John Guest (JG) WaterMark Stem Tee – 12mm Push-On Fitting
This is a John Guest Watermark certified Speedfit Twist & Lock 12mm Stem Tee. The stem fitting can be coupled with push-on fittings to create custom fittings as required.
It can be used on the standard John Guest Speedfit tubing (LLDPE) and the Watermark 12mm tubing (BPEX). Ensure you use the matching pipe inserts with each style tubing, i.e. DO NOT use Watermark inserts with standard John Guest Speedfit tubing (LLDPE).
Simply push the fitting fully onto the pipe and twist the plastic nut clockwise to lock in place. Should the need arise to demount the connection, unlock the nut, push the collet towards the body of the fitting and pull the pipe to release.

- Approved fitting for caravan manufacturing
- Watermark certified for use on hot water over 90 °C
