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).

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.

Answers to all your possible questions.
What is the primary function of an industrial rubber gasket?
A rubber gasket acts as a high-performance seal between two stationary surfaces, such as pipeline flanges, valves, and pump casings. When compressed under a bolt load, the elastomer fills the microscopic irregularities of the flange faces, creating a leak-tight barrier that prevents the escape of liquids, gases, steam, or process chemicals.
How do I choose the right rubber gasket material?
Choosing the right elastomer depends on three critical factors: operating temperature, system pressure, and chemical media. For example, Nitrile (NBR) is the standard for oil-based systems, EPDM is the preferred choice for water and steam, while Viton™ (FKM) is required for aggressive chemicals and extreme thermal conditions.
Which rubber gasket material is best for oil and fuel resistance?
Nitrile (NBR / Buna-N) is the most common material for petroleum-based fluids and hydraulic oils. However, for high-temperature fuel applications or exposure to aromatic hydrocarbons, Viton™ (FKM) is recommended due to its superior chemical stability and degradation resistance.
What are the typical temperature limits for rubber sealing components?
Temperature ranges are material-specific : Silicone & FKM: Best for high-heat environments (up to 230°C). EPDM: Excellent for steam and outdoor weathering (up to 150°C). NBR: Ideal for moderate temperature oil applications (up to 120°C). Neoprene: Reliable for mid-range industrial uses (up to 100°C).
Are rubber gaskets suitable for chemical processing systems?
Yes, provided the elastomer is chemically compatible with the process media. EPDM offers excellent resistance to polar solvents and diluted acids, while FKM is the industry benchmark for acids, alkalis, and solvents in petrochemical and pharmaceutical processing.
Can rubber gaskets handle high-pressure industrial systems?
While typically used in low-to-medium pressure ranges, high-pressure performance can be achieved by using Raised Face (IBC) configurations, higher Shore A hardness materials, and thinner profiles to reduce the risk of gasket blowout or "creep."
Which international standards do your gaskets comply with?
Our industrial gaskets are precision-manufactured to meet global piping specifications, including ASME B16.21 (for North American flanges), DIN, EN 1514-1 (for European standards), and BS specifications. This ensures 100% dimensional accuracy and global compatibility.
What thickness should a rubber gasket be?
Rubber gasket thickness depends on flange condition, pressure class, and surface finish. Standard thickness ranges from 1.5 mm to 6 mm, but custom thickness can be manufactured based on application requirements.
Can rubber gaskets be customized?
Yes. Rubber gaskets can be custom manufactured in specific dimensions, thicknesses, hardness levels, and material grades to match non-standard flange sizes, OEM machinery requirements, and specialized industrial applications.
