Commercial Rubber Washers
Here at Advanced Seals & Gaskets Ltd, we offer a number of solid rubber washers, one of which is solid commercial rubber or SBR. Using high-quality material and state of the art machinery, our in-house conversion facilities produce a range of commercial rubber washers, all made to order and produced by using samples or drawings as a template to ensure the final product perfectly fits the application - even offering a small sample batch if required for testing.
Depending on the size and quantity of washers required, our production team will select from our range of atoms, autos, travelling head, kiss cut presses or for very large or thick washers, we can programme our CNC (oscillating knife) to produce the washers in the most efficient way to keep quality high, whilst keeping costs competitive and lead times as low as possible.
What are Solid Commercial Rubber Washers?
Solid Commercial Rubber (SBR styrene-butadiene rubber) is an economy-grade material, black in colour which has a higher wear resistance compared to solid natural rubber and remains flexible even at low temperatures.
SBR rubber compounds are often mixed with other polymers such as neoprene (NR/SBR), EPDM and Nitrile (NBR/SBR) which are intended to improve or add additional properties. Solid commercial rubber is available in a range of hardnesses of 60, 65 and 70 shore A.
Commercial rubber washers are a flat ring (comprising of an outer diameter (OD), inner diameter (ID) and the thickness) cut from a sheet or roll of materials, which is placed between two surfaces creating a level surface, acting as a spacer or between a nut/bolt to spread the pressure when tightened or to create a better fit for fittings such as screws and bolts. They are also used within equipment and machinery between moving parts for abrasion resistance, vibration dampening, sealing and noise reduction.

Why use Solid Commercial Rubber Washers?
Commercial rubber is a popular choice for use when cutting washers as it is a low cost, general-purpose material with high tensile and impact strength, resistance to abrasion and flexibility even at low temperatures. Solid commercial rubber has a working temperature range of between 70℃ to -20℃ and has good resistance to water.
SBR rubber washers are not suitable for applications involving chemicals, ozone, very strong acids, grease, fat oils and hydrocarbons. These washers can often be found used in many general-purpose applications such as wear buffers, impact pads in production lines, automotive parts, gaskets and seals.
Benefits of Commercial Rubber
- Excellent resilience and tensile strength
- Excellent seal against air, water and diluted mixtures
- Temperature: -20°C up to +70°C.
- Abrasion resistance
- Excellent impact strength
- Readily available material and easy to convert
Grades of Commercial Rubber Available
Advanced Seals & Gaskets work with many material manufacturers which gives our customers more choice. Commercial rubber is not only available as an SBR grade, but also blended with other polymers to give a cheaper alternative, some of these blends include:
CR/SBR (neoprene) is manufactured using neoprene rubber and SBR compounds to create a material with properties of premium grade material at a reduced cost. This material is generally used for gap sealing and dust seals. Commercial grade neoprene offers resistance to oils, grease, dilute acids and alkalies and are hard-wearing enough to be used outdoors.
NBR/SBR (Nitrile) is manufactured using nitrile rubber and SBR compounds to create a material suitable for general purpose gasketing. This commercial-grade rubber offers resistance to fuels, petroleum, oils and many solvents making it suitable for use within a variety of industrial applications.
EPDM/SBR rubber is another hybrid made up of 2 different compounds. This particular grade of material offers good resistance to weathering and Ozone deterioration and provides properties such as high tensile strength and tear resistance. Commercial grade EPDM rubber is typically used for applications such as pipe seals, weather strips and dust seals.
