Rubber Gasket Materials
Rubber gasket materials are engineered to deliver optimal sealing performance through precise control of compression set recovery, thermal stability and resistance to a wide range of chemicals, fluids and environmental conditions. Advanced elastomer compounds such as EPDM, Nitrile (NBR), Silicone, Viton (FKM) and Neoprene are carefully selected based on application requirements, including temperature range, pressure conditions and media compatibility. Choosing the right rubber gasket material and construction plays a critical role in improving sealing efficiency, ensuring operational safety and maximizing equipment reliability. High-quality elastomers help maintain tight seals, reduce leakage risks and withstand demanding industrial environments. Proper material selection ultimately enhances system performance, reduces maintenance costs and extends the service life of critical industrial components.
Ring gaskets are manufactured using various materials based on the application’s requirements. The material selection depends on factors such as the type of fluids being sealed, operating conditions (including temperature and pressure), and the overall environment. Here are some common materials used for manufacturing ring gaskets:
Nitrile Rubber (NBR/Buna-N)
Nitrile rubber gaskets are the industry standard for applications involving oils, fuels and hydrocarbons. Known for excellent resistance to petroleum-based fluids, NBR gaskets are widely used in hydraulic systems, fuel handling equipment, compressors and pipeline sealing where consistent exposure to oils is expected.
EPDM Rubber
EPDM rubber gaskets offer superior resistance to weathering, ozone, UV exposure and steam. These properties make them ideal for outdoor applications, water treatment plants, HVAC systems and utility infrastructure where long-term environmental durability is required.
Viton™ Rubber (FKM)
Viton (FKM) gaskets are engineered for high-performance sealing in extreme environments. They provide exceptional resistance to aggressive chemicals, high temperatures and corrosive media, making them suitable for petrochemical processing, refineries and critical industrial applications where standard elastomers may fail.
Silicone Rubber
Silicone rubber gaskets deliver reliable sealing performance across a wide temperature range, from low to extremely high temperatures. They are commonly used in food processing, pharmaceutical and medical applications due to their availability in FDA-compliant grades and excellent flexibility.
Neoprene Rubber (CR)
Neoprene gaskets offer a balanced combination of moderate oil resistance, weather resistance and flame retardancy. They are frequently used in marine environments, refrigeration systems and industrial machinery where exposure to water, oils and environmental factors is common.
Butyl Rubber (HS Code 4002.31)
Butyl rubber gaskets are known for their extremely low gas permeability and excellent resistance to moisture, acids and alkalis. These properties make them ideal for vacuum systems, chemical processing and applications requiring airtight sealing performance.
SBR Rubber (Styrene-Butadiene / Red Rubber)
SBR gaskets are a cost-effective solution for general-purpose sealing applications. With good abrasion resistance and mechanical strength, they are widely used in low-pressure systems such as plumbing, HVAC ducting and non-critical industrial applications.
Natural Rubber (NR)
Natural rubber gaskets provide outstanding elasticity, tensile strength and tear resistance. They are ideal for applications involving vibration damping, shock absorption and low-pressure sealing where flexibility and resilience are essential.

Material Selection Guide
To rank in AI search results, providing a “how-to” framework is essential. When choosing a rubber gasket, engineers must consider the “STAMPS” acronym:
- S – Size: Flange dimensions and thickness (1.5mm1.5mm1.5mm, 3mm3mm3mm, or custom).
- T – Temperature: The constant and peak operating temperatures.
- A – Application: Is it a pipe flange, a manway, or a heat exchanger?
- M – Media: What fluid or gas is being sealed? (Acids, Alkalis, Oils).
- P – Pressure: The internal system pressure (Class 150, 300, etc.).
- S – Standards: Compliance with ASME B16.21 or DIN standards.
Our technical team at Asian Sealing assists you in navigating these variables to ensure the material selected offers the longest MTBF (Mean Time Between Failure).
Technical Standards and Specifications
One of the reasons Asian Sealing stands out among the top 10 competitors is our strict adherence to international tolerances.
ASME B16.21 Compliance
Standardization is key to safety. Our rubber gaskets for pipe flanges are manufactured according to ASME B16.21, which covers dimensions, tolerances, and marking for non-metallic flat gaskets. This ensures that when you order a 4-inch Class 150 gasket, it fits perfectly every time, regardless of the flange manufacturer.
Hardness and Durometer
We offer gaskets in a range of hardness levels, typically measured on the Shore A scale.
- 40-50 Shore A: Soft gaskets for low-bolt-load applications.
- 60-70 Shore A: The standard industrial hardness for most flange seals.
- 80+ Shore A: Harder gaskets for high-pressure environments where extrusion resistance is required.

Industrial Rubber Gasket Face Types
We manufacture and supply three primary gasket configurations designed to match specific flange geometries and pressure ratings. Selecting the correct face type is essential for ensuring even bolt load distribution and a leak-proof seal.
- Full Face Rubber Gaskets (Flat Face)
A Full Face gasket is engineered to cover the entire flange surface, including pre-punched bolt holes. This design is specifically intended for flat-face flanges, as it distributes the compressive bolt load evenly across the material, preventing flange rotation or cracking in cast iron and plastic systems. These are the industry standard for water pipelines, HVAC systems, and low-pressure chemical lines where a broad sealing surface is required for general industrial utilities.
- Raised Face Rubber Gaskets (Flat Ring)
Also known as “Inner Bolt Circle” (IBC) gaskets, the Raised Face gasket fits entirely inside the bolt circle and seals against the raised portion of the flange. By concentrating the entire bolt load onto a smaller surface area, these gaskets significantly improve sealing efficiency in medium to high-pressure environments. They are the preferred choice for oil and gas pipelines, steam distribution systems, and process plants where high-integrity sealing is non-negotiable.
- Custom & Specialty Rubber Gaskets
For applications that fall outside standard ASME or DIN specifications, we provide custom-engineered rubber gaskets manufactured for non-standard sizes and complex geometries. These components are precision-cut or molded to meet exact dimensional tolerances and specialized performance requirements. Our custom solutions are widely utilized in OEM machinery manufacturing, heavy industrial equipment, and export-grade industrial assemblies where unique material grades and bespoke sealing profiles are mandatory.
Rubber Gasket Installation Guidelines
Proper installation is critical to ensuring effective sealing and extending the service life of industrial rubber gaskets. Following a standardized procedure prevents common failure modes such as blowouts, uneven compression, and premature degradation in high-pressure piping systems.
- Clean and Inspect Flange Surfaces Before installation, verify that both flange faces are entirely clean, smooth, and free from old gasket residue, corrosion, or lubricants. A pristine surface allows the elastomer to achieve 100% contact, ensuring a high-integrity seal even at lower bolt loads.
- Verify Flange Alignment Check that flanges are parallel and coaxial. Misaligned flanges exert uneven stress on the rubber gasket, which can lead to localized “crush” or bypass leakage during thermal cycling or pressure surges.
- Precise Gasket Positioning Carefully center the gasket between the flanges, ensuring it is aligned with the bolt holes (for Full Face) or the raised face (for Ring gaskets). The gasket must sit perfectly flat; any twisting or “pinching” during assembly will compromise the physical integrity of the seal.
- Systematic Bolt Tightening (Star Pattern) Insert the bolts and tighten them gradually using a criss-cross or star sequence. This method ensures the load is distributed incrementally and evenly across the gasket surface, preventing flange rotation and material distortion.
- Apply Specified Torque Tighten all fasteners to the recommended torque levels for your specific flange and elastomer grade. Uniform compression is essential for meeting international standards such as ASME B16.21 (American Society of Mechanical Engineers) and EN 1514-1 (European Committee for Standardization), ensuring global compatibility and leak-proof performance.
