Legend Valve 1-1/2" x 1" Reducing Coupling

This Legend Valve reducing coupling joins a 1-1/2 inch female NPT thread to a 1 inch female NPT thread. It is made from no-lead cast bronze for potable water systems. The fitting suits residential and commercial plumbing installations where a pipe size transition is required.

Threaded NPT limits and lead-free compliance

The FNPT x FNPT connection relies on tapered pipe threads sealed with tape or compound. The no-lead bronze alloy meets California Proposition 65 requirements for drinking water contact. Threaded joints need proper engagement and may loosen under vibration or thermal cycling without regular inspection.

Upgrades from leaded bronze or mismatched bushings

This coupling replaces older leaded-bronze fittings in potable water lines to satisfy current health regulations. It also replaces makeshift reducer bushings that create flow restriction or leak paths. The jump is worth it when a code-compliant, direct size transition is needed.

Questions about this item

What size reducing coupling should I pick for a 1-1/2" to 1" pipe transition?

This coupling is made for a 1-1/2" FNPT connection on one side and a 1" FNPT connection on the other, so it matches that exact step-down.

How does the no-lead cast bronze construction perform in a potable water system?

The no-lead cast bronze body meets Proposition 65 requirements for drinking water, resisting corrosion and providing a durable, leak-free threaded seal.

What does the FNPT x FNPT thread standard mean for installation?

Both ends use female National Pipe Taper threads, so you simply thread the coupling onto male NPT pipe nipples or fittings and tighten for a sealed joint.
