1-1/4" NL F1807 PEX x Insert Adapter

This brass adapter connects 1-1/4 inch F1807 PEX tubing to an insert fitting in potable water systems. It is manufactured by Legend Valve and supplied new for residential and commercial plumbing installations. The no-lead construction meets current drinking-water safety requirements.

Installer fit and system constraints

Plumbers working with 1-1/4 inch F1807 PEX who need a direct transition to insert-style connections will find this part suitable. It is not intended for press, crimp, push-fit or expansion PEX systems, nor for gas, fuel or hydronic applications that require different approvals. Buyers needing a different tubing size or connection type should select an alternative fitting.

Build integration and compliance

The adapter joins the PEX line to an insert fitting using standard crimp tools and rings, completing the joint without soldering or threading. Its no-lead brass body satisfies California Proposition 65 warnings for cancer and reproductive harm, so installers must follow local code for lead-free verification. No additional components are included beyond the adapter itself.

Questions about this item

What PEX tubing size is required for the F1807 connection on this adapter?

The adapter is sized for 1-1/4" PEX tubing using the F1807 crimp or clamp connection method.

Can this no-lead brass adapter join directly to older leaded-brass insert fittings in an existing system?

Yes, the insert end accepts standard 1-1/4" PEX tubing sizes, so it will connect to legacy insert fittings already in place.

How can I verify the F1807 crimp joint is watertight after installation?

Pressurise the line and inspect the crimp ring with a go/no-go gauge; a passing gauge reading confirms a proper seal.
