This Cometic copper exhaust header collector gasket is a .043in copper ring sized for a 2.5in diameter and a 3.5in bolt circle. Designed for extreme cylinder pressures, it resists burn-through and push-out, maintains torque set and requires no sealants. Corrosion-resistant construction and compatibility across differing head and manifold materials make it a durable choice for header-to-collector sealing in exhaust systems.
