Is EPDM resistant to brake fluid?
While NBR and FKM have similar chemical resistance, EPDM is completely different. It is incompatible with petroleum (oil and gasoline), but it is compatible with alcohols (ethanol, methanol, and nitromethane), water, coolants (both ethylene and propylene glycol), and glycol-based brake fluid.
Can you use HNBR O-rings for coolant?
HNBR O-rings have wide application in the auto and oil industries. In old air conditioning and refrigeration equipment Chloroprene (CR) and Fluoroelastomer (FKM) are popular material with coolant system of HCFC (or CFC) and mineral oil.
Is NBR compatible with brake fluid?
Nitrile O-rings, which have a temperature range between -54 and 149 degrees Celsius, are suitable for use with water, petroleum oils and some hydraulic fluids. Nitrile O-rings are not advisable for use with automotive brake fluid, ketones, phosphate ester hydraulic fluids, and nitro and halogenated hydrocarbons.
Is methanol corrosive to rubber?
But methanol can have problematic effects on rubber seals such as o-rings, causing rubber swell in methanol-producing equipment as well as in seals where methanol is used as an additive.
Is methanol safe for rubber?
Natural rubber has high tensile strength, abrasion resistance resilience, tear strength, and low hysteresis with the best long-range elasticity. Main applications are tires, vibration mounts, springs, and bearings. Natural rubber is considered compatible with methanol.
Is EPDM compatible with hydraulic oil?
EPR copolymer ethylene propylene and ethylene-propylenediene rubber (EPDM) terpolymer are particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base.
Is DOT 3 brake fluid corrosive to rubber?
All DOT 3, 4 and 5.1 brake fluids are compatible with each other and with all systems. All polyethylene glycol-based fluids will not harm healthy rubber parts. Also, the additive packages will not damage or distort any rubber parts.
Does alcohol degrade rubber?
Exposing rubber to rubbing alcohol infrequently can cause discoloration and deterioration, but prolonged use of isopropyl alcohol will wear down and eventually destroy it. Ensure the longevity of rubber by keeping it away from rubbing alcohol.
Is EPDM good for alcohol?
EPDM has very good compatibility with drinking water, anti-freeze, glycol hydraulic fluids, alcohol, hot water, steam, cleaning agents, organic and inorganic acids, dilute acids and alkalis, ketones, phosphate ester hydraulic fluids and automotive brake fluids.
