J-Flex – for custom made, precision engineered die cut gaskets in premium grade elastomers.

J-Flex is the comprehensive source for all your die cut gaskets requirements, whether you need small, medium or large volumes. Whatever your requirements, we can help with a superb range of die cut rubber gaskets.

Our press cutting of gaskets and geometric shapes are generally in soft engineering, non-metallic materials – including:

  • Natural and Synthetic Rubbers
  • Rubber Insertions and Diaphragm Materials
  • Non-Asbestos Jointings
  • Vulcanised Fibre
  • Bonded Cork
  • P.T.F.E. (Polytetrafluoroethylene)
  • Felt
  • Ceramic Papers and Jointings
  • Silicone gaskets
  • Viton™ gaskets
  • By using non-metallic materials, our die cut rubber gaskets are anti-corrosion gaskets as standard.

Whatever the size of gasket you require, we can usually help. Gaskets beyond the scope of press cutting, due to size, are hand fabricated in segments with bonded joints.

In addition we supply large Vulcanised ‘O’ Rings; Boiler Joints; Packings and Corrugated Metal Gaskets.

Water jet and large digital flatbed cutting production methods are also used where appropriate.

All can be made to your specific requirements quickly and efficiently.
