Dimensioning of O-rings
Read more
The dimensions of the O-rings are always given as the inner diameter of the O-ring (d1) x the thickness of the material (d0). ETHYLENE PROPYLENE RUBBER (EPDM) Chemically resistant. Used with phosphate ester-based non-combustible hydraulic fluids and glycol-based brake fluids. Suitable for use: - water and steam +130 ºC (EPDM 55915 +150 ºC) - glycol-based brake fluids +150 ºC - many organic and inorganic acids - detergents, soda and alkalis. - phosphate-based hydraulic fluids (HFD-R) - silicone grease and silicone oil - many polar solvents (alcohols, ketones, esters) - Skydrol 500 and 7000 - good resistance to ozone, weather and aging Not suitable for: - mineral oil-based products (oil, grease and fuels) N.B. When using brake fluids, EPDM material suitability for the particular brake fluid should be checked. Heat resistance: Maximum usage temperature with water and steam approx. +130 ºC, EPDM 55915 +150 ºC (momentarily less). In air: approx. +130 ºC. Cold resistance: -55 ºC |
