Description

High Temperature Hydraulic O Ring Strip Metric Excellent Chemical Resistance ? Metric O-Ring Cord, can be used to make custom sizes. Can be & quot;cold bonded& quot; or & quot;heat spliced and vulcanized& quot; We stock the most popular & quot;Buna-70& quot; and & quot;Viton-70& quot; materials ? 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. ? Cord stock is excellent for your metric custom size o-ring needs. Available in standard cross sections from 1mm to 20mm Available in Buna -70 and Viton -70 Metric sizes are also available.
