Perfect replacement
This O ring was the easiest part to replace. The fit was perfect and resolved my issue.

Fits as expected.
Perfect fit for a 2005 Mini Cooper R50 (2001 to 2006). Rubber is flexible like the original.

Solves BMW E90/91/92/93 gas cap seal issues instantly!
Any BMW E90/91/92/93 gas cap OEM or equivalent can have vacuum seal issue and "check gas cap" error messages. This seal is made of a different black rubber material and seems to be a slightly thicker. Easy swap out in minutes. My new fuel cap from BMW dealer was not sealing properly (bought 2 of them from different dealers - same confirmed part number). The seal is complete now and error messages have stopped!

Works great as a replacement o-ring for OEM gas cap.
My gas cap was deteriorating and I purchased a new gas cap, unfortunately it kept throwing a check engine light. I purchased this to go on my OEM part and it has worked without any issues, no check engine light. If you need a new o-ring for your OEM gas cap this is a great replacement.

East to install
While it didn’t resolve the evap error code on my 2012 Mini Cooper I was happy with how well it fit and how easy it was to install. It was an inexpensive attempt to resolve the issue.

Decent OEM Equivalent replacement part
Straight replacement for OEM part. Installed with no problems. Seems to be good quality and we'll see how long it will last.

Check engine light went out!
Check engine light came on on my mini cooper. Scan showed a leak in the evap system. Check the gas cap and saw o-ring was cracked and dry. Ordered this one from Amazon and 2 days later it was here. Very simple and straight forward to change. Half a dozen starts later, no more check engine light. Great price to boot! Recommend p RT o duct and seller!

Solucionó mi problema
Después de comprar 2 tapones compatibles con mi carro, resultó que el carro seguía prendiendo la misma alerta. Este empaque me permitió acondicionar el tapón de fábrica y adiós alerta.

Try flipping the old one over first.
Perfect fit.
