VIP has developed a range of specially formulated EPDM and NBR (Nitrile) compounds to suit modern clay pipe applications, all of which are manufactured in accordance with EN681-1 and meet or exceed the requirements of EN295-1.

Today our clay pipe seals are selected as original equipment by a number of the leading global clay pipe manufacturers are being used in the following applications:

  • Jacking Pipes
  • Pressurised systems (up to 4.5 bar)
  • Non Pressurised (Drainage)
  • Mictotunnels
  • Chemically Resistant installations
  • High temperature resistance
Installing pipes under the road, sewer pipe

We have a number of standard sealing profiles available from our stock range but for those applications where new profiles are required, our team of experienced development engineers are on hand to design, prototype, test and manufacture bespoke gasket solutions.

Clay Pipes

VIP provide a range of seals for jointing vitrified clay pipe from the standard spigot and socket design to seals incorporated into plastic sleeves for jointing straight wall pipe. In addition, we manufacture a range of seal profiles for use within steel collar pipe joints. Moulded seals are available in diameters of up to DN2200 whilst extruded seals can be manufactured to virtually any diameter the client requires.

VIP-Polymers vitrified clay pipe seals are available in diameters of up to 2000mm and can be supplied in numerous elastomeric materials designed to withstand the most demanding drainage applications.


VIPSeal® VIPSeal® is our range of versatile rubber flexible couplings and adaptors wholly manufactured in house and designed for joining and repairing pipes in sewerage, drainage and other non-pressure pipe applications.

We have over 20 years experience of manufacturing these couplings which meet all relevant UK water industry standards.
