Cometic Nissan RB-20E/DE/DET 2.0L 79mm Bore .051in Thickness MLS Head Gasket / Skyline

Cometic Gasket is an American, family-owned manufacturer specializing in high-performance gaskets and engine-sealing solutions. Founded in 1989 by four partners, including founder and CEO Bob Gorman, Cometic began in a 1,500-square-foot facility producing approximately 900 part numbers for the powersports market. The company now operates from a 70,000-square-foot research, development and manufacturing facility in Concord, Ohio, offering more than 85,000 products for automotive, powersports, marine, diesel, industrial and original-equipment applications. Cometic products are manufactured in the United States using American-made materials. Its catalog includes cylinder-head gaskets, complete engine gasket kits, intake and exhaust gaskets, seals and other components for stock rebuilds and demanding motorsport applications.

For Nissan Skyline GT-R and R35 GT-R engine builds, Cometic offers sealing components for both the RB26DETT and VR38DETT. Available RB26 products include MLS head gaskets in several bore sizes and compressed thicknesses, top-end and bottom-end gasket kits, intake-manifold gaskets, exhaust-manifold gaskets and throttle-body gaskets. VR38 options include left- and right-side MLX cylinder-head gaskets with multiple bore and thickness choices for standard and enlarged-bore engines. Cometic’s multi-layer head gaskets use embossed stainless-steel layers and specialized coatings to distribute sealing load around the combustion chambers. Because bore size, compressed thickness and surface preparation can affect fitment and compression, each gasket should be selected around the engine’s exact machining and build specifications.

Cometic Gasket does not provide a conventional manufacturer’s warranty for the performance parts listed in its catalog. Cometic states that these products are sold without an express warranty or an implied warranty of merchantability or fitness for a particular purpose. There is therefore no published warranty period or guaranteed repair, replacement or reimbursement program.

Cometic also states that it is not responsible for engine damage, property damage, labor, lost revenue, replacement components or other incidental or consequential expenses resulting from the installation or use of its products. Installing an aftermarket Cometic component may also affect the vehicle or engine manufacturer’s warranty coverage.

Customers should inspect all Cometic products before installation. To report a possible incorrect, damaged or defective item, contact Elite GT-R Parts with:

• Your order number and Cometic part number
  
• A description of the issue
  
• Clear photographs of the product and packaging
  
• Relevant engine specifications and measurements
  

Do not install, modify or return the gasket before receiving instructions. Custom gaskets produced with customer-selected bore sizes or thicknesses are considered non-returnable under Cometic’s published terms. Final assistance or any available resolution is determined after the product and circumstances have been reviewed.
