Rubber Seals & Gaskets

Rubber seals and gaskets can be manufactured in many different materials and choosing the correct material is extremely important. This of course depends on the environment and end use of the assembly and the level of seal that is specified by our customer.

Although Rubbertech is primarily a silicone moulding company we will manufacture in other rubber materials if the product demands, such as Neoprene, Nitrile, EPDM, Fluorosilicone and TPE materials.

The materials and suppliers that we use mean that we can offer rubber seals with many specific properties, such as:

  • Medical class approved
  • Food Safe approved
  • Flame Retardant materials approved to UL standards
  • Conductive
  • High and Low temperature ranges
  • Steam Sterilization Resistant
  • RF screening grades
  • ATEX approved
  • Pantone and RAL colour matched
  • Anti-bacterial additive

If a rubber seal is required as an assembly to metal or specific plastics including PTFE then we can over mould these two materials to form a better seal and reduce assembly costs for our customers.

Rubbertech can also supply rubber gaskets and seals produced by extrusion methods; these are either supplied in lengths to specific cross section or can be joined after extrusion to form a complete unbroken seal.

If the seal has a flat profile then these can be supplied punched from sheet, punched gaskets can be supplied in silicone, EPDM, Nitrile and various sponge grades all if necessary with adhesive backing for assembly.

All of these methods require tooling and can range from low cost for punch tools and extrusion tools to higher costing compression and injection tools. The best method is ultimately decided by the design of the part and the estimated quantities required.

Rubbertech have excellent relationships with material suppliers and toolmakers, this enables us to offer prompt service, value and flexibility regardless of how large or small the enquiry may be.
