TYTON® Gasket Fittings / Flanged Fittings
The tightness of the TYTON® Gasket is generated by means of deformation caused by the water pressure. The TYTON® Gasket, generally in EPDM or NBR, is located inside the socket of the element where the spigot of the adjacent element is inserted. It is in between the socket and the spigot. The back side of the TYTON® Gasket is the softer side. Tightness is based on the principle of “the greater the pressure, the greater the sealing”.
The flange gasket generates watertightness by deformation of a flat gasket located between the flat surfaces of two flanges that is tightened by screws.

Lok&Play Locked Accessories
The socket has two chambers, the first one lodges the Tyton® gasket, which makes the joint watertight. The second chamber has a window (or several, depending on the diameter) over which the locking segments are inserted once the end of the tube is plugged in; these provide a positive axial seal between the inside surface of the socket and the locking cord at the smooth end of the pipe.
