John Guest Push-Fit Stop Valve - 1/4 Inch Water Filter Shutoff Valve

For anyone with a water filtration system or ice maker, this John Guest stop valve is a simple but essential component. It's designed for 1/4 inch tubing connections and uses their famous push-fit system that requires no tools for installation - just push the tube in, and it locks securely. The valve has a rotating handle that controls water flow, making it easy to shut off water to your filter for maintenance or replacement. It's NSF 51 and 62 certified with FDA-approved materials, so you know it's safe for drinking water applications. I've used these in several under-sink filter installations, and they've never leaked or failed. The quality is typical John Guest - reliable, durable, and easy to work with. The push-fit connections save so much time compared to compression fittings or other connection methods. Whether you're installing a new water filter, repairing an existing system, or adding a shutoff for your refrigerator ice maker, this valve makes the job straightforward. The compact size fits in tight spaces under sinks or behind appliances. If you're DIY-inclined and comfortable working with water lines, this is a professional-grade component that will make your life easier. Just make sure you have the correct tubing size (1/4 inch OD) and that you cut the tube cleanly for a proper seal.
