Neoprene Gaskets & Rubber Gasket Material

Neoprene rubber gaskets are a top choice for engineers and procurement teams for good reason. Key performance characteristics of neoprene gasket material include:

Neoprene performs reliably across a temperature range of approximately -20°F to 250°F (-29°C to 121°C), making it suitable for outdoor, weather exposed environments, and moderate- temperature applications.

Neoprene offers good resistance to petroleum-based oils, hydraulic fluids, and many fuels, making it ideal for sealing applications in HVAC, mechanical, industrial and automotive environments.

Neoprene gaskets offer excellent resistance to UV, weather and ozone, and maintain performance and durability during outdoor exposure. Compared to natural rubber, neoprene provides superior long-term durability in outdoor environments.

Neoprene  exhibits good compression set resistance, allowing gaskets to retain their shape and sealing performance under sustained compressive loads.

Neoprene offers inherently flame-resistant material, and is well-suited for applications where fire safety is a consideration.

Neoprene provides good resistance to dilute acids, alkalis, and many industrial chemicals, while maintaining flexibility across a range of operating conditions.

At Excelsior, we work with multiple grades and forms of neoprene materials to meet a wide variety of sealing and component part requirements:

Dense and durable, solid neoprene gaskets perform in moderate compression sealing applications that can withstand high pressures and harsh environments. Solid neoprene gaskets are used in flanges, pipe systems, and mechanical assemblies requiring a consistent, leak-proof seal.

Closed-cell neoprene foam is lightweight and moisture-resistant, making it well suited for weather stripping, enclosure sealing, and vibration damping applications where a soft, compressible material is required.

Open-cell sponge neoprene provides excellent conformability, allowing it to fill irregular surface gaps and create an effective air and dust seal in low-pressure applications.

Using precision die-cutting and laser-cutting equipment, Excelsior produces custom neoprene gaskets in a wide range of shapes, sizes, or thickness to fit your exact design requirements. We work from customer-supplied drawings, CAD files, or physical samples to manufacture parts to your specifications.

Neoprene rubber gaskets are found in a wide range of industries and applications, including:

• HVAC & Refrigeration: Duct seals, compressor gaskets, vibration isolators
• Plumbing & Waterworks: Pipe flange gaskets, valve seals, faucet washers
• Automotive & Transportation: Engine gaskets, weather stripping, door and window seals
• Marine: Hull seals, hatch gaskets, pump seals in saltwater environments
• Electronics & Electrical Enclosures: Panel gaskets, EMI/RFI shielding seals
• Industrial Machinery: Pump gaskets, coupling seals, press platens
• Aerospace: Select sealing and cushioning applications where neoprene meets material and performance requirements

Neoprene gaskets are used to create a seal between two surfaces to prevent the leakage of liquids, gases, or air. They are commonly used in HVAC systems, plumbing, automotive assemblies, marine applications, electrical enclosures, and industrial machinery due to their excellent weathering, ozone and UV resistance, and ability to withstand exposure to water, oils and many industrial chemicals.

Neoprene rubber gaskets are typically rated for use between -20°F to 250°F (-29°C to 121°C). For applications requiring higher temperature resistance, materials such as silicone or EPDM may be more appropriate.

Compared to natural rubber, neoprene offers superior resistance to oils, ozone, UV exposure, and weathering. Neoprene is made of polychloroprene, a type of synthetic rubber which allows it to be more flame-resistant than other elastomers. Compared to EPDM, neoprene offers better oil resistance; compared to nitrile, neoprene provides better weather and ozone resistance. The right material depends on the specific requirements of your application.
