DLSEALS High Quality EPDM NBR Rubber O Ring Cord
Rubber O-ring cords is a commonly used name for extruded sections made of homogenous rubber. We offer rubber cords in versions with round and square profiles. The selection of the right profile of the sealing cord depends on the application. Rubber sealing cords are made by the extrusion and free vulcanization of rubber mixtures.

Peculiarity Of O Ring Cord:
1)NBR O Ring Cord: Good chemical resistance to mineral oils and greases,hydraulic oils H, HL, HLP, non-inflammable hydraulic pressure fluids HFA, HFB, HFC to approx. +50°C and water to max. +80°C.
2)VITON O Ring Cord:
Good chemical resistance to mineral oils and greases, synthetic oils and greases,engine, transmission and ATF oils to approx. +150°C, fuels, non-flammable hydraulic pressure fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons, water to max. +80°C, excellent resistance to weathering, ozone and ageing, very low gas permeability (and therefore excellent for vacuum application) and resistance to a wide range of chemicals.
3)EPDM O Ring Cord:
Good resistance to hot water and steam, detergents, caustic potash solutions, silicone oil and greases, many polar solvents, and many diluted acids and chemicals, along with a high level of ozone resistance. EPDM materials are totally unsuitable for use with all mineral oil products (lubricants, fuels).
4) Silicone O Ring Cord
Good resistance to water (up to 100 °C), aliphatic engine and transmission oils, animal and plant oils and fats.This material complies with Positive List 21 CFR 177.2600 FDA. VMQ is generally not resistant to fuels,
aromatic mineral oils, steam (short term up to 120 °C possible), silicone oils and greases, acids and alkaline compounds.
