3 Bolt 4″ Annealed Copper Exhaust Gasket

Replacement gaskets for Fatz Built 4″ exhaust systems. Don’t suffer the rust stain tracking down your 4″ stainless exhaust with use of alternate steel based gaskets. We failed to find a good quality cost effective  gasket on the market so we designed and sourced our own. Made in annealed copper for a reliable seal. Incorporating an O-ring profile increasing tension in the required area for a reliable seal. Compatibility is only guaranteed with Fatz Exhaust systems though gaskets will suit other 3 bolt 4″ flanges.
