Precision Butyl Rubber Washers Manufactured in the UK
Bluemay Weston manufactures precision Butyl rubber washers to standard and bespoke specifications for customers across a wide range of industries. Produced using our punching and water jet cutting capabilities, Butyl washers can be supplied in small development quantities through to high-volume production runs.
Butyl rubber, also known as IIR or Isobutylene Isoprene Rubber, is a synthetic elastomer valued for its very low gas permeability, good weathering resistance and excellent resistance to water and moisture. These properties make Butyl rubber washers a practical choice for sealing, construction, HVAC, industrial equipment, electrical assemblies and other applications where dependable environmental resistance is required.
Excellent Resistance to Water, Weathering and Gas Permeation
Butyl rubber washers offer an effective combination of flexibility, environmental resistance and exceptionally low permeability to air and gases. This makes Butyl particularly useful for sealing applications where limiting the passage of air, moisture or gases is important.
The material also provides good resistance to ozone, weathering, water and many dilute acids and alkalis. Butyl is generally not recommended for prolonged contact with petroleum-based oils, fuels or hydrocarbon solvents, so alternative materials such as Nitrile or Viton may be more appropriate for those applications.

Frequently Asked Questions About Butyl Rubber Washers
Butyl rubber washers are commonly used in applications requiring sealing, water resistance, low gas permeability, cushioning or vibration damping. Typical uses include construction products, HVAC equipment, electrical assemblies, industrial machinery and general engineering applications.
Butyl rubber, also known as IIR or Isobutylene Isoprene Rubber, is a synthetic elastomer known for its very low permeability to air and gases. It also offers good resistance to water, moisture, ozone and weathering.
Butyl rubber offers excellent resistance to water and moisture and is widely used in sealing applications where water ingress needs to be reduced. The effectiveness of the finished seal will also depend on the washer dimensions, thickness, compression and overall assembly design.
Butyl has exceptionally low permeability to air and many gases compared with many other elastomers. This makes Butyl washers particularly useful in applications where reducing gas or air transmission is an important requirement.
Butyl rubber washers can typically operate within a temperature range of approximately -40°C to +120°C, although actual performance will depend on the material grade, formulation and application conditions.
Yes. Butyl offers good resistance to ozone, weathering and moisture and can therefore be suitable for many outdoor applications. The exact performance will depend on the grade and the environmental conditions involved.
Butyl is generally not recommended for prolonged contact with petroleum-based oils, fuels or hydrocarbon solvents. Where oil or fuel resistance is important, Nitrile rubber washers or Viton rubber washers may be more suitable.
Yes. Bluemay Weston manufactures Butyl rubber washers in both standard and bespoke sizes. Components can be produced to customer drawings, dimensions or samples using punching and water jet cutting techniques.
Yes. Butyl rubber has useful damping characteristics and its flexibility can help cushion components and reduce the transmission of vibration within an assembly. This can make Butyl washers suitable for equipment, construction and general industrial applications.
Both Butyl and EPDM offer good resistance to weathering, ozone and water. Butyl is particularly notable for its very low gas permeability and damping properties, whilst EPDM rubber washers are widely selected for outdoor and water-based applications requiring excellent resistance to weathering and UV exposure.
Bluemay Weston can manufacture Butyl rubber washers in quantities ranging from prototypes and small development batches through to high-volume production runs of many thousands or millions of components, depending on customer requirements.
