Self-Anchoring Sealing Gasket
Self-anchoring push-on gaskets have proven to be an extremely successful, trouble-free means of joint restraint for Ductile Iron Pipe. These are patented gaskets that contain high-strength stainless steel elements spaced around the gasket that develop a dependable gripping action. Because of the wedging design, the force between the spigot and the socket of the pipe joint is essentially constant at any given pressure thrust regardless of the tightness or looseness of the joint fit or the joint deflection.
These push-on Self-anchoring gaskets are available for DN80 through DN800 Ductile Iron Pipe.
