O Rings are one of the more simpler and effective seals ever invented: a loop of elastomer, with an o-shaped cross-section. O-rings are commonly made from viton, silicone, nitrile, and neoprene; and are available in metric and standard sizes.
Inseal stocks a number of standard size neoprene O Rings. Special sizes can be made as per order specifications.
Neoprene O Rings are commonly used in electrical installations and weather sealing applications. They are particularly suitable for use with water, whether salt or fresh water - although from drinking (potable) water it is better to use EPDM.
Inseal stocks a range of standard size EPDM O rings. Specials can also be supplied to order.
These o rings are used in sealing and electrical insulation applications.
EPDM is used frequently to seal in brake systems, and for sealing hot water and steam. Ethylene propylene compounds have good resistance to mild acids, detergents, alkalis, silicone oils and greases, ketones, and alcohols.
They are not recommended for applications with petroleum oils, mineral oil, di-ester lubricants, or fuel exposure. Ethylene Propylene has gained wide seal industry acceptance for its excellent ozone and chemical resistance properties and is compatible with many polar fluids that adversely affect other elastomers. The ethylene-propylene o-ring is commonly referred to as an EPDM o-ring, or EP, EPT, EPR o-rings.
Inseal stocks a range of standard size silicone o rings. Specials can also be supplied to order.
They are an excellent material for static service at extreme (hot or cold) temperatures. Outstanding flex and fatigue life. Very good for ozone and UV radiation service as well as for resistance to fungal and biological attack.
Due to their chemical stability they are useful in the pharmaceutical and food processing industries.
Our wide assortment of industrial products includes non-asbestos gland packings that are proficiently utilized in various industries. These are fabricated from a blend of chryssotile asbestos fibre and other raw material which is mixed with heat resisting rubber compounds to ensure maximum stability against high pressure and temperatures.
Inseal stocks a range of standard size viton O rings. Specials can also be supplied to order.
The Viton O Ringsare used in the presence of aggressive chemicals, fuels, and explosive gases. They offer excellent resistance to petroleum products and solvents. Very good high-temperature performance. Fluorocarbon elastomer make up the most widely used seals in the semi conductor industry.
Viton O Rings should be considered for seal use in aircraft, automobile, scientific instruments and other mechanical devices requiring maximum resistance to elevated temperature and to many functional fluids.
