Neoprene Washers – Durable Rubber Washers for Sealing and Spacing
At Advanced Seals & Gaskets Ltd (ASG), we manufacture and supply high-quality neoprene washers suitable for a wide range of industrial, automotive, and commercial applications. Our washers are precision-cut from top-grade neoprene (polychloroprene) rubber, ensuring consistent performance, durability, and resistance to environmental challenges.
Whether you require custom sizes, laminated washers, or self-adhesive backed solutions, ASG has the expertise and machinery to deliver products that meet your exact specifications.
What Are Neoprene Washers?
Neoprene washers are flat, circular components cut from sheets or rolls of neoprene rubber. They are commonly used as spacers, seals, or load distributors between nuts, bolts, or other fasteners, ensuring even pressure and protection of surfaces.
Neoprene is widely appreciated for its durability, flexibility, and resistance to environmental factors, including oils, moderate chemicals, ozone, and UV exposure. Washers can be manufactured in varying hardness levels (typically 40° to 70° Shore), allowing customers to choose the right balance between flexibility and load-bearing capacity.

Why Choose Neoprene Washers?
Neoprene washers are highly versatile and used in many industries due to their:
- Excellent resistance to ozone, weathering, and ageing
- Moderate resistance to oil, greases, and fats
- Wide temperature range (-20°C to +70°C standard, higher for specialized grades)
- Durable and abrasion-resistant properties
- Waterproof and dustproof performance
These qualities make neoprene washers ideal for automotive, construction, outdoor, and industrial applications, including window and door seals, hydraulic systems, pumps, and flanges.
Grades of Neoprene Washers
We offer a variety of neoprene grades to suit different applications:
- Standard Neoprene: Ideal for general sealing and spacing applications with excellent weather, ozone, and abrasion resistance.
- BS2752 Neoprene: High-performance neoprene with extended temperature range (-30°C to +120°C), resistance to ageing, chemicals, oils, and improved mechanical strength. Available in Shore hardnesses of 40°, 50°, 60°, 70°, and 80°.
- Flame Retardant Neoprene: UL94-V0 and ISO 340 compliant, temperature range -30°C to +100°C, anti-static tested to BS490 standards.
- FDA-Approved Neoprene: White neoprene suitable for food and pharmaceutical applications. Resistant to fats, greases, vegetable oils, and compliant with EC and FDA standards. Operates between -30°C and +130°C.
Each grade is engineered to meet specific operational requirements, ensuring reliable sealing, spacing, and protection in challenging environments.
