John Guest 10 mm tube to 3/8" stem converter

Adapter designed to create a transition between a 10 mm metric tube line and a smooth 3/8" stem.

Application

Allows components with an imperial stem to be integrated into installations using metric tube, avoiding improvised solutions or forced connections.

Selection

Confirm that the tubing has a 10 mm outside diameter and that the interface on the other component is a smooth 3/8" stem.

Installation

Depressurize the system, prepare the 10 mm tube with a square cut, and check that the stem is clean and undamaged. Install without tension and verify leak tightness.
