Oatey 4790PCLKBG Quarter Turn Angle Stop 5/8 X 3/8 Inch

Product Description

The OATEY 4790PCLKBG is a quarter turn angle stop valve designed for residential and light commercial plumbing supply lines. It features a 5/8 inch OD compression inlet sized for 1/2 inch copper supply pipe and a 3/8 inch OD compression outlet for connecting fixture supply lines. The valve operates with a quarter turn of the loose key handle, allowing a licensed plumber to open or shut off water supply quickly without a full rotation. This style of stop valve is a standard fitting at toilet, lavatory, and kitchen sink installations where an under-counter shutoff is required.

This angle stop is suited for under-sink and toilet rough-in applications in residential construction and remodel work. The 90-degree body orientation routes the supply line from a wall stub-out to a vertical fixture supply tube. The loose key design requires a key or flat tool to operate, which limits unauthorized tampering with the valve. It is installed by a licensed plumber as part of fixture trim-out and is appropriate for potable cold water supply lines in finished spaces.

Key Features

• Quarter turn operation for fast open and close without a full-rotation handle
• 5/8 inch OD inlet compatible with 1/2 inch copper supply pipe
• 3/8 inch OD compression outlet for standard fixture supply lines
• Angle body configuration routes supply from wall stub-out to fixture
• Loose key handle deters unauthorized valve operation

Compatibility

Designed as an OEM-style replacement or new-installation angle stop for residential and light commercial plumbing fixtures served by 1/2 inch copper supply pipe with 3/8 inch OD compression outlet connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off the main water supply and depressurize the line before removing or installing any stop valve. Compression fittings must be seated squarely and tightened to manufacturer guidance without over-torquing, which can crack ferrules. Inspect for leaks at both compression connections after restoring water pressure.
