Good crush ring in hard to find size.
Good quality crush rings. 12m ID with 16m od is a little hard to find and work perfectly on older Mercedes Benz fuel delivery systems. Available nowhere near me and Mercedes dealer wanted $9+ a piece for them!

Fits m8 softail
Had a hard time finding these locally as the Harley dealership was out of them. They are a perfect fit for m8 softails with dual disc breaks!

Nice bag of rings
These are crush rings. You replace them when you change your oil. They fit on my Dodge Grand Caravan and do what I expect them to. No complaints on them and I have enough now for what I would expect for the life of my vehicle.

Good washers
I needed a copper washer to seal a pressure plug so I thought I would give these a try. Excellent choice. These washers are well made out of good quality materials. Fit and finish are excellent. Perfect fit. Works well. Highly recommend. 5 stars.
