Triangle Header Gasket 2-1/2in Collector

The FEL-PRO Triangle Header Gasket 2-1/2in Collector (SKU FEL2014) is a precision-engineered exhaust manifold gasket designed for applications requiring a 2.5-inch diameter collector opening with three-bolt mounting. This steel core laminate gasket delivers the compression seal integrity demanded in high-temperature exhaust environments, where header gasket failure can result in exhaust leaks, performance loss, and uncontrolled emissions.

Manufactured to 0.086-inch thickness, this gasket employs a laminated steel core construction that resists blowout under sustained thermal cycling and combustion pressure. The three-bolt flange pattern ensures proper clamping force distribution across the sealing surface, maintaining a consistent seal even as engine components expand and contract through repeated heat cycles. At 0.08 lbs per pair, the gasket is engineered for weight efficiency without sacrificing structural integrity—a critical balance in performance applications where every tenth of a pound matters.

This gasket is specified for engine builders, restoration shops, and serious enthusiasts rebuilding or upgrading exhaust systems on platforms using 2.5-inch diameter header collectors. Whether addressing a failed OEM gasket or installing a high-flow header upgrade, this FEL-PRO product provides the repeatability and durability expected from a brand with decades of engine sealing expertise. The pair configuration ensures complete coverage for dual-runner or split-design headers.

FEL-PRO gaskets are engineered to meet original equipment specifications while maintaining compatibility with aftermarket and performance applications. Proper installation requires correct bolt torque sequencing and clean sealing surfaces to maximize the gasket's sealing lifespan across multiple heat cycles.
