Best service behind their product. When I saw it was offered through Spruce, I didnt mind paying a little extra to get it. I had a previous problem with Fuel Tank gasket thickness, to which they helped resolve beyond my expectations. thanks for carrying this line. Dont mind the little extra for this product choice.

Much better than the paper gasket, just dont over tighten and use .041 safety wire

A great fix for what has always been a weakness and potential oil seep on most Lycoming 4 cylinder engines. Nice and thick, allows you to gently tighten the oil dip stick tube yet if it moves even a little bit has enough sponginess to maintain the seal.

Excellent alternative to the paper gasket. No leaks.

Far better than paper gasket. For flight training aircraft (6 planes 2500 hours annually) this definitely helps reduce engine oil mess. If tightened to much, as previously mentioned, it can squeeze out some. But, still reduces the amount of leakage greatly. As a tip we use .041 safety wire to hold the dip stick housings in place. This eliminates the stretching of the .032 safety wire when trying to remove an over-tightening dip stick.

Unfortunately this gasket doesnt work. It is too thick and soft. When you tighten the tube, it squishes out of shape. It needs to be thinner.

Rather thick and soft. Very slight torque (finger tight) forces the gasket out from under the tube base.

Q&A

Q: Regarding the complaints that the gasket is too soft ... when installing the silicone gasket (RG-72059) all surfaces must be TOTALLY clean and oil free, otherwise yes, the gasket will squish out ... same as their rocker cover gaskets. A&P-IA
