Neoprene Washers

ASG meticulously manufactures Neoprene rubber washers using top-quality materials and cutting-edge machinery. Every washer is customized to meet specific requirements based on dimensions, samples, or drawings, even accommodating small sample runs when necessary.

The choice of machinery, whether atoms, autos, traveling head, kiss cut pressing machines, or CNC (oscillating knife), is determined by the washer's size and quantity. This ensures efficient production and minimized lead times.

Neoprene rubber material is readily available in various standard thicknesses, starting at a mere 1mm. It can be laminated to other materials or provided with a self-adhesive backing before gaskets are cut to precision.

What is a Neoprene Washer?

Neoprene, also known as Polychloroprene, is among our stocked materials that we skillfully convert into various products, including washers. A neoprene washer, typically a flat ring, is meticulously cut from a sheet or roll of this material. These washers are essential for creating level surfaces, acting as spacers, seals, or placed between nuts and bolts to evenly distribute pressure when tightened.

Neoprene rubber washers are frequently preferred due to their exceptional durability and high tolerance to extreme weather conditions. They exhibit outstanding resistance to oil, chemicals, and ozone exposure.

Moreover, these neoprene washers can be manufactured in a range of hardness levels, typically between 40° and 70° shore. The shore hardness is measured using a shore durometer, indicating the material's resistance to indentation. A higher number on the scale signifies greater resistance, which indicates a harder material, whereas a lower number indicates less resistance and a softer material.

    Washers serve diverse purposes, functioning as gap fillers, dust, air, or water seals, cushions, and spacers. At ASG, we produce washers from a wide array of materials such as neoprene, silicone, solid rubber, sponge, plastics, polyethylene, PVC, polyester, cork, textiles, and more. Our advanced machinery, including specialist presses and CNC equipment, ensures precision and quality in washer production.

    Why use Neoprene Washers?

    Neoprene rubber washers are highly versatile components, suitable for a wide range of applications as seals or spacers. Their excellent resistance to chemicals, UV radiation, ozone, and moderate resistance to oils, including animal and vegetable oils, makes them a valuable material. With a broad working temperature range, typically from -20°C to +70°C (varies by grade), and strong properties with excellent abrasion resistance, neoprene rubber washers are favored for outdoor applications. They find use in the automotive industry for sealing various components like window and door seals, pumps, hydraulics, and flanges.

    Different Grades

    Advanced Seals & Gaskets collaborates with a variety of material suppliers and manufacturers, providing customers with a diverse range of choices for neoprene rubber washers. Our offerings encompass several grades and hardness levels, with notable options including:

    British Standard 2752 (BS2752): This high-performance neoprene rubber boasts a broader working temperature range from -30°C to +120°C, exceptional resistance to aging, weathering, acids, inorganic salts, oils, and ozone. It also offers improved strength and anti-abrasion properties compared to standard neoprene. Available in shore hardnesses of 40°, 50°, 60°, 70°, and 80°.

    Flame Retardant Neoprene: Designed for temperatures from -30°C to +100°C, this material meets the flammability standard UL94-V0 and adheres to ISO 340. It is also tested according to anti-static BS 490 requirements.

    FDA-Approved Neoprene: Ideal for the food processing and pharmaceutical industries, this white neoprene complies with EC and FDA regulations. With resistance to fats, greases, vegetable oils, higher tensile strength, and a wide working temperature range of -30°C to +130°C, it's a favored choice.

    These neoprene rubber washer options offer varying properties to cater to diverse industry needs.
