Silicone O Rings are Silicone Rubber / VMQ rubber sealing products. Silicone rubber (VMQ) provides excellent flexibility, wide temperature resistance, weatherability, and electrical insulation for sealing applications with large temperature variations. They are designed for axial or radial sealing, easy installation, and use in static sealing and selected dynamic sealing 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: Are silicone O-rings oil-resistant?
A: Not resistant to mineral oils or fuels; only suitable for oil-free or slight oil contact, e.g., appliances, medical, food.
Q: What are the characteristics of silicone O-rings?
A: Non-toxic and environmentally friendly, high elasticity, high and low temperature resistance, aging resistance, soft hand feel and good sealing performance.
Q: Pressure resistance of silicone O-rings?
A: Typically low pressure (<3.5 bar); prone to extrusion at high pressure, not suitable for hydraulics.
