Rubber Gaskets & Seals

Bespoke Rubber Mouldings

At Coruba, we create bespoke rubber gaskets and rubber seals in a range of rubber compounds. By creating bespoke gaskets from custom designs, you can be sure each part is created first time to fit your requirements.

With extensive knowledge in our craft and over 100 years’ experience between our directors, we are the perfect choice to create your custom gaskets. When we say custom, we mean custom. We will create gaskets and seals using your designs, offering advice on the material according to your application. Simply give us a call or email us and one of our experts will walk you through the simple process of finding your perfect gaskets.

Using a custom-cut design, gaskets are 2D products made of sheeting, based on your requirements. If you wish to have a 3D product created using bespoke moulds, please visit our rubber mouldings page.

From our wide range of over 10 materials, you can choose one that suits your applications. Each material has differing resistances and common uses. Read through our list below for a quick guide to just a few of the options.

Bespoke Cut Gasket Materials by Polymer Type

  • Economy Grade Rubber (SBR, Nitrile, Neoprene, EPDM)
    Economy Grade Rubber (SBR, Nitrile, Neoprene, EPDM) Gaskets

  • Ethylene Propylene (EPDM)

    An incredibly versatile rubber, with sheets available as FDA approved, Flame Retardant and KTW approved for potable water.

  • Nitrile

    Offering good to excellent resistance to oil, fuel and certain chemicals, Nitrile is also available as FDA approved. We also offer other economy grade materials – please check our price list for the full range of economy grade materials.

  • Silicone

    Commonly used in applications involving food and drink, Silicone is operational at extreme temperatures and has very good ageing and weather characteristics.

  • Neoprene

    Good chemical resistance and flexibility over a broad temperature range. Available as FDA approved and fire retardant to NFF16-101 M2-F3 & UL94-VO.

  • Viton®

    Our FKM range is made from genuine Viton®. Available in DuPont A and B grade and FDA approved, it has outstanding resistance to chemicals, acids, oils and petroleum products at high temperatures. A superb compound.

  • Cork

    Neoprene/Nitrile bonded cork sheets offer excellent resistance to transformer oils and fuels. They have high compression, resilience and flexibility characteristics.

  • SBR

    Styrene Butadiene Rubber is a general purpose material, used for a range of applications. Resistant to tearing, ozone and inorganic chemicals, it is ideal for automotive and construction industries.

  • Fabric Reinforced

    Our fabric reinforced sheeting offers greater tensile strength and tear resistance than normal rubber sheeting, making it a fantastic gasket or seal material for a range of applications.

  • PVC

    Flexible clear PVC sheeting has excellent oil, fuel and grease resistance. It boasts excellent resilient properties and is regarded as a highly durable material.

  • Sponge & Foam

    We offer a range of sponge products that include closed cell sheeting with minimal water retention and thermal insulating sponge sheeting with a Class 0 Fire Rating, as per BS476 part 6/7.
