Matco-norca 25-2000LF Add-a-stop Supply Valve 3/8 Od

Product Description

The MATCO-NORCA 25-2000LF is a quarter-turn straight add-a-stop supply valve designed for retrofit installations on existing supply lines. The valve features a 3/8 inch OD captured nut inlet and a 3/8 inch OD compression outlet, allowing a licensed plumber to add shutoff capability to a line that previously had none. The quarter-turn ball-style operation provides fast, reliable shutoff without multiple handle rotations. The lead-free construction meets current potable water compliance requirements for installations in residential and light commercial settings.

This valve is suited for retrofit plumbing applications where an inline shutoff is needed downstream of an existing angle stop or supply valve. Typical install scenarios include under-sink supply lines serving faucets, toilets, or other fixtures where a secondary isolation point is desired. The straight body configuration keeps the flow path aligned, making it practical in tight cabinet or wall-box spaces. Plumbers and plumbing contractors are the primary installers for this type of fitting.

Key Features

• Quarter-turn operation for quick full open and full closed shutoff
• Retrofit design installs inline on existing 3/8 inch OD supply lines without major rework
• 3/8 inch OD captured nut inlet connection for secure attachment to upstream fitting
• 3/8 inch OD compression outlet for standard supply line or tubing connection
• Lead-free construction meets potable water compliance standards
• Straight body profile suited for space-constrained installations

Compatibility

Designed as an OEM-style retrofit add-a-stop valve for residential and light commercial plumbing supply lines using 3/8 inch OD tubing connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the main water supply and relieve line pressure before beginning any work on supply valves or fittings. Ensure compression fittings are seated properly and hand-tightened before applying a final snug turn with a wrench — do not overtighten compression nuts. Inspect for leaks at both the captured nut and compression connections after restoring water pressure.
