Neoprene Seals

Neoprene Seals – Durable and Versatile Sealing Solutions

At Advanced Seals & Gaskets Ltd (ASG), we manufacture high-quality neoprene seals in a wide range of forms, including washers, gaskets, strips, O-rings, cords, and bespoke extrusions. Designed to prevent the leakage or ingress of air, fluids, and gases, our custom neoprene seals provide reliable performance across multiple industries.

Neoprene is highly valued for its resistance to water, chemicals, oil, and environmental exposure, combined with excellent durability, flexibility, and strength, making it an ideal material for various applications, including automotive, aerospace, marine, construction, and agriculture.

What is a Neoprene Seal?

Neoprene, also known as polychloroprene, is a synthetic rubber that maintains its structure and flexibility across a wide range of temperatures.

Neoprene seals act as barriers, joining surfaces together to prevent liquids, solids, or gases from escaping or penetrating an application. They can be manufactured as:

  • Cut gaskets

  • Washers

  • Strips

  • Extruded profiles

  • Cord

Many neoprene seals are available with self-adhesive backing, ensuring easy placement and secure positioning.

    Why Choose Neoprene Seals?

    Neoprene seals are a popular choice across industries due to their:

    • Durability and strength – Withstands harsh environments and mechanical stress

    • Resistance to water, dust, and chemicals – Ideal for outdoor and industrial applications

    • Excellent ageing properties – Resilient to ozone, UV exposure, and oxidation without becoming brittle

    • Wide temperature tolerance – Suitable for both cold and warm working environments (-20°C to +70°C standard)

    • Flame retardancy and chemical inertness – For enhanced safety in demanding applications

    These properties make neoprene seals perfect for automotive components, window and door seals, hydraulic systems, flanges, and construction applications.

    Benefits of Neoprene Seals

    • Suitable for external and automotive sealing applications

    • Durable and long-lasting

    • Available in a variety of grades, profiles, and thicknesses

    • Impermeable to water and dust

    • Moderate resistance to oil, greases, and fats

    • Excellent resistance to ozone, weathering, and ageing

    Advantages of Using Neoprene Seals

    Neoprene rubber seals provide reliable performance where a strong, abrasion-resistant material is required. They are ideal for extreme weather conditions, water exposure, salts, oil, grease, UV, ozone, and gas applications.

    • Flexible thickness options – Simple cutting for standard seals; extrusions for complex profiles

    • High strength and tear resistance – Enables precise cutting and shaping to meet exact specifications.

    • Customisation available – Tailored seals in bespoke sizes, shapes, and grades

    Neoprene Seal Grades

    • BS2752 (British Standard 2752): High-performance neoprene with a temperature range of -30°C to +120°C, resistant to ageing, weathering, acids, inorganic salts, oils, and ozone. Available in shore hardness 40°–80°.

    • Flame Retardant Neoprene: Operates from -30°C to +100°C, meeting the UL94-V0 flammability standard and ISO 340, with anti-static compliance to BS 49e.

    • FDA-Approved Neoprene: White neoprene for food processing and pharmaceutical applications, resistant to fats, greases, and vegetable oils, with a temperature range of -30°C to +130°C.
