What do you use for tank cap gaskets for the Univair fuel tank caps? The ones supplied by Univair are made from butyl rubber so turn soft from auto gas fumes. I have tried to make my own using nitril rubber from a motorcycle inner tube. This works well, except for the fact that it blocked the tank vent on the last flight (thankfully only 25 min flight time). The tank was sucked in slightly, but there was an audible hiss when I removed the cap .
Does anyone have a good lead to cap gaskets made of silicone or nitril rubber?
