20pcs Stop Valves 1/2 in PTC 3/8 in Angle Stop Valve - Pack for Home

In this review the 20pcs stop valves pack is judged by its use as a reliable shutoff solution for residential and light commercial plumbing. The main reason to buy is straightforward: the set provides twenty chrome plated brass angle stop valves with a 1/2 in push-to-connect inlet and a 3/8 in OD compression outlet, making bulk replacements and project installs fast and consistent. Installers and DIYers will appreciate that these valves are certified for drinking water, simple to connect without special tools, and offer a full 1/4 turn on/off for quick service.

Key Features

• Package quantity: Twenty valves in one pack provide consistent parts for multi-fixture jobs or stocking a service van.
• Materials and finish: Chrome plated brass body with an ABS handle offers corrosion resistance and a finish that matches most faucets and fixtures.
• Push-to-connect inlet: The 1/2 in PTC inlet fits PEX, CPVC, PE-RT, SDR-9 HDPE and copper pipe for fast tool-free connections.
• Compression outlet: The 3/8 in OD compression output accepts 3/8 in braided supply lines and copper pipe commonly used on sinks and toilets.
• Operation and safety: The 1/4 turn operation gives quick shutoff and the valves are certified to NSF/ANSI 61 and UPC for drinking water use.
• Easy install: No soldering, gluing, or crimping required so the valves can be fitted even on wet lines to save time on repairs.

Who It's For

The 20pcs stop valves pack is aimed at plumbers, property managers, and serious DIYers who need uniform, reliable shutoff valves for multiple fixtures-kitchen sinks, bathroom faucets, and toilets-or who maintain RV and touring vehicle plumbing. The bulk pack is especially useful when replacing several valves at once or keeping spares on hand for quick service calls.

Those who only need a single spare valve or who require a different inlet or outlet size should look elsewhere; this pack is optimized for jobs requiring many valves in the specific 1/2 in PTC to 3/8 in compression configuration.
