Lead-Free Bronze Bushing

This Legend Valve hex bushing connects a 2-1/2 inch male NPT thread to a 1 inch female NPT thread in potable water systems. The no-lead cast bronze construction satisfies California Proposition 65 requirements for drinking water installations. It provides a durable, corrosion-resistant transition between different pipe sizes.

Suitable for potable water plumbing

Installers working on lead-free water supply lines can use this fitting to reduce pipe diameter at a threaded joint. It is not intended for gas distribution, high-pressure hydraulic systems, or applications requiring a compression or push-fit connection. Buyers needing a different thread standard or a larger size reduction should select another fitting.

2-1/2 inch MNPT to 1 inch FNPT

The defining specification is the thread pairing: a 2-1/2 inch male NPT end and a 1 inch female NPT end. Matching these exact threads to the existing pipework determines whether this bushing will seal correctly. Verify both thread sizes and the NPT standard before purchase.

Questions about this item

Which Legend Valve hex bushing size should I select for a 2-1/2 inch male pipe thread reducing to a 1 inch female pipe thread?

The 310-497NL model is a no-lead cast bronze hex bushing with 2-1/2 inch MNPT and 1 inch FNPT threads, designed for that exact reduction in potable water systems.

What does the no-lead cast bronze construction mean for daily plumbing use?

The no-lead bronze meets low-lead requirements for drinking water installations, while the cast bronze body resists corrosion and handles typical residential and commercial water pressures.

How does the NPT thread standard affect sealing on this bushing?

NPT tapered threads create a mechanical seal when tightened, so applying thread sealant or tape on the male threads ensures a leak-free joint on both the 2-1/2 inch and 1 inch ends.
