John Guest 3/8" × 1/4 MFL male adapter

Fitting to connect 3/8" (9.5 mm) tube to a 1/4 MFL connection. It is a compact solution for integrating push-fit tubing with dispensing components that use this standard.

Compatibility

Check that the component is actually 1/4 MFL and that the line is 3/8". MFL and FFL describe different complementary connections and must not be confused with NPTF or BSP.

Installation

Work with the system depressurised, cut the tube square, insert it fully and connect the threaded part in alignment. Check for leaks before operating.

Maintenance

Check the tube end when disassembling and avoid reusing sections that are marked or deformed.
