COMPATIBILITY
What This Valve Works With
This John Guest inline ball valve is designed exclusively for potable water applications and other compatible potable liquids. The polypropylene construction offers high chemical resistance suitable for reverse osmosis systems, water filtration setups, and drinking water lines. Do not use this valve with compressed air, inert gases, explosive gases, petroleum spirits, other fuels, or heating systems, as the materials are not rated for those applications.
🔧 Pro tip: Before making your first connection, practice the push-and-pull motion with a scrap piece of tubing. You'll quickly learn the feel of a proper connection, which should be firm and require deliberate force to seat fully.
