    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.

    Frequently asked questions about this O-ring

    What is the temperature range of a VMQ O-ring?
    This VMQ O-ring is rated for continuous service of roughly -60 to 200 °C. The material tolerates brief temperature peaks higher, but near the limits service life drops significantly. If you operate at the edge of the range, ask our technician about a more suitable compound.
    What media is VMQ resistant to?
    VMQ (silicone/PTFE type) is physiologically harmless and covers a wide temperature range, so it suits food and medical applications. Its resistance to oils and mechanical abrasion is lower than NBR's — for oils, consider FVMQ or FKM. For a specific medium, check compatibility in our chemical-resistance chart.
    What do the dimensions of this O-ring mean?
    The size 250 × 5 mm gives the inner diameter × cross section. The inner diameter must fit the groove or rod; the cross section sets the seal thickness. When replacing, do not confuse inner diameter with outer diameter. If you search by standard (AS568, ISO 3601, JIS), use our cross-reference finder.
    What does 80 Shore A hardness mean?
    A hardness of 80 Shore A expresses the stiffness of the rubber: a lower number (50–60) is softer and seals an uneven surface better, a higher one (80–90) better resists pressure and extrusion from the groove. For most common applications the optimum is around 70 Shore A. Under high pressure, choose a harder material and possibly a back-up ring.
