Gasket - materials
• The choice of rubber material depends on

– Fluids-chemical attack or not
– The combination of temperature and pressure

• Rubber materials change properties due to

– Time-the rubber relaxes
– Temperature-the rubber deteriorates
– Hardening by attack of oxidising agents(e.g., oxygen in air)
– Swelling or softening by absorption of chemicals in the fluids

• Common gasket types

– Nitrile – EPDM – FKM


• Nitrile (NBR)

• NBR (standard material) up to 110°C
• NBR-HT(hight temperature) up to 130°C

• NBR (FDA)-food grade for standard NBR

• NBR-HT(FDA)-food grade for high temperatures NBR

• NBR-LT-for low temperature inrefrigeration applications


•HNBR(hydrogenated) for duties where normal NBR swells and for higher temperatures up to 150°C, more expensive

–Resistant to :

Many hydrocarbons, fats, oils, greases, hydraulic fluids, sea water,chemicals.

–Attacked by :

Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated and nitro hydrocarbons



• Standard material up to 150 °C

• EPDM (FDA)-food grade for EPDM.

–Resistant to :

Water, Animal and vegetable oils, ozone, strong and oxidizing chemicals.

–Attacked by :

Mineral oils and solvents, aromatic hydrocarbons.


• FKM, Fluorocarbon rubber

– Often called VITON (DuPont trade name) , used for aggressive chemical compounds

–Resistant to :

High temperature steam,aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils.

–Attacked by :

Ketones, low molecular weight esters and nitro containing compounds.

– Two different qualities usually used

• FKM G(VITON G) High performance and temperature resistance,much expensive than VITON A
