1-1/4" No Lead Bronze Insert Coupling

The Legend Valve 312-166NL is a 1-1/4 inch bronze insert coupling manufactured with no-lead material for potable water plumbing. It connects two sections of compatible piping in residential or commercial supply lines. This new fitting meets the requirements for lead-free installations in applicable jurisdictions.

Sustained pressure performance

The bronze construction resists corrosion and handles continuous water pressure typical of domestic supply systems without degradation. No-lead alloy maintains structural integrity under constant load and thermal cycling from seasonal temperature changes. The coupling provides a reliable joint for long-term service in pressure applications.

Installation practicalities

The insert design requires barbed ends to be secured inside the pipe with appropriate clamps or crimp rings for a watertight seal. Installers must verify the pipe inside diameter matches the 1-1/4 inch coupling size before assembly. California Proposition 65 warnings indicate the product contains chemicals known to cause cancer and reproductive harm, so handling precautions are advised.

Questions about this item

Does the 312-166NL coupling generate any noise or heat when water runs through it continuously?

The bronze insert coupling is a passive fitting with no moving parts, so it produces no operational noise or heat during continuous water flow.

What pipe size and type must I already have for the 1-1/4 inch Legend Valve 312-166NL to connect properly?

You need 1-1/4 inch tubing or pipe with an inside diameter that accepts a standard bronze insert barb for a secure press-fit connection.

Will the no-lead bronze 312-166NL corrode or react if I join it to older copper or galvanised plumbing?

No-lead bronze is compatible with copper and galvanised systems; use dielectric unions if dissimilar metals must be joined to prevent galvanic corrosion.
