🏭 Factory Manufacturing Strength Tengye is a professional rubber sealing manufacturer with mature compression molding production lines and in-house mold workshop. We supervise every production step strictly. Premium EPDM rubber compounds sourced from qualified suppliers are adopted, without inferior recycled material. Full-process quality inspection covers raw material incoming test to finished goods outgoing audit, maintaining stable batch quality for global buyers of EPDM O-Ring.
🧪 Raw Material & Material Selection Standard We carefully select high-quality EPDM (ethylene propylene diene monomer) compound for EPDM O-Ring. Each raw batch undergoes laboratory testing before entering production. No harmful additives are used, ensuring stable weather resistance, elasticity and dimensional accuracy of finished seals for outdoor and hot-water applications.
⚙️ Molding Production Process We adopt mature compression molding and vulcanization technology.
➤ Production flow: Raw compound mixing → Mold opening → Compression molding → Vulcanization curing → Flash trimming → Dimensional & hardness QC
The EPDM O-Ring forms smooth surface, uniform section and no air bubbles or burrs. Full production flow is traceable for both prototype trial orders and mass bulk production.
🌡️ Core Material Features & Temperature Range
This EPDM O-Ring operates reliably from -50℃ to +150℃.
✅ Main performance characteristics:
• Excellent ozone, weathering and UV resistance
• Great resistance to hot water, steam and brake fluid
• Good elasticity and low compression set performance
• Stable performance under outdoor and alternating temperature environments
📍 Application & Working Environment It is widely used in automotive cooling systems, solar water heaters, washing machines, outdoor electrical enclosures, pumps and steam pipelines. It performs steadily under water, steam, brake fluid, sunlight and temperature fluctuation. It provides reliable sealing where ozone, weathering and hot-water resistance are required, which is exactly where EPDM O-Ring is widely demanded.
✏️ Custom Service & One-stop Support Custom processing according to your drawings or physical samples is available, covering standard AS568, ISO3601, JIS B2401 and non-standard sizes. OEM and ODM orders are welcome. Our engineering team offers fast quotation and rapid sample delivery for performance testing.
