VIP-Polymers have for a number of years developed and manufactured a range of sealing gaskets for pipe fittings and repair clamps used on a variety of applications:

Waffle pattern repair mat VIP Polymers  

  • End load restraint systems
  • Repair couplings
  • Repair clamps
    (using “waffle pattern” repair mats)
  • Stepped couplings
  • Flange adaptors
  • Dismantling joints
  • Shoulder couplings
  • Gripper couplings

With an advanced rubber to metal bonding facility available in-house, we can also offer reinforced repair mats incorporating components made from stainless steel, lead, aluminium, copper and iron. Large compression and injection moulding presses enable us to offer components up to 2.4 metres wide whilst our extrusion facility enables us to produce profiles of up to 300mm width.

Many of the compounds we use to manufacture repair clamp gaskets hold multi-region potable water approvals. This means our customers enjoy the benefits of reduced inventory as stocks of gaskets for different global regions are no longer necessary.
