Product Details
How to Select the Right Rubber Gasket Material
Use the STAMPS framework to define your rubber gasket requirement before ordering. Our technical team applies this same methodology to every custom enquiry.
- S — Size: Flange NPS, pressure class, and gasket thickness. Standard ASME B16.21 dimensions apply for Class 150 through 1500 flanges.
- T — Temperature: Continuous operating temperature and any peak excursion temperature. The material’s upper limit should exceed your peak, not just your average.
- A — Application: Pipe flange, pump casing, valve bonnet, heat exchanger, or custom equipment. Face type — full face or raised face — is determined by flange specification.
- M — Media: The fluid or gas being sealed. Oil and fuels → NBR. Water and steam → EPDM. Chemicals and acids → Viton FKM. Vacuum → Butyl. Food contact → Silicone or EPDM (FDA grade).
- P — Pressure: Operating pressure class (ASME Class 150, 300, 600, 900, 1500) determines minimum hardness and thickness. Higher pressure → harder compound and thinner gasket.
- S — Standards: ASME B16.21 (US piping), EN 1514-1 (European), BS 4504 (British), or DIN compliance.
Contact our engineering team with your STAMPS parameters and we will recommend the correct material, hardness, and thickness and provide a quote within 24 hours.
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.

Types of Rubber Gasket By Construction Type
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 Gasket
A full face gasket covers the entire flange surface including bolt holes. It distributes the compressive bolt load evenly across the sealing face, making it the preferred choice for flat-face flanges in cast-iron and plastic piping systems. Widely used in water treatment, HVAC, and low-to-medium pressure fluid systems.
Raised Face Rubber Gasket (Ring / IBC Type)
Also called an Inner Bolt Circle (IBC) gasket, the raised face type sits inside the bolt circle and seals against the raised flange face. By concentrating the bolt load on a smaller surface area, it delivers superior sealing efficiency for medium-to-high-pressure applications in oil & gas pipelines, steam systems, and chemical process plants.
Custom-Engineered Rubber Gaskets
For applications outside standard ASME or DIN specifications, we manufacture rubber gaskets in non-standard sizes, complex geometries, and speciality elastomer grades. Precision die-cut and water jet cut to customer drawings. Used in OEM machinery, heavy industrial equipment, and export-grade assemblies.
Rubber Gasket Installation Guidelines
Correct installation is as important as correct material selection. Most field failures in rubber gaskets are installation errors, not material failures.
- Clean and inspect flange surfaces — Both flanges must be clean, smooth, and free from corrosion, old gasket residue, scoring, or lubricant contamination. Any surface imperfection creates a leak path that no gasket material can bridge reliably.
- Verify flange alignment — Flanges must be parallel and concentric before the gasket is inserted. Pulling misaligned flanges together with bolt load imposes uneven stress on the gasket, causing localised crush and bypass leakage.
- Select correct gasket size and type — Confirm the gasket dimensions against the flange specification — NPS, pressure class, and face type. A full face gasket on a raised face flange, or vice versa, will cause immediate sealing failure.
- Centre the gasket correctly — Position the gasket centrally between flange faces. For full face types, align bolt holes accurately. For raised face types, seat the gasket squarely on the raised face. Any eccentricity causes uneven compression.
- Tighten bolts in star/cross pattern — Insert bolts hand-tight first. Then tighten progressively in a diametrically opposite (star) pattern to distribute compression evenly across the gasket surface. Avoid sequential (circular) tightening.
- Apply specified torque — Tighten to the torque values specified for the flange class and bolt size per ASME B16.21 and EN 1514-1. Under-torquing causes leakage; over-torquing damages the gasket through excessive compression or extrusion.

Answers to all your possible questions.
What is the primary function of an industrial rubber gasket?
A rubber gasket creates a static, leak-proof seal between two mating flange or equipment surfaces. By deforming under bolt load to fill surface micro-irregularities, it prevents fluid or gas leakage while also absorbing vibration and compensating for minor flange face imperfections.
Which rubber gasket material is best for oil and fuel service?
Nitrile rubber (NBR) is the standard choice for oil, fuel, and petroleum-based fluid applications. It offers excellent resistance to aliphatic hydrocarbons, mineral oils, and hydraulic fluids across a temperature range of -40°C to 120°C.
What rubber gasket should I use for water and steam lines?
EPDM is the preferred material for potable water, hot water, and steam applications. It offers strong resistance to heat, water, and weather degradation, and is available in FDA-compliant grades for drinking water contact. For high-pressure steam service above 150°C, consult our engineering team for compound selection.
Can rubber gaskets handle aggressive chemical service?
Viton (FKM) rubber gaskets handle the widest range of aggressive chemicals including concentrated acids, fuels, chlorinated solvents, and many proprietary industrial chemicals. For chemicals outside the FKM compatibility range, PTFE-encapsulated rubber gaskets or specialist fluoroelastomers may be required.
What does Shore A hardness mean for rubber gaskets?
Shore A is the standard scale for measuring rubber hardness. A 40-50 Shore A gasket is soft, providing a good seal at lower bolt loads on irregular surfaces. 60-70 Shore A is the standard industrial range for most flange sealing applications. 80+ Shore A is specified for high-pressure service where resistance to extrusion under load is required.
What rubber gasket standards do you manufacture to?
We manufacture rubber gaskets to ASME B16.21 (non-metallic flat gaskets for pipe flanges), EN 1514-1 (European flange gaskets), BS 4504, and BS 2494. Gaskets are available in standard dimensional series for all common flange pressure classes from Class 150 to Class 1500.
What thickness rubber gasket should I specify?
Thinner gaskets (1.5 mm-3 mm) are typically used in high-pressure, well-finished flange applications where minimal compression is required. Thicker gaskets (4.5 mm-6 mm) are used where flange surfaces are less smooth or where the application requires higher sealing force distribution. ASME B16.21 provides recommended thickness by flange class.
Can you supply custom-size rubber gaskets?
Yes. We manufacture rubber gaskets to any customer-specified dimensions using precision die-cutting and water jet cutting. Custom material grades, hardness levels, and thickness combinations are available. Provide your drawing or STAMPS parameters and we will quote within 24 hours.
Do you supply FDA-grade rubber gaskets?
Yes. We manufacture FDA-compliant rubber gaskets in Silicone and EPDM for food processing, beverage equipment, pharmaceutical manufacturing, and cleanroom applications where incidental food or pharmaceutical contact is possible.
Which countries do you export rubber gaskets to?
We export rubber gaskets regularly to the UAE, Saudi Arabia, Qatar, Kuwait, the USA, and across Southeast Asia. Our distribution hub in the USA supports North American supply requirements. All export shipments include material test certificates, dimensional inspection reports, and full customs documentation.
