346 O-Ring Epdm 4-1/8ID x 4-1/2OD 70 Duro Round Black 346E70
346 O-Ring Epdm 4-1/8ID x 4-1/2OD 70 Duro Round Black
This high-quality 346 O-Ring Epdm is designed for demanding applications in the construction industry, particularly for hose systems. Made from ethylene propylene rubber (EPDM), it boasts exceptional resistance to ozone, sunlight, and weathering, as well as good flexibility at low temperatures and excellent chemical resistance. Its peroxide-cured formula ensures superior heat resistance and a lower compression set, making it ideal for long-term usage. With a temperature range of -55°C to 125°C, this O-Ring is perfect for applications in extreme environments, providing reliable performance and extending the lifespan of equipment and systems.
Top product features:
- Excellent resistance to ozone, sunlight, and weathering
- Very good flexibility at low temperatures
- Good electrical insulation property
Top product applications:
- Hose systems in the construction industry
- Low temperature applications, such as in cold climates or refrigeration systems
- High temperature applications, such as in engines or other heat-intensive systems
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)
