Expert in Custom Rubber & Silicone/Plastic Tubing, Seals, and Profiles – Comprehensive Solutions for Sealing, Fluid Transfer, and Structural Applications.
A silicone O-ring for lab equipment is a precision-engineered sealing ring designed to provide leak-proof, chemical-resistant, and high-temperature-tolerant performance in laboratory instruments, medical devices, and analytical systems. Made from platinum-cured or food-grade silicone, it ensures safety and reliability in sensitive environments. Key Features & Benefits ✔ Chemically Inert – Resists acids, bases, solvents, and sterilants (e.g., autoclaving, ethanol). ✔ High-Temp Stability – Withstands -60°C to 230°C (-76°F to 446°F), ideal for autoclaves and hot plates. ✔ Non-Toxic & FDA-Compliant – Safe for pharmaceutical, food, and medical applications. ✔ Flexible & Durable – Maintains elasticity after repeated compression cycles. ✔ Transparent/Colored Options – Visual inspection for contamination. Material Grades Type Best For Platinum-Cured Ultra-pure applications (PCR, bioreactors) Peroxide-Cured General lab use (cost-effective) Fluorosilicone Aggressive solvents (e.g., acetone) Common Applications Glassware Joints – Seals flasks, condensers, and reactors. Pumps & Valves – Peristaltic pumps, HPLC systems. Medical Devices – Syringe pistons, IV connectors. Installation & Care Lubricate with silicone grease for glass joints. Replace if swollen, cracked, or permanently deformed. Avoid prolonged UV exposure to prevent hardening.
