What does a throttle body gasket do?

This gasket creates a seal between the throttle body and the intake manifold. It's crucial for preventing vacuum leaks, which can affect engine performance and idle quality.

Why is the rubber bonded to a carrier?

Bonding the soft rubber to a carrier, like steel or plastic, adds rigidity to the gasket. This makes it easier to install and handle, and can also improve its reusability.

What engines does this gasket fit?

This gasket is designed for GM's Vortec 4800, 5300, and 6000 Gen-3 Small Block V8 engines found in many Chevrolet and GMC trucks and vans.

Product Details

This is the Cometic throttle body mounting gasket, part number C5169. It's designed to create a reliable seal between your throttle body and the intake manifold on a range of GM trucks and vans equipped with the Vortec 4800, 5300, or 6000 Gen-3 Small Block V8 engines. If you're replacing your throttle body or just want to ensure there are no vacuum leaks around it, a fresh gasket is a smart move.

Cometic uses a molded rubber material with a soft durometer, meaning it's pliable enough to conform to the sealing surfaces and block any air gaps. For added strength and to make it easier to handle and reuse if needed, this rubber is bonded to a carrier, which could be steel or plastic depending on the specific application. This construction helps maintain a solid seal over time, preventing unmetered air from entering your engine, which can cause rough idling or performance issues.
