Rubber Gasket

Product Features

1. NBR Gaskets
Acrylonitrile-butadiene rubber gaskets offer excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. Service temperature range from -20°C to +121°C, with hardness from Shore A 40 to 90. Suitable for automotive engines, fuel systems, and hydraulic equipment where oil resistance is the primary requirement.

2. FKM Gaskets
Fluorocarbon rubber gaskets deliver superior resistance to high temperatures (up to +200°C, special grades up to +250°C), strong oxidizers, acids, and aggressive chemicals. Low compression set characteristics ensure reliable sealing under extreme conditions. Ideal for petrochemical processing, aerospace, and high-temperature industrial applications.

3. EPDM Gaskets
Ethylene-propylene-diene rubber gaskets feature outstanding weather, ozone, UV, and steam resistance. Service temperature from -57°C to +176°C. Non-polar nature provides excellent resistance to polar fluids including water, steam, and brake fluids. Widely used in HVAC systems, water treatment, outdoor enclosures, and steam applications.

4. VMQ Gaskets
Silicone rubber gaskets maintain flexibility across an exceptional temperature range from -100°C to +300°C, with excellent ozone and weather resistance. Inert, odorless, and non-toxic, with FDA and USP Class VI compliant grades available. Suitable for food processing, pharmaceutical, medical device, and electronics industry applications.

5. CR Gaskets
Chloroprene rubber gaskets provide a balanced combination of oil resistance, weather resistance, and aging resistance. Good resistance to refrigerants and ammonia makes them suitable for refrigeration systems. Service temperature range from -20°C to +121°C.

6. Specialty Gaskets
Custom solutions tailored for demanding operating conditions, including high-temperature grades exceeding +300°C, low-temperature grades down to -150°C, and chemically resistant grades for aggressive media. Custom formulations available for specific fluid compatibility, FDA/USP compliance, or extreme environmental requirements. OEM custom designs accepted based on technical drawings or application specifications.

Advantages

1. Broad Material Selection
Covering NBR, FKM, EPDM, VMQ, CR, HNBR, and custom compounds, enabling one-stop matching of the optimal elastomer to any temperature, pressure, and chemical environment.

2. Reliable Long-Term Sealing
Excellent elastic recovery compensates for flange surface irregularities and thermal cycling. Low compression set values (ASTM D395, dependent on elastomer type and test temperature; NBR/EPDM typical ≤25% at 70°C, FKM/VMQ high-performance grades achieve ≤15%) ensure maintained sealing contact stress over extended service life.

3. Custom Manufacturing Capability
Die-cutting and water-jet cutting support any 2D geometry with tight tolerances (±0.005"). Flexible minimum order quantities. No tooling costs for cut gaskets.

4. Wide Temperature & Media Compatibility
Service temperature from -100°C to +300°C. Compounds available for resistance to oils, fuels, acids, alkalis, solvents, steam, water, refrigerants, and aggressive chemicals.

5. Regulatory Compliance
Specific material systems and formulations are available with FDA 21 CFR 177.2600 (food contact), USP Class VI (biocompatibility), NSF 61 (drinking water), and WRAS approvals. Please consult our engineering team for material selection guidance.
