Avoid sharp sealing edges and specify generous radii.<\/li>\n<li>Cost is several times that of silicone. Use it only where the low-temperature plus fuel combination is genuinely required \u2014 otherwise FKM or VMQ will do the job for less.<\/li>\n<li>Bonding to metal needs a fluorosilicone-specific primer; standard silicone primers do not hold.<\/li>\n<\/ul>\n<div class=\"callout\">\n    <strong>Tooling, not just material.<\/strong> Every material above behaves differently in the tool \u2014 shrinkage, gate position, cooling and ejection all change.

FVMQ when the seal must stay flexible below -40 \u00b0C, which is where FKM stiffens and leaks.<\/p>\n<h3>Is FVMQ suitable for aviation use?<\/h3>\n<p>Yes, in grades meeting the relevant aerospace specifications.
