Copper crush washer used to seal Banjo and other fittings from leaks. These crush washers deform when tightened and must be replaced any time they are removed. Failing to replace these washers will almost certainly result in a leak. 12mm ID and 15mm OD.
Sold per washer.
This part is manufactured by an aftermarket supplier of European auto parts, including many sealing components. While not carrying OEM status, this part follows the design of the original very closely and uses similar materials. An aftermarket part may even have the same TUV approval as its OEM counterpart. The brand may even be OEM to another manufacturer besides BMW. This aftermarket brand has a two year warranty - the same as Genuine BMW and OEM brands.
