Cometic C4599-052 MLX Cylinder Head Gasket for Nissan TB48DE - 100.5mm Bore

Cometic C4599-052 Multi-Layer Steel Head Gasket for Nissan TB48DE

The Cometic C4599-052 is a precision-engineered MLX (Multi-Layer Steel with Stopper Layer) cylinder head gasket designed specifically for the Nissan TB48DE 4.8L inline-6 engine found in Nissan Patrol Y61 and Safari models. This high-performance gasket features a .052-inch compressed thickness and 100.5mm bore diameter, providing superior sealing for stock and modified engines.

Advanced MLX Technology

Built with Cometic's advanced MLX construction, this gasket features five layers of premium stainless steel with an integrated stopper layer that creates an enhanced sealing ring around each combustion chamber. The stopper layer improves clamp loads without excessive bore distortion, making it ideal for highly tuned TB48 engines. The compressed operating thickness measures .040 inches when fully torqued.

Premium Materials and Coating

Each layer is constructed from high-grade stainless steel selected for its exceptional tensile strength, corrosion resistance, and ability to rebound under extreme conditions. The outer layers feature embossed surfaces coated with Viton, a fluoroelastomer rubber that maintains sealing integrity at temperatures up to 482°F (250°C). This proprietary coating creates a micro-seal against both the cylinder head and block surfaces, eliminating the need for additional sealants.

Key Features:

• Application: Nissan TB48DE 4.8L DOHC inline-6 engine (2001-2016 Patrol Y61)
• Bore Size: 100.5mm (optimized for stock 99.5mm bore with gasket crush allowance)
• Compressed Thickness: .052 inches (5-layer construction)
• Material: Multi-layer stainless steel with Viton coating
• Design: MLX technology with integrated stopper layer
• No Re-torquing Required: Maintains clamping force without retorquing procedures
• Universal Compatibility: Works with aluminum heads to cast iron blocks

Performance Benefits

This gasket is engineered to handle the thermal expansion differences between the TB48DE's aluminum cylinder head and cast iron block without failure. The multi-layer design allows the gasket to withstand shearing forces while the embossed layers compensate for surface imperfections. Perfect for applications ranging from stock rebuilds to turbocharged performance builds, this gasket provides reliable sealing under extreme cylinder pressures and temperatures.

Installation Notes

Cometic MLS gaskets require no additional sealants or adhesives. Ensure cylinder head and block surfaces are properly cleaned and meet manufacturer's flatness specifications. Follow Nissan's torque specifications and tightening sequence for proper installation. The gasket is designed for single use and should not be reused.
