Tubing Connectors
The Culligan Water Tower drinking water system features easy-to-use push-in tubing connectors
(Figure 3). Fittings consist of two parts: a body and a colored collet. Collet color corresponds to
tubing color to be used at that connection (Figure 3A).
1. To install a tube, lubricate the tubing end with water (only) and push it through collet
until it seats firmly at bottom of fitting (Figure 3B). You should feel the tubing pass
the O-rings. Cut ends must be square. Be sure the tubing is smooth and free of abrasions,
otherwise a leak may result. Cut tubing only with a new razor blade.
2. To remove a tube, push and hold the collet against the fitting body and pull the tube
from the fitting. (Figure 3C).
