  • No-lead bronze protects drinking water safety

  • Cast bronze body resists corrosion and wear
  • California Prop 65 warning for chemical awareness

1" x 3/8" No Lead Reducing Coupling

This threaded coupling joins a 1-inch female pipe thread to a 3/8-inch female pipe thread. It is built for potable water lines where lead-free materials are required by code.

Cast bronze body with FNPT threads

The no-lead cast bronze construction resists corrosion and meets low-lead standards. Both ends use FNPT threads so the fitting threads directly onto male pipe ends without extra adapters.

Replaces older leaded couplings

Use this coupling when upgrading a plumbing system to comply with current no-lead regulations. The step-down from 1 inch to 3/8 inch suits supply branches that need a smaller outlet from a larger main.

Questions about this item

What thread standard does the 1" x 3/8" reducing coupling use, and what does it limit in practice?

The coupling uses FNPT threads on both ends, so it connects directly to matching male NPT pipe or fittings without adapters.

What physical clearance and pipe alignment does the cast bronze reducing coupling need to fit?

It requires enough space for a 1-inch female thread on one side and a 3/8-inch female thread on the other, with straight pipe alignment to avoid stress on the joint.

How is the no-lead reducing coupling installed, and what step do people often get wrong?

Apply thread sealant to the male threads, tighten each side evenly with a wrench, and avoid over-tightening which can crack the bronze casting.
