Oatey 4794PCLKLF Quarter Turn Angle Stop Valve

Product Description

The OATEY 4794PCLKLF is a quarter turn angle stop valve designed for residential and light commercial plumbing supply line connections. This lead-free valve features a 1/2 inch nominal sweat inlet and a 3/8 inch OD compression outlet, with a 5-inch extension body that provides clearance in tight installations. The quarter turn ball-style mechanism delivers fast, positive shutoff without multiple handle rotations. A loose key operation limits unauthorized access to the valve, making it well suited for commercial restrooms, multi-unit residential buildings, and any application where controlled access to individual fixture shutoffs is required. Licensed plumbers are the primary installers of this fitting.

This angle stop valve is used to isolate water supply to individual fixtures such as lavatories, toilets, and similar plumbing fixtures. The sweat inlet requires a soldered copper connection to the supply stub-out, while the 3/8 inch OD compression outlet connects directly to standard braided or rigid supply lines. The extended body accommodates wall depth variations common in remodel work and new construction framing. The loose key feature means the valve can only be operated with the accompanying removable key, restricting use to authorized personnel in public or semi-public spaces.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the main water supply and depressurize the line before soldering the sweat inlet connection. Allow the fitting to cool completely before pressure-testing the joint, and do not apply heat near the valve body or compression outlet. Confirm that the compression ferrule and nut are properly seated before restoring water supply.
