Exhaust Gasket Universal 2-1/2in Col. Flg 2-Bolt

The REMFLEX Exhaust Gasket Universal 2-1/2in Collector Flange 2-Bolt (Model 8026) is a high-temperature graphite collector gasket engineered for exhaust manifold-to-collector connections on engines requiring reliable thermal sealing. This gasket pairs with 2-1/2 inch diameter collector flanges using a 2-bolt fastening pattern, delivering consistent compression and leak-free performance across repeated thermal cycles.

Manufactured from graphite composite material at 0.125 inches thick, the gasket provides optimal crush force distribution while maintaining structural integrity under sustained high-temperature exposure typical of performance and heavy-duty exhaust systems. The 2-bolt configuration ensures straightforward installation without complex alignment requirements, and the material's self-sealing properties reduce the risk of exhaust leaks that can compromise both performance and emissions compliance. Compact dimensions (6.5 x 0.4 x 11.1 inches) facilitate installation in tight engine bay configurations.

This collector gasket is suited for enthusiasts rebuilding carbureted or fuel-injected V8 engines, classic muscle cars, street rods, and off-road vehicles where manifold-to-collector sealing is critical to system integrity. It addresses a common failure point where factory or aged gaskets lose their compression seal, allowing exhaust gases to escape at the collector junction and reducing scavenging efficiency. Replacement is straightforward and requires no specialized tools beyond basic socket and wrench sets.

REMFLEX gaskets are recognized in the performance exhaust market for materials engineered to withstand thermal shock and vibration without permanent deformation. The graphite composition resists warping over thousands of heat cycles, making this gasket suitable for both street and track applications where reliability under variable engine loads is non-negotiable.
