What is the best rubber for a gasket?
EPDM to +140 °C for water, steam and weather, NBR to +120 °C for oil and fuel, FKM to +250 °C for chemicals and fuel: the medium decides, not a single best rubber. Margo moulds and die-cuts gaskets in eight compounds to ASME B16.21, EN 1514-1 and JIS B2404, with tolerance to ISO 3302-1.
02 · SPECIFICATION REFERENCE
Gasket Materials and Standards
Standards are named by number, not paraphrased. Select the compound by media and service temperature, then confirm the flange or enclosure standard your drawing calls out. Dimensional standards govern the gasket outline; ASTM D2000 and D1056 govern the compound itself.
| AEM (Vamac®) | ASTM D2000 | −40 °C to +175 °C | Engine and transmission cover joints, hot oil-side sealing |
|---|---|---|---|
| FKM (Viton®) | ASME B16.21 · ASTM D2000 | −20 °C to +250 °C continuous to +200 °C | Chemical, fuel and petrochemical flange joints |
| NBR (Nitrile) | ASME B16.21 · ASTM D2000 | −30 °C to +120 °C | Oil and fuel flange joints, pump and gearbox housings |
| EPDM | ASME B16.21 · EN 1514-1 · JIS B2404 | −40 °C to +140 °C | Water, steam, brake fluid and weather sealing |
| Silicone (VMQ) | ASTM D2000 | −60 °C to +220 °C | High-temperature enclosures, lighting, food-contact grades on request |
| Neoprene (CR) | ASME B16.21 · ASTM D2000 | −40 °C to +120 °C | HVAC, refrigerant lines, duty where flame retardancy is specified |
| SBR | ASTM D2000 | −30 °C to +100 °C | Water and mild-service static joints |
| Natural rubber (NR) | ASTM D2000 | −20 °C to +90 °C | Joints that also damp; abrasion-side covers |
| EPDM sponge / hard foam | ASTM D1056 | −40 °C to +140 °C | C-pillar garnish, trim, cabinet and enclosure sealing |
Showing 9 of 9 entries. Dimensional conformity to ISO 3302-1, class M1 to M4 for moulded gaskets and E1 to E3 for extruded and die-cut sections, as recorded on the drawing. Ranges are typical values for the compound family and are not a specification for a particular part — see our technical disclaimer. Non-catalogue sizes and profiles made to print.
03 · MATERIAL SELECTION
Which Gasket Material Do I Need?
Each compound has a distinct chemical compatibility profile and temperature ceiling. Name the medium, the operating temperature and the flange or joint class, and we will tell you which to specify.
- Temp. Range
- −40° to +140°C
- Hardness
- 40–90 Shore A
Ethylene propylene diene rubber, the default for water, steam, coolant and weather-exposed joints, with excellent ozone and UV resistance. The compound most gasket enquiries end up specifying. Not for petroleum oils.
- Temp. Range
- −30° to +120°C
- Hardness
- 40–90 Shore A
Nitrile butadiene rubber, the general-purpose industry standard. Outstanding resistance to petroleum oils and hydraulic fluids at moderate temperature, which makes it the usual choice for oil-side flange and housing joints.
- Temp. Range
- −20° to +250°C continuous to 200°C
- Hardness
- 60–90 Shore A
Fluorocarbon rubber, the first choice for aggressive chemical environments. Resists petroleum oils, fuels and many solvents at sustained high temperature, and holds a joint where NBR would harden.
- Temp. Range
- −60° to +220°C
- Hardness
- 30–80 Shore A
Vinyl methyl silicone, the widest service range of the eight. Specified for enclosure, lighting and oven-side gaskets. Food-contact and biocompatible grades on request. Poor abrasion resistance — not a wear part.
- Temp. Range
- −40° to +175°C continuous to 160°C
- Hardness
- 50–80 Shore A
Ethylene acrylic elastomer. Holds compression-set stability where oil, heat and ozone act together — the condition that ends most cover-joint gaskets.
- Temp. Range
- −40° to +120°C
- Hardness
- 40–90 Shore A
Polychloroprene. Balanced across weather, refrigerants and moderate oil exposure, and the family we reach for when flame retardancy is specified. Common on HVAC and refrigerant-line joints.
- Temp. Range
- −30° to +100°C
- Hardness
- 40–90 Shore A
Styrene butadiene rubber. Abrasion resistance at low cost, for static joints in water and mild service. Not for oil or fuel contact.
- Temp. Range
- −20° to +90°C
- Hardness
- 30–80 Shore A
Polyisoprene. The highest resilience of the eight, specified where a gasket also has to damp or take repeated closing loads. Not for oil, fuel or sustained heat.
- Temp. Range
- −40° to +140°C
- Hardness
- ASTM D1056 grade to drawing
Closed-cell expanded EPDM to ASTM D1056, classified by type, class and grade rather than Shore hardness — the grade sets the force needed for 25% compression deflection. Specified where a joint has to seal against a large gap or an uneven face, as on C-pillar garnish and cabinet doors.
