VIP-Heinke moulds dual hardness Tyton® gaskets specifically for iron pipe in sizes DN80 through DN2000. The Tyton® joint is a standard push-fit, flexible joint for water pipelines offering a high performance joint with a number of benefits. Quick and easy to install. Capable of angular deflection and longitudinal withdrawal without loss of performance. Dual hardness gaskets in sizes greater than 2000mm are also manufactured by a recently developed special moulding and joining procedure. VIP-Heinke has also developed and patented its own design of seal for push-fit flexible joints for iron pipe known as Viptyte. This is a specially profiled seal of single hardness rubber and is designed to be incorporated into the same socket design as used for the Tyton® gaskets.

These values are also based on Class K9 centrifugally cast pipes. Anchored Push-Fit Flexible Joints: These are self anchored joints which eliminate the need for thrust blocks at changes in direction, making them particularly suitable for difficult or unsuitable ground conditions such as soft ground or subsidence areas, where space is limited, steep inclines, under rivers and lakes and above ground pipelines. The gasket used in this joint system is a locked-in gasket which is a Tyton® seal incorporating metal teeth which lock into the body of the pipe.
