Reduce the risk of sustaining heat damage to your aircraft by shopping the selection of firewall sealants available from SkyGeek. Our high-temperature aviation sealant is made to protect aircraft from flash heat up to 2,000 degrees Fahrenheit. These sealants can also withstand extreme temperatures from -65 degrees to 400 degrees Fahrenheit for prolonged periods of time. You can easily extend your aircraft's lifetime by protecting it from harmful vapors and air as well as shielding it from heat damage with our high-temperature sealants. This extra layer of protection can also protect your airplane from corrosion, stress and weathering.

Many of these firewall sealants come ready to mix in two-component formulas. When the two parts of the sealant are mixed together, they form a spreadable paste or liquid that can be applied to your aircraft with the use of a spatula or an extrusion gun. After you've applied the sealant, let it cure for the specified amount of time and allow it to create a durable coating on your aircraft. Many of our fire-resistant sealants maintain their flexibility and bond strength, even when exposed to extreme temperatures. They also form strong bonds with many metal substrates, including aluminum, steel and stainless steel. In order to ensure that our customers get great deals on high-quality sealants, we only offer products manufactured by trusted aerospace brands. Some of these manufacturers include Cytec, Flamemaster, PPG PRC-DeSoto and more.

SkyGeek combines an extensive selection of airplane parts and equipment with a friendly and knowledgeable customer service staff to create an outstanding shopping experience. We're proud to offer great deals to individual aircraft mechanics and owners as well as large aviation corporations. You can buy single units or place bulk orders of most of our products. Look to our stock any time you need to repair, maintain or construct an aircraft. You'll be sure to find all of the aerospace tools and equipment, shop and hangar supplies, engine parts, avionics and instruments that you need to get the job done.
