SKU CH-7N13-PDN53

A 1-inch bronze male adapter for connecting cast bronze insert to MNPT threads

  • 1-inch bronze adapter connects copper to male NPT threads
  • Cast bronze construction resists corrosion in plumbing systems
  • Lead-free compliant alloy meets California Proposition 65 standards
  • Precision machined threads ensure leak-free joint integrity
  • Compact fitting simplifies installation in tight supply lines

1" Bronze Male Adapter

This 1" cast bronze adapter connects a male NPT thread to a bronze insert for plumbing installations. It suits installers joining threaded pipe to a bronze fitting in water or gas systems. The part is new and supplied by Legend Valve under model 312-005. Buyers who need a female-threaded adapter or a different pipe diameter cannot use this fitting.

Thermals noise and power draw

As a passive bronze fitting the adapter generates no heat, produces no noise and draws no power during normal operation. It simply provides a mechanical seal between threaded components without any moving parts or electrical requirements. Performance depends entirely on correct thread engagement and appropriate sealant applied by the installer.

Proposition 65 notice and shipping

The product carries a California Proposition 65 warning because it contains a chemical known to the state to cause cancer and birth defects or other reproductive harm. Orders of $75 or more qualify for free shipping direct from the manufacturer. No additional accessories or software are bundled with this fitting.

Questions about this item

How do I install the 1 inch bronze male adapter without damaging the threads?

Wrap the MNPT threads with PTFE tape or pipe thread sealant, then hand-tighten the adapter into the female fitting before using a wrench for a final quarter turn; over-tightening can crack the cast bronze body.

What maintenance will the bronze adapter need after installation?

Inspect the joint annually for green corrosion or seepage; if leakage appears, disassemble, clean the threads, apply fresh sealant and re-tighten — no scheduled replacement is required for the bronze material itself.

What is the first limit I will hit if the adapter sees continuous high-pressure water flow?

The cast bronze insert and MNPT threads are rated for standard plumbing pressures; sustained pressure spikes above the system design limit will cause thread deformation or body stress before the bronze material itself fails.
