SCE Gaskets Exhaust Collector Gasket
SCE Gaskets Exhaust Collector Gaskets: Engineered to Seal, Built to Last
When exhaust gases escape at the collector — that critical junction where individual header tubes merge into a single exhaust pipe — the result is lost power, unwanted noise, and heat that can damage surrounding components. SCE Gaskets has been solving this problem since 1990, and their lineup of exhaust collector gaskets represents decades of refinement in copper metallurgy, material science, and real-world racing validation.
The Pro-Copper Advantage
SCE's Pro-Copper Embossed collector gaskets are the cornerstone of their exhaust sealing lineup. The original SCE Pro Copper exhaust gaskets feature an embossed O-ring around the exhaust port, increasing sealing pressure to deliver a tight, permanent, leak-proof seal even on irregular surfaces — and SCE invented and introduced the embossed copper exhaust gasket back in 1995. At 0.043" thick, the embossed copper construction concentrates clamping force exactly where it's needed most, conforming to minor surface irregularities on collector flanges without requiring machined-perfect mating surfaces.
For applications where a softer seal is preferred, annealed copper gaskets at 0.062" thick are softer than the Pro Series , making them ideal for collector flanges that have seen some wear or slight warping over time. Solid copper exhaust gaskets eliminate exhaust gasket leaks — they will not shrink, deteriorate, or blow-out — and are available for applications ranging from specialized racing engines to OEM replacement.
Graph-Form: When Surfaces Are Far From Perfect
Not every collector flange is flat. For pitted, warped, or heavily corroded surfaces, SCE offers their Graph-Form collector gaskets. Graph-Form gaskets are best suited for warped, pitted, or uneven manifolds or headers, constructed from 0.150" thick ultra-high-temperature graphite and aramid fiber material, with flexible graphite header and collector gaskets that compress up to 50%. That extreme compressibility allows Graph-Form gaskets to flow into surface voids and create a reliable seal where rigid copper simply cannot.
Accu-Seal Pro for High-Heat and Forced Induction
Turbocharged builds and high-output naturally aspirated engines generate collector temperatures that can challenge conventional gasket materials. SCE's Accu-Seal Pro line is best suited for racing, turbocharged, and high-temperature applications, using 0.062" thick aramid fiber and graphite with a perforated steel core that provides stability and maximum torque retention, while also conforming to header sealing beads and cylinder head surface imperfections.
Sport Compact and Import Coverage
SCE also offers a Pro Copper collector/downpipe gasket that fits most sport compact manifold-to-pipe and header/collector connections, with a solid copper import down-pipe collector flange gasket covering most sport compact applications. This broad fitment makes SCE a go-to brand whether you're building a domestic V8 race engine or tuning a turbocharged import platform.
Why SCE Stands Apart
SCE Gaskets is a recognized leader in the manufacture of engine gaskets for automotive racing and high-performance applications, having developed many gasket innovations through advanced engineering, CNC technology, and dynamometer and on-track testing — including embossed copper exhaust gaskets and proprietary gasket coatings. Since 2018, the brand has been part of the Athena Group, which has allowed SCE to integrate cutting-edge technologies and further expand its product range, offering dedicated solutions for powersports, Harley-Davidson, OE engines, and the high-performance aftermarket.
Whether you're chasing tenths on the drag strip, sealing a turbo downpipe on a road course car, or simply replacing a leaking collector gasket on a weekend driver, SCE Gaskets brings proven materials and purpose-built designs to every application.
