Parker Hannifin Silicone (VMQ) Elastomers
Parker Hannifin Silicone elastomer materials are designed for sealing applications requiring excellent flexibility across broad temperature ranges, strong environmental resistance, and reliable performance in static sealing systems. Silicone, also known as VMQ or Silicone Rubber, is commonly used in O-rings, gaskets, diaphragms, sanitary seals, electrical seals, custom molded rubber parts, and environmental sealing systems exposed to high and low temperatures, ozone, UV exposure, and weathering. These materials are widely specified in aerospace systems, medical devices, food processing equipment, electronics, environmental sealing applications, and industrial systems requiring stable performance across extreme temperature conditions.
Canyon Components supplies high quality equivalents to many Parker Silicone elastomer compounds used throughout industrial and sanitary sealing systems. Our team supports replacement O-rings, gaskets, diaphragms, and custom molded sealing components manufactured from VMQ compounds for high temperature, low temperature, and environmental sealing applications. We also provide engineering support for material selection, temperature capability analysis, and sealing system optimization.

Limitations of Parker Hannifin Silicone Materials
- Silicone compounds generally provide lower tear resistance and abrasion resistance compared to HNBR or FKM materials
- These materials may not perform well in aggressive dynamic applications involving severe wear or extrusion conditions
- Standard Silicone compounds have limited resistance to petroleum fuels, aromatic hydrocarbons, and certain solvents
- Superheated steam exposure may shorten service life depending on temperature and operating conditions
- Silicone materials typically have lower tensile strength compared to many industrial elastomers
- Certain low molecular weight silicone oils may cause swelling in VMQ compounds
