Guest Angle Stop Adptr Vlv, 3/8x3/8x1/4

The John Guest Angle Stop Adapter Valve, 3/8" x 3/8" x 1/4", from Reliance Worldwide Corporation connects directly to your existing stop valve, riser, and water supply line, eliminating the need for an unreliable saddle valve. It is purpose-built for reverse osmosis systems, filtration units, ice makers, and other point-of-use water treatment installations that need a clean, dedicated tap into the cold-water supply.

This adapter installs in the gap between your shut-off valve and supply riser, then provides a dedicated 1/4" push-in tube outlet for your treatment equipment. Built-in features make it both safer and easier to use than the piercing saddle valves it replaces, which are notorious for clogging, restricting flow, and leaking over time. By tying into the existing angle stop instead of puncturing the supply line, you get a far more dependable connection.

Features

• Connection: Male Compression x Female Compression x John Guest Slip tube
• John Guest push-in tube connection for the 1/4" outlet
• Integrated 90-degree shut-off for the branch line
• Swivels for better positioning during installation
• Eliminates the need for a saddle valve entirely
• Corrosion-resistant polypropylene construction

To install, shut off the water and disconnect the supply line from the angle stop. Thread the male compression end into the stop and connect the riser to the female compression end, then push your 1/4" tubing into the slip outlet until it seats. Because the body swivels, you can rotate it to aim the outlet exactly where the tubing needs to go before tightening, which is invaluable in cramped under-sink spaces. The integrated valve lets you shut off the treatment line independently for servicing, so you can change a filter or membrane without disturbing the main fixture. For a clean, reliable tap into your cold-water supply, this John Guest angle stop adapter valve is the professional alternative to piercing saddle valves.

Compared with a saddle valve, this adapter offers a permanent, full-flow connection that will not clog the small piercing hole saddle valves rely on, a common cause of weak RO production over time. It is the connection method most plumbers recommend for new installations, and retrofitting it in place of a failing saddle valve is a frequent and worthwhile upgrade for any point-of-use system.
