Fluorosilicone rubber FVMQ sealing parts

Fluorosilicone rubber FVMQ sealing parts operate across a -30°C to 105°C temperature range, delivering good oil resistance at a cost-effective price point for general electrical sealing applications.

Product Parameters

- Material properties: formulated from fluorosilicone rubber (FVMQ), an elastomer that combines the flexibility of silicone rubber with added oil resistance from its fluorine content.
- Temperature range: rated for reliable sealing performance across a -30°C to 105°C range, suitable for moderate cold and warm operating environments.
- Oil resistance: offers good resistance to oil exposure, an important property for sealing applications near oil-filled transformers or oil-lubricated equipment components.
- Cost efficiency: positioned as a cost-effective sealing option relative to more specialized elastomers, providing solid performance for applications that do not require extreme temperature or corrosion resistance.
- Sealing function: maintains an effective barrier against moisture and contaminant ingress at equipment joints throughout its rated operating range.
- Application context: well suited to general electrical equipment sealing where oil exposure is a consideration but extreme temperature or corrosion resistance is not the primary requirement.

For sealing applications near oil-filled equipment that call for good oil resistance without the premium cost of more specialized sealing materials, this FVMQ seal's -30°C to 105°C range offers a practical, cost-effective balance of performance and value for everyday electrical equipment sealing needs.

Oil resistance and temperature performance are verified during production testing to confirm each seal batch meets its specified -30°C to 105°C operating range. Custom seal dimensions and profiles can be produced to match specific equipment joint designs, giving customers a cost-effective sealing option for general electrical equipment applications near oil-filled components. Technical data sheets covering oil resistance test results and the full rated temperature range are available on request to support engineering evaluation before specifying this seal into a project. Packaging is designed to protect seal geometry during shipping and storage, preserving performance through to final installation.
