G-8627-Hd 1/8 Silicone Valve Cover Gasket

Great for stopping valve cover leaks...

Best gasket ever, doesn’t drip, lasts a long time. Got tired of replacing the cork gaskets

Easy to install and worked great. No more leaks

Nice quality. Easy install and a perfect fit.

The best valve cover gaskets made.

Great product!!!! As others have said works first time everytime. Definitely worth the money.

This is a great product! Ill never use a regular valve cover gasket again. It is important to follow the correct torque settings when installing them. It is easy to over-torque. It would have been nice if the package included installation instructions, but I had them elsewhere. Beyond that, I can just say they are great, and I cant imagine why every airplane doesnt use them.

These valve cover gaskets work first time and every time. No leaks. Great product !

the gaskets work great. I would like for aircraft spruce to update their website to include just the picture of the gasket being ordered. They have 6 or so gaskets pictured when you put your part# in and makes hard to determine if your getting the correct one. and the gasket that finally comes up with my part # is the wrong one! they did take the return and I finally got the correct one!!!!!

All four of these leaked through a lower bolt hole on my IO360 A3B6 engine. They look good and seem to be high quality but they simply didn’t work for me.

Was shocked to find that these gaskets all leaked along the bottom edge of the rocker covers on my IO-580. No torque setting worked, low, mid, high all leaked. Will go back to cork. These are an expensive disappointment.

Uncertified gasket that leaks like a sieve due to the oversized screw holes. Went back to cork after these were useless :(
