Wastegate Copper Gasket - 2-Bolt 1.5 ID

The Wastegate Copper Gasket - 2-Bolt 1.5 ID by SCE Gaskets is an essential sealing component for any turbocharged or supercharged engine build. This gasket creates a critical seal between the wastegate body and mounting flange, preventing boost leaks that would compromise turbo efficiency and engine performance. Whether you're building a street performance machine or preparing a track-focused engine, a quality wastegate gasket prevents expensive damage from uncontrolled boost pressure and exhaust gas bypass.

SCE Gaskets engineered this wastegate gasket from high-temperature copper material, selected specifically for its superior heat resistance and conformability under extreme exhaust temperatures. The 2-bolt configuration with a 1.5-inch inner diameter accommodates standard external wastegate designs common in aftermarket turbo kits. Copper's thermal conductivity prevents hot spots at the gasket interface while maintaining a reliable seal cycle after cycle, resisting the thermal cycling and pressure spikes that degrade inferior materials like paper or composite blends.

This gasket suits builders upgrading factory turbos, installing standalone external wastegates, or refreshing aging boost systems where original seals have fatigued. Installation is straightforward: position the gasket between the wastegate body and the exhaust manifold flange, then torque bolts evenly to manufacturer specifications—typically 18–25 foot-pounds for M8 fasteners. Mechanics and tuners routinely specify this gasket for its reliability and performance in high-stress environments.
