Inexpensive, replaced with a new one.
I used this service to replace the Exhaust System on my ADV150.
Since Gasket is a consumable item, we replaced the Gasket in the base of the exhaust pipe at the time of Exhaust System replacement with this product.
When tightening the Flange nut, I can feel the firm crush when it is new, so I think it is easier to manage Torque, so I am glad I was not stingy and used a firm new one.
