  2. Push 1/4 inch tubing firmly into the push-fit end of the CI450814FW adaptor until it reaches the internal tube stop
  3. Wrap 1/2 inch BSP male threads with 2-3 wraps of PTFE tape, then thread into the female adaptor hand-tight plus 1-2 turns with a wrench
  4. Pressurize the system slowly and check all connections for leaks before putting into full service
COMPATIBILITY

System Integration

The John Guest Speedfit CI450814FW adaptor works with all standard 1/4 inch OD tubing used in reverse osmosis and water filtration systems, including polyethylene, nylon, and LLDPE materials. The 1/2 inch BSP female thread connects to faucets, tank valves, feed water adapters, and other threaded components commonly found in residential and light commercial water treatment installations. This adaptor is suitable for cold water applications up to 65°C and pressures up to 150 PSI, making it compatible with Isopure Water RO systems and most major filtration brands.

🔧 Pro tip: Keep the collet and O-ring clean when making connections. If you need to disconnect, push the collet ring toward the body while pulling the tube out—never just yank the tubing, as this can damage the internal grip mechanism and lead to slow leaks over time.
