The AS3209 series of o-rings are fabricated with fluorocarbon rubber, often referred to as "Viton", which provides remarkable heat and fuel resistance, making these o-rings perfect for aviation fuel system applications.
This was my first time using it, and it worked great! I had plenty of work time, and just 24 hours later it was fully cured and ready to go. Excellent product with fast service. Pilots HQ is now my go-to source for epoxy—it’s the best because it’s strong and reliable.
