John Guest® PI221212S-US 3/8" x 3/8" Gray Acetal Push-To-Connect Stem Elbow

This John Guest push-to-connect stem elbow creates a 90-degree connection for 3/8-inch tubing in beverage-service and water systems. When a straight connection leaves your line awkwardly routed behind a dispenser or ice machine, its stem-and-socket design helps turn the line where you need it without special installation tools.

Route Lines with a John Guest Push-to-Connect Stem Elbow

Why bar/brewery pros choose this

• 3/8-inch x 3/8-inch connection — Pairs a 3/8-inch stem with a 3/8-inch push-to-connect tubing socket for a compact change in direction.
• Gray acetal body — Corrosion-resistant acetal copolymer construction supports dependable use in water and beverage-service installations.
• Tool-free connection — Insert the stem into a compatible John Guest push-to-connect fitting, then push the tubing fully into the elbow's socket to the tube stop.
• Secure tubing grip — A collet with 301 stainless steel teeth holds the tubing in position while a food-grade nitrile O-ring seals around it.
• Versatile service applications — Suitable for potable water systems such as ice machines, water dispensers, and faucets, as well as air and inert-gas applications including CO2 and nitrogen lines.

Compatibility and fit

The John Guest PI221212S-US push-to-connect stem elbow is for compatible 3/8-inch outside-diameter tubing and a matching 3/8-inch John Guest push-to-connect fitting. The stem end inserts into another fitting; it is not a second tubing socket. Confirm tubing material, operating pressure, temperature, and application requirements before installation. Use compatible plastic or copper tubing, and fully seat each connection before putting the system into service.
