Rubber gaskets | Seals | O rings

J A Harrison stock a wide range of rubber gaskets, seals and o-rings

We stock rubber gaskets, seals and also o-rings, which are used for applications where pressures and temperatures are in an average range and chemical environments are mild. Most materials handle pressures up to 150 psi as well as temperatures from ‐60 ˚C up to 200 ˚C (dependent on grade). As a result, it is important to note that in the case of rubber and PVC gasket materials, the pressure and temperature ratings do not change much with significant changes in thickness. Furthermore, Silicone and Viton are two variants that can handle high temperatures of 200 ˚C.

Gaskets in stock

We stock material of various thicknesses. Therefore, it is easily converted to suit your requirements. In addition, three popular types of rubber materials, Ethylene propene (EPDM), Nitrile (NBR) and Neoprene (CR), all are resistant to common dilute acids and alkalis. Ethylene Propene (EPDM) has good mechanical properties and is resistant to ageing, weathering, ozone, oxygen, steam and also water. It is suitable for use with phosphate ester-based hydraulic fluids and many mineral acids, however it is not suitable for use with petroleum based oils or fluids.

Furthermore, we only hold WRAS approved EPDM which is suitable for use with potable water. Nitrile (NBR) is used in applications that have oil or petroleum residues. However, it is only to be used for temperatures up to 80 ˚C. Neoprene (CR) is a good general purpose material for rubber gaskets, recommended for use in less demanding situations with air, water, non-oxidising acid and also aliphatic hydrocarbons where extra resistance to heat, ozone or weathering is required.

Use fillers such as cloth to enhance basic rubber gaskets. Therefore, you give the product better recovery and more endurance. Rubbers with cloth inserts can handle movements and also higher compression. The cloth gives support during periods of extra stress and variable pressure. It can also be sensitive to excessive or prolonged pressure resulting in permanent deformation. Moreover, whichever grade you require, J A Harrison products provide the most productive results. Therefore our wide reach into the industry means you can find all your needs with us.
