- Polyacrylate Oil Seals – Are mostly used in automotive and transmission industries as they can withstand fuel, oil, ozone, sunlight, and weather when used. With cars being exposed these daily they are the perfect choice. They do however become increasingly less flexible the lower the temperature gets.

Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.

Silicone (VMQ) Oil Seals
A valve cover gasket set typically includes all the necessary gaskets and seals required for the valve cover assembly. This comprehensive set ensures that all critical sealing components are replaced simultaneously, preventing potential leaks and ensuring the proper functioning of the engine. The inclusion of high-quality rubber valve cover gaskets in the set provides a reliable and complete sealing solution for the valve cover assembly.
