Rubber Gaskets

Rubber Gasket

Rubber is perhaps the most common type of jointing.

If you application involves potable (drinking) water you will require EPDM. Please visit the EPDM Gasket Page, by following the link on the left.

If your application involves water you should consider using neoprene or EPDM. If you require a part with oil and fuel resistance, you should consider nitrile.

The properties of the gasket will depend upon the type of rubber from which it is manufactured.

Parts can be manufactured from the following rubbers: Natural, Neoprene, Nnitrile, EPDM,  Silicone, Viton, Ethylene propylene,  and Butyl .

Rubbers can be used in a variety of working conditions,  and are typically used for water, oils,  chemicals; and other low-pressure fluid applications.

Neoprene Rubber Gaskets

Neoprene rubber gaskets (otherwise known as polychloroprene) exhibit good chemical inertia, and are commonly used in electrical installations and weather sealing applications.

These joints are particularly suitable for use with water; be that salt or fresh water – although from drinking (potable) water it is better to use EPDM rubber.

Remember that as a general rule you should select the thinnest material possible for your application.

Nitrile Rubber Gaskets

Nitrile gasketsare particularly suited for use with fats, oils, fuels, and other liquids contaminated by these; they can also be used at a range of temperatures (-40c to +120c depending on grade).

Nitrile rubber is also known as Buna-N, Perbunan, or NBR rubber.

Remember that as a general rule you should select the thinnest material possible for your application.

Silicone Rubber Gaskets

Silicone rubber gaskets are known for their chemical inertia and as such are useful in extreme environments, and temperatures from -55°C to +300°C.

Due to their chemical stability they are also useful in the pharmaceutical and food processing industries.

Remember that as a general rule you should select the thinnest material possible for your application.

EPDM Rubber Gaskets

EPDM rubber gaskets are used in anti-vibration, sealing, and electrical insulation applications.

These parts are widely used in the water industry, are WRAS approved, and sutible for use with potable drinking water.

EPDM is short for ethylene propylene diene monomer rubber.

Remember that as a general rule you should select the thinnest material possible for your application.

Viton Rubber Gaskets

Viton rubber gaskets are used in the presence of aggressive chemicals, fuels, and explosive gases.

Remember that as a general rule you should select the thinnest material possible for your application.

Parts are available in a range of bore sizes and tables; and either full faced (with bolt holes) or inner bolt circle (IBC or ring type joints).
