Triangle Collector Gskt. C/D=3in 1/2. B/C 4in 7/1

The FEL-PRO Triangle Collector Gasket with 3.5-inch diameter and 3-bolt configuration is a precision sealing component engineered for automotive exhaust systems where collector-to-manifold joints demand reliable, long-term containment. Built to OEM specifications, this gasket serves technicians, mechanics, and fleet maintenance professionals who understand that a compromised exhaust seal leads to performance loss, emissions leakage, and potential engine damage. Whether you're rebuilding a classic engine or maintaining heavy-duty equipment, the Triangle Collector Gasket delivers the durability and precision fit that professional shops have relied on for decades.

This gasket features a steel core laminate construction with 0.078-inch thickness—a critical dimension that ensures proper compression and permanent sealing under thermal cycling and exhaust pressure. The three-bolt mounting pattern secures the collector to the cylinder head flange with zero drift, eliminating micro-leaks that plague inferior materials. FEL-PRO's laminate design resists blowout and maintains integrity across temperature swings from cold start to sustained highway operation, where exhaust gas temperatures regularly exceed 1,200°F. The pair format (two gaskets per package) covers a complete rebuild or dual-collector application, reducing downtime on production schedules.

Installation is straightforward: position the gasket on the collector flange, align the three bolt holes, and torque fasteners in a star pattern to manufacturer spec—no specialty tools required. This gasket is compatible with any engine platform using a 3.5-inch, 3-bolt collector interface, making it ideal for engine swaps, restorations, and OEM maintenance. Professional technicians specify FEL-PRO for its consistent performance and minimal comebacks. Stock this part in your shop for rapid turnaround on exhaust system jobs.
