VMQ O-ring 11.8 × 1.8 mm (inner diameter 11.8 mm, cross-section 1.8 mm). Outer diameter 15.4 mm. Hardness 70 Sh A. Temperature range -60 °C to 200 °C. Standard ISO3601-11.8x1.8. Certifications: FDA, USP_CLASS_VI.
For a static seal of this size (outer diameter 15.4 mm), the ISO 3601-2 / Parker O-Ring Handbook ORD 5700 design guidance recommends a groove depth of about 1.4 mm and a groove width of about 2.34 mm for the 1.8 mm cross-section — roughly 22 % squeeze.

Material properties
Silicone rubber (VMQ) has an outstanding temperature range from -60 °C to +200 °C (short-term +230 °C) and excellent biocompatibility. It offers superb resistance to ozone, UV radiation, water, polar solvents, dilute acids and most foods. Available grades with FDA, USP Class VI, BfR, EC 1935/2004 and 3A certification for food and pharmaceutical industries. Its weak mechanical strength is compensated by static applications — not suitable for dynamic sealing functions with high friction loads.

Suitable for various industries
Silicone O-rings are used in the food industry (CIP/SIP systems, milking machines, packaging lines), medicine (inhalers, catheters, dialysis equipment), pharmaceuticals (fermenters, valves), cosmetics and high-temperature static sealing applications.
Application notes
Ideal for food industry, pharmaceuticals and static high-temperature seals. Avoid dynamic applications with mineral oils — weak mechanical strength. For heavy steam prefer peroxide-cured EPDM.
