Precision Nitrile Rubber Washers Manufactured in the UK
Bluemay Weston manufactures precision Nitrile rubber washers to standard and bespoke specifications for customers across a wide range of industries. Produced using our punching and water jet cutting capabilities, Nitrile washers can be supplied in small development quantities through to high-volume production runs.
Nitrile, also known as NBR or Nitrile Butadiene Rubber, is a durable synthetic rubber particularly valued for its resistance to oils, greases and many fuels. These properties make Nitrile rubber washers a practical choice for automotive, mechanical, hydraulic, industrial, agricultural and general engineering applications.
Excellent Resistance to Oils, Greases and Fuels
Nitrile rubber washers offer an effective combination of flexibility, durability and resistance to petroleum-based oils and greases. This makes Nitrile particularly useful for applications where washers may come into contact with lubricants, hydraulic fluids or fuel-related environments.
The material also provides good abrasion resistance and mechanical durability, making it suitable for sealing, cushioning and spacing applications within machinery and equipment. Nitrile is less resistant to prolonged outdoor weathering, ozone and UV exposure than materials such as EPDM, so the operating environment should be considered when selecting the most suitable rubber grade.

Frequently Asked Questions About Nitrile Rubber Washers
Nitrile rubber washers are commonly used where resistance to oils, greases, fuels and industrial fluids is required. Typical applications include automotive components, hydraulic equipment, pumps, valves, machinery, agricultural equipment and general engineering assemblies.
Nitrile rubber, also known as NBR or Nitrile Butadiene Rubber, is a synthetic elastomer particularly valued for its resistance to petroleum-based oils, greases and many fuels. It is widely used for washers, seals, gaskets and other industrial components.
Yes. Oil resistance is one of the main advantages of Nitrile rubber. Nitrile washers are commonly specified for applications involving lubricating oils, greases and many petroleum-based fluids, although compatibility should always be checked for the specific fluid and operating conditions.
Nitrile offers good resistance to many fuels and is widely used in automotive and fuel-related applications. Performance varies according to the Nitrile grade and the particular fuel or chemical involved, so demanding applications should be reviewed before manufacture.
Nitrile rubber washers can typically operate within a temperature range of approximately -30°C to +100°C, although specialist grades may offer different temperature capabilities. The actual operating range will depend on the formulation, fluid exposure and application conditions.
Nitrile can be used outdoors in some applications, but it does not offer the same level of ozone, UV and long-term weather resistance as EPDM. Where prolonged outdoor exposure is a primary requirement, EPDM rubber washers may be more suitable.
Yes. Bluemay Weston manufactures Nitrile 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. Nitrile washers are widely used for sealing applications, particularly where oils, greases or fuel-related fluids may be present. The correct washer dimensions, thickness, material grade and compression should be selected for the individual application.
Nitrile washers are generally preferred where resistance to oils, greases and fuels is important. EPDM washers offer superior resistance to weathering, ozone, UV exposure and water. The correct material therefore depends mainly on the operating environment and substances involved.
Both Nitrile and Viton can provide resistance to oils and fuels. Viton rubber washers generally offer better performance at higher temperatures and in more aggressive chemical environments, whereas Nitrile is a versatile and cost-effective choice for many standard oil and fuel applications.
Bluemay Weston can manufacture Nitrile 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.
