What Are Gasket Sealants?

An aerospace-grade gasket sealant can serve two functions. One is to make a custom gasket fitting, which is sometimes necessary for uniquely contoured surfaces or when the OEM gaskets are no longer manufactured. The other is to give current engine gaskets added strength and fill microscopic gaps, so they remain tight, reducing friction and preventing gas or fluid leaks.

Most gasket sealant kits use silicone, which offers watertight flexibility with excellent chemical and temperature resistance. Some have additives that help the gasket stay in place or transfer heat.

Aircraft Gasket Making and Sealing

We have a large selection of aviation gasket sealers, including conductive gasket kits and room-temperature vulcanizing sealants. Anaerobic gasket makers can cure in airtight spaces, letting you seal metal connections without needing to wait before further assembly or repairs. There are brush-on gasket compounds, squeeze tubes, and caulk sealant cartridges. Many products and kits are available in multiple sizes with bulk discounts for large OEM and MRO needs.

Silmid assists OEMs and MROs by offering more than just distribution. Our value-added services include exporting, product repackaging, a large reference document library, and knowledgeable technical support. Contact us if you need assistance choosing a gasket sealant or want to request a special-order quote.
