COMPATIBILITY
Works With John Guest and Universal 1/2-Inch Tubing
The PEI222020 is compatible with all John Guest 1/2-inch OD tubing and most universal 1/2-inch tubing used in residential and light commercial water filtration systems. This fitting works with reverse osmosis systems, inline filters, icemakers, and refrigerator water lines that require a 90-degree directional change at the 1/2-inch connection point.
🔧 Pro tip: Mark the insertion depth on your tubing with a felt pen before pushing it in. This lets you visually confirm full seating without relying on feel alone, especially in cramped under-sink installations where you cannot see the connection point clearly.
