Reviews

These are definitely great quality and fits like a glove/tight. I had 1 really loose fuel cap on my PA 28-180 thought maybe it was the cap. I decided to try the gasket first and bammmm. I am super happy now!!

Not the same thickness as original and does not make needed seal. Continue to look for replacement gasket.
