The John Guest Reducer Stem-Tube 3/8” × 5/16” is a product that is made to reduce the size of your tubing in a simple way while still holding a secure, leak-free connection. By using JG Push-Fit technology, the installation is fast and can be done without any tool—just put the stem into any JG push-fit fitting that is compatible.
Made of sturdy gray acetal and equipped with a food-grade nitrile O-ring, this reducer is great for potable liquids, beverage dispensing, and water applications.
