Larsen Supply Co. 03-1807 Slip Joint Nut Kit 1/2 Fpt X 1/2 Od

Product Description

The LARSEN SUPPLY CO., INC. 03-1807 is a slip joint nut kit designed to connect old-style metal faucet supply tubes to standard plumbing fittings. The kit covers a 1/2 inch female pipe thread (FPT) inlet mating to a 1/2 inch OD tube. It ships with a cone washer and friction ring, giving the installer all hardware needed to complete a leak-free slip joint connection in a single package. Licensed plumbers and experienced service techs use this kit when repairing or replacing legacy metal supply tube connections at faucet shutoff valves under sinks and lavatories.

This kit is suited for residential and light commercial plumbing service work where older-style rigid metal faucet supply tubes are still in place. The 1/2 inch FPT x 1/2 inch OD configuration matches the thread and tube sizing common on traditional under-sink supply runs. The included cone washer and friction ring allow for proper seating and compression at the slip joint without the need for additional sealing components. Plumbers stocking service vehicles will find the six-piece package quantity practical for repeat call volume.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the water supply at the isolation valve or main before beginning work and relieve line pressure before disconnecting any existing fittings. Hand-tighten the slip joint nut onto the FPT fitting first, then snug with pliers — avoid over-tightening, which can crack the nut or distort the cone washer seat. Verify no leaks at operating pressure before closing up the cabinet.
