Cometic C5770-030 MLS Cylinder Head Gasket 87mm Bore .030" RHS Jaguar AJ30/AJ35

The Cometic C5770-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Jaguar AJ30 and AJ35 V8 engines, as well as Ford applications using the same engine platform. This precision-manufactured gasket features an 87mm bore diameter with a compressed thickness of .030 inches and is designed for right-hand side (RHS) installation.

Advanced MLS Construction:

This gasket is comprised of three layers of embossed stainless steel, providing exceptional strength, superior rebound characteristics, and excellent corrosion resistance. The outer layers are coated on both sides with Viton, a fluoroelastomer rubber material that remains heat resistant up to 482°F (250°C). This advanced coating is designed to withstand harsh sealing environments, varying load conditions, and different surface finishes. The center shim layer consists of uncoated stainless steel, which can be varied to accommodate specific thickness requirements.

Key Features:

• Material: Multi-Layer Steel (3 layers)
• Compressed thickness: 0.030 inches
• Bore size: 87mm (round bore shape)
• Orientation: Right-hand side (RHS)
• Viton-coated outer layers for superior sealing
• No sealants required for installation
• Ideal for aluminum-to-aluminum and aluminum-to-cast iron block combinations
• Embossed design promotes even clamp load and reduces bore distortion
• No re-torquing necessary

Performance Benefits:

Cometic MLS head gaskets deliver maximum sealing performance for high-output engines while withstanding the shearing forces created when mating dissimilar materials. The multi-layer design provides increased structural integrity compared to traditional single-layer gaskets, while the embossed pattern ensures consistent compression across the entire sealing surface. This results in a reliable seal that maintains its integrity under extreme temperatures and pressures.

Note: This gasket is manufactured to order with typical production and delivery times of 2-4 weeks. UPC: 191070139896
