Solid Rubber Seals

Solid Rubber Seal Supplier

As one of the UK’s largest non-metallic material converters, Advanced Seals & Gaskets Ltd have a vast network of manufacturers and suppliers enabling us to offer an array of seals, including those produced using various grades of solid rubber. We supply the highest quality solid rubber seals taking the forms of gaskets, washers, O-rings, mouldings and extrusions, which are all designed for the purpose of preventing leaks or the ingress of air, fluids and gas, insulation and protection. All our seals are made to order and are produced using 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 offer most seal types in high or low quantities.

What is a Solid Rubber Seal?

‘Seal’ is a generic term for products often taking the form of cut gaskets, strips, washers, extruded or moulded profiles and edge trims.  They are often used as a gap-filler between surfaces, acting as a separator or a barrier to prevent liquids, particles or gases from escaping or penetrating the application and in a number of vibration dampening, sealing and insulating applications. Solid rubber has most of the same properties as its sponge and foam versions, but without the cushion and bounce, offering a more durable and resistant material. Solid rubber seals are available in a range of types each with its own set of characteristics, properties and resistances to suit different exposures and environments.

Why use Solid Rubber Seals? 

Solid rubber seals are available in a range of material types, grades, thicknesses and hardnesses, each with its own desirable properties for use in different applications and industries. Using solid rubber seals creates a tight, leak-proof seal that will remain unaffected when under the impact.  Solid rubber seals, depending on the material type, can have qualities such as good resistance to chemicals, UV, ozone/weathering, oils, acids and salts. Different grades of solid rubber have various working temperature ranges and have abrasion and tear-resistant properties. Solid rubber seals are a popular choice for outdoor sealing applications and for sealing components within the automotive industry such as window/door seals, pumps, hydraulics and flanges.

Different Grades

Advanced Seals & Gaskets work with a multitude of material manufacturers and suppliers, giving our customers more choice when designing their solid rubber washer solution, our most popular materials being:

Neoprene (CR) is one of our most popular solid rubber materials, with various thicknesses held in stock. Neoprene is suitable for use where there is exposure to grease, oil, acids, ozone and even seawater.

EPDM (Ethylene Propylene Diene Monomer) is another very popular solid rubber used for seals, great for use in outdoor applications.  This material is resistant to water, UV, ozone, weather, abrasion, alkalines, ketones and diluted acids.  

Nitrile (NBR) rubber is a popular solid material for seals used within the automotive industry where there is contact with petroleum, oil and grease.  

SBR (Styrene-butadiene rubber) is a cost-effective, commercial-grade, general-purpose rubber with good abrasion resistance, tensile strength and low compression set. (not sure use with petrol and chemicals).

Silicone (SI) is an excellent electrical insulation material that can operate at high and low temperatures. Silicone rubber performs well when exposed to UV, weathering, ozone and moisture, and is available in a range of colours.

Viton rubber seals are manufactured for more demanding applications where there are harsh chemicals and high temperatures present.  Viton rubber offers resistance to fluids, oils, acids and petroleum-based liquids.

Benefits of Solid Rubber Seals

The type of solid rubber used to manufacture seals will depend on the industry, environment and application it is going to be used in and what it will be exposed to. Depending on the material used, some of the benefits offered by solid rubber include:

  1. Popular for internal, external, marine & automotive sealing  applications
  2. Can be used with high or low temperatures and with harsh chemicals
  3. Variety of grades, colours, hardnesses available
  4. Impermeable to water, dust, air and gases
  5. Resistance to oils, petroleum fluids, acids, ketones,  chemicals,  greases and fats.
  6. excellent resistance to ozone, weathering and ageing
