IRON PIPE SEALS Moulded Seals available for pipes up to 2000mm Diameter Extruded and joined seals beyond 2000mm Both Metric and Imperial sizes available

VIP-Polymers - The world's largest manufacturer of Tyton® Gaskets

VIP-Polymers mould dual hardness Tyton® gaskets for Ductile Iron pipe in sizes from DN80 to DN2000.

The Tyton® joint is a standard p ush-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 manufactured by a moulding and joining procedure.

VIP-Polymers have 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.

Please note that these values are for guidance only and may vary depending upon manufacturer of the iron pipe. 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-prone areas; where space is limited; steep inclines; under rivers 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. Tyton® Sit seals can accommodate angular deflection and longitudinal withdrawal without loss of performance.

VIP-Polymers also manufactures and supplies gaskets to other iron pipe joint configurations including mechanical flexible joints, anchored mechanical flexible joints and flange joints.

Mechanical Flexible Joints:

Designed primarily for the gas market, these seals incorporate a specially formulated nylon tip, while the base of the seal has a bonded backing tape to create an integral seal. For water applications, an all-rubber seal can be used. These rings are available in sizes of up to 1600mm.

VIPtyte™ Iron Pipe Seals:

The Viptyte™ is a patented gasket designed for application in the same joint design uses a standard Tyton® gasket. The design of the seal acts as a compression seal and also employs a lip seal to provide a more secure sealing force as the internal pressure within the pipe increases. This unique seal design can be manufactured in either single or dual hardness as per the current Tyton® seal design.
