ED Rubber Seals are rubber sealing products. Custom rubber products can be developed according to drawings, samples, or working conditions, with support for different materials, hardness, sizes, and structures. They are used for oil, water, dust, and leakage prevention and can be customized to fit equipment structures. The product can be customized by drawing, sample, or application requirements, including size, hardness, color, and compound formulation. Typical applications include automotive parts, machinery, hydraulic and pneumatic systems, pumps and valves, pipe connections, electrical equipment, and general industrial sealing.

FAQ
Q: Advantages of ED seals over ordinary O-rings?
A: Significantly higher pressure resistance, can withstand over 30 MPa, while ordinary O-rings need backup rings above 10 MPa.
Q: What are the main application scenarios?
A: Mostly used for high-pressure sealing of hydraulic joints, oil pipe joints and thread end faces.
Q: What material is the backup ring in ED seals?
A: Backup rings are usually PTFE or polyamide (PA), with good chemical resistance and low friction, paired with O-rings.
