Tengye | Silicone O-Ring Seals Silicone O-rings are premium elastomeric seals engineered for applications requiring high-temperature resistance, chemical inertness and food-contact safety. Manufactured in our strong factory with premium raw materials, each silicone O-ring is precision molded for tight, durable sealing across medical, food, electronics and industrial systems.
We are a professional silicone & rubber sealing manufacturer focused on precision molded parts. All silicone O-rings are produced with high-purity silicone compounds, with no reliance on branded raw material suppliers. Strict incoming material inspection runs before every batch, ensuring consistent raw quality and stable, dependable performance throughout production.
Our silicone O-rings are manufactured via precision compression molding. The complete flow includes: compound mixing → preforming → mold loading → high-temperature vulcanization → deflashing → dimensional inspection → appearance sorting → packaging. Controlled temperature, pressure and curing time minimize flash, control roundness and cross-section tolerance, and deliver clean, smooth sealing surfaces for reliable operation.
✅ Excellent heat resistance and low-temperature flexibility
✅ Outstanding chemical resistance and electrical insulation
✅ Inert, non-toxic, low-odor — food-contact & medical grade options
✅ High compression recovery, low compression set
✅ Standard working temperature: -40°C to +220°C (peak up to +260°C short term)
✅ Good ozone and UV resistance for long service life
✅ Note: not recommended for strong acid/alkali and high-pressure dynamic steam sealing
Silicone O-rings are widely used in medical devices, food & beverage machinery, water purification, coffee machines, electronics & semiconductors, lighting, household appliances, pumps, valves and sanitary fluid systems. They perform reliably in high-heat, chemically active and hygiene-sensitive environments, offering an ideal balance of safety and durability where standard rubber fails.
