  • Motor oil seals are typically made from rubber or a similar material that is able to withstand the high temperatures and pressures present in an engine. They are placed in specific locations around the engine to prevent oil from seeping out through gaps or openings. Without these seals, oil could leak out onto the engine parts, causing damage and potentially leading to a loss of lubrication for the engine.

  • Regular maintenance and inspection of the oil seal are essential to ensure its continued effectiveness. Any signs of wear or damage should be addressed promptly to prevent oil leaks and potential damage to the machinery or equipment.


  • Obtaining adequate adhesion of fluoroelastomer compounds to metal inserts is a major consideration in fabrication of shaft seals. Adhesive systems worked out for bisphenol-cured VDF/HFP/TFE elastomers often do not perform adequately for peroxide-curable fluoroelastomers and more base-resistant polymers that contain little or no VDF. The trend toward use of more resistant fluoroelastomers in shaft seals has necessitated considerable effort on compounding and adhesive system development to get adequate bonding of the new materials. Silane-type primers are often used to coat metal inserts; these contain residual active groups such as amine functions that interact with the fluoroelastomer compound to attain good adhesion, especially for VDF/HFP/TFE elastomers. Other adhesive systems, using epoxy compounds or tie-coats, may be necessary for difficult bonding situations.3

  • There are several types of metal-to-oil seals available on the market, each with its unique design and application. Some of the most common types include
