Viton Sponge Seals

Viton Sponge Seals

Viton Sponge Seal: Advanced Seals & Gaskets take great pride in producing some of the highest quality seals in the UK from a range of materials, taking the form of gaskets, washers, O-rings, cord and extrusions, which are all designed for the purpose of preventing leaks or ingress of air, fluids and gas.

One such material is Viton sponge, which has been specially formulated to resist extreme temperatures ranging between -25°C to +204°C, and a vast number of chemicals, liquids and acids. All our Viton sponge seals are made to order and are based on samples or drawings provided by customers to ensure the final product perfectly fits the application. 

As each form of seal needs to be manufactured using a different process, ASG has invested heavily in various machinery meaning we can produce both high and low volume Viton sponge seals, designed for use with sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration.

What are Viton Sponge Seals?

Viton sponge is one of many closed-cell materials on offer from Advanced Seals & Gaskets, which is used where a high-performance sponge is required for extreme environments.  Viton sponge seals are a device or substrate that is used to join surfaces together to either act as a separator or a barrier to prevent liquids, particles or gases from escaping or penetrating the application.

Viton seal is a generic term for products often taking the form of cut gaskets, strips, washers, extruded profiles and cord, all manufactured using the same material. Many of our Viton sponge seals can be supplied with a choice of self-adhesives which assists with the placement of the seal and to hold it in position.

    Seals are designed to prevent leakages once compressed between irregular surfaces, having the incorrect shape, size or material would cause the gasket to fail, all of our seals are manufactured using specialised machinery,  as we understand the final cut and finish of the seal needs to be perfect.

    Why use Viton Sponge Seals?

    Viton sponge seals have a vast number of highly desirable resistance and mechanical properties, making them the number one choice for sealing, gaskets and insulating application in harsh environments.  There are many different forms and profiles of Viton sponge seals available as the majority are bespoke made. 

    As they are produced using the exact same material, they will still all possess the same mechanical properties making it a popular choice across many industries.  Not only is Viton sponge tear resistant due to its skin finish, but it also has a wide working temperature range of  -20°C to +210°C and is resistant to chemicals, fuel, ozone, weather, lubricants, animal/vegetable oils and hydrocarbons. 

    These properties mean this material can be used for high temperature sealing such as within engine bays and other automotive applications, but also in applications requiring acoustic and vibration dampening in construction and resistance to oils, acids and other chemicals.

    • Environmental resistance (ozone/weather)
    • High Chemical Resistance
    • Weather & hot water-resistant
    • High-Temperature Range

    The Advantages of Using Viton Sponge Seals

    There are many advantages to using Viton sponge seals as the material is a high performance, versatile and durable, with increased strength from the skins, providing tear and puncture resistance.  Being a closed cell sponge, even without the skins, the material will not allow the ingress of air or fluid into its cell structure.

    Viton sponge is available in a range of standard pre-manufactured thicknesses, which can be used to convert into a number of other products such as gaskets, strips, rolls, washers, etc.   Viton sponge seals can be easily cut, pressed or extruded into the desired profile without the risk of tearing or stretching the material.
