Walker Exhaust Pipe Flange Gasket Overview

The Walker 31668 exhaust pipe flange gasket is designed for reliable sealing in high-temperature exhaust systems. Engineered for Chevrolet and GMC heavy-duty trucks and vans, this donut-style gasket ensures a secure fit and long-lasting performance.

  • Gasket Type: Donut
  • Inside Diameter: 2.375 inches
  • Outside Diameter: 3 inches
  • Thickness: 1.03 inches
  • Material: High temperature graphite with wire mesh core

Durable High-Temperature Graphite Construction

This exhaust pipe flange gasket features a high temperature graphite material combined with a wire mesh core, providing excellent heat resistance and durability. The donut shape gasket with a 2.375-inch inside diameter and 3-inch outside diameter fits precisely between exhaust pipe flanges, maintaining a tight seal under thermal expansion and vibration. The 1.03-inch thickness helps accommodate flange irregularities and prevents exhaust leaks in Chevrolet C2500, C3500, K2500, K3500, Express 3500, Savana 3500, and Suburban models.

Compatible Vehicles and Applications

Compatible with Chevrolet and GMC heavy-duty trucks and vans, the Walker 31668 gasket is suitable for models including C2500, C2500 Suburban, C3500, Express 3500, K2500, K2500 Suburban, K3500, and Savana 3500. This gasket is intended for use in exhaust pipe flange connections where a reliable seal is critical to prevent exhaust leaks and maintain system integrity.

  • Prevents exhaust leaks at pipe flange joints
  • Reduces noise caused by escaping exhaust gases
  • Maintains proper exhaust backpressure
  • Protects against corrosion and flange damage
  • Ensures compliance with emissions standards

Installation Notes and Tips

When installing the Walker 31668 exhaust pipe flange gasket, ensure the flange surfaces are clean and free of debris or old gasket material. Proper alignment of the gasket and flange is essential to avoid leaks. Tighten flange bolts evenly to manufacturer torque specifications to maintain a consistent seal. This gasket is designed for direct replacement and does not require modification.

Quality Assurance and Warranty

Walker exhaust gaskets are manufactured to meet industry standards for durability and performance. The 31668 gasket is constructed with high-quality materials to withstand the thermal and mechanical stresses of exhaust systems. While specific warranty details may vary, Walker products typically come with a limited warranty against defects in material and workmanship.
