Detailed Product Description

The Walker 31601 exhaust pipe flange gasket features a composite construction combining fiber and metal laminate materials, reinforced with a metal fire ring to withstand high temperatures and resist exhaust gas erosion. Its 4-bolt design matches the flange configuration on compatible exhaust pipes, ensuring a tight and secure fit. The gasket thickness of 0.058 inches balances compression and durability, maintaining a consistent seal under thermal expansion and vibration. Precise bolt hole spacing of 2.625 inches and 2.125 inches center-to-center, along with 0.5-inch diameter bolt holes, aligns with factory specifications for the exhaust systems on Buick Cutlass Supreme, Chevrolet Lumina, Oldsmobile Regal, Pontiac Grand Prix, and Monte Carlo models.

Common Applications and Problem Solving

• Seals exhaust pipe flanges to prevent exhaust leaks
• Eliminates noise caused by escaping exhaust gases
• Prevents harmful fumes from entering the vehicle cabin
• Maintains proper exhaust backpressure for engine performance
• Resists degradation from heat and corrosion over time

Installation Notes and Tips

Ensure mating flange surfaces are clean and free of old gasket material before installation. Align the gasket carefully with bolt holes to avoid misalignment. Tighten bolts evenly in a crisscross pattern to achieve uniform compression and prevent leaks. Avoid over-tightening, which can damage the gasket or flange.
