Copper Exhaust Nut m8 x 1.25 with 12mm OD
Our copper exhaust nut is perfect for all air cooled VW and Porsche applications as well as many other exhaust applications. Copper is far superior to steel for exhaust bolts. Our 12mm outer diameter is OE correct and allows for additional wrench space near the exhaust tube. It’s split design locks the bolt in place without fear of loosening eliminating the need for a lock washer.
