228 O-Ring Epdm 2-1/4ID x 2-1/2OD 70 Duro Round Black 228E70
228 O-Ring Epdm 2-1/4ID x 2-1/2OD 70 Duro Round Black
This 228 O-Ring is made from high-quality EPDM rubber, providing excellent resistance to ozone, sunlight, and weathering, as well as good flexibility at low temperatures and chemical resistance. Its peroxide-cured formula offers better heat resistance and a lower compression set, making it ideal for long-term usage in the construction industry, particularly in hose systems. With a temperature range of -55°C to 125°C, this O-Ring is suitable for a variety of applications, including water treatment, HVAC, and industrial equipment. Its durable design ensures reliable performance in harsh environments.
Top product features:

- Good flexibility at low temperatures
- Good electrical insulation property
Top product applications:
- Construction industry hose systems
- High-temperature applications
- Low-temperature applications
Ethylene propylene rubber (epdm) is a copolymer of ethylene and propylene. Furthermore it is a terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diolefin) to permit vulcanization with sulfur. Generally epdm possesses an excellent resistance to ozone sunlight and weathering and has very good flexibility at low temperature good chemical resistance (many dilute acids and alkalis as well as polar solvents) and good electrical insulation property.Ul style"margin-top0px;padding-top 5px; padding-bottom 5px;" cure system peroxide-cured standard epdms are usually sulfur-cured. Sulfur-cured compounds offer better flexible properties but are more prone to hardening and have an inferior compression set with high temperature peroxide-cured epdms have better heat resistance and a lower compression set. It complies with long-time usage especially for hose systems in the construction industry but is more expensive and more difficult for production than the sulfur-cured epdms temperature rangeul style"margin-top0px;padding-top 5px; padding-bottom 5px;" standard low temp -55°c (-67°f) standard high temp 125°c (257°f)
