

SKU CH-4YKD-H3JY7

316 stainless steel hex bushing reduces a 2-1/2 inch female pipe thread to a 1-1/2 inch male thread for corrosion-resistant piping

  • 316 stainless steel resists corrosion in harsh environments
  • Hex head design allows secure tightening with standard tools
  • Reduces 2-1/2 inch to 1-1/2 inch pipe threads
  • FNPT to MNPT configuration connects female to male fittings
  • California Proposition 65 warning applies to this product

Industrial Plumbing Reducer

The Legend Valve 416-505 is a 316 stainless steel hex bushing designed to connect 2-1/2 inch female NPT threads to 1-1/2 inch male NPT threads. It suits industrial piping systems that require corrosion-resistant transitions between different pipe sizes. Buyers needing push-fit or compression connections cannot use this threaded fitting.

California Proposition 65 Compliance

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm, as identified under Proposition 65. The 316 stainless steel construction provides inherent resistance to chemical attack in normal service environments. No thermal, noise or power-draw characteristics apply to this passive mechanical component.

Sustained Pressure Service

Under continuous system pressure the hex bushing maintains a sealed joint without degradation from fluid contact. The stainless alloy resists scaling and pitting that would compromise the thread engagement over time. Installers should verify the pressure rating matches the system design before assembly.

Questions about this item

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

Apply PTFE tape or pipe dope to the male NPT threads, then tighten with a hex wrench on the bushing flats until snug — over-tightening the 2-1/2" female side is the common mistake that distorts the threads.

What maintenance will the 316 stainless steel hex bushing need over time?

Inspect the FNPT and MNPT joint annually for corrosion or seepage; reapply thread sealant if any weep appears — the 316 alloy resists most chemicals but galvanic action with dissimilar metals can accelerate wear.

What pressure or temperature limit shows up first during sustained service?

The NPT thread seal typically reaches its pressure-temperature rating before the 316 stainless body yields, so sustained duty is limited by the thread sealant and joint integrity rather than the bushing material itself.
