Cometic Gasket Automotive C5248-027 Cylinder Head GasketHead Gasket Cylinder Head Gasket Cylinder Head Gasket; 0.027 in. Multi-Layer Steel; 4.165 in. Bore; w/Steam Holes; SPECIFICATIONS:
FEATURES:
Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.027". With Steam Holes. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements. Cometic is dedicated to customer satisfaction and provides quality products, delivered on time at a competitive price, designed for each customer's specific application. Cometic is an industry leader in manufacturing processes and committed to pairing the highest possible quality materials with knowledgeable personnel. Cometic is also dedicated to continually improving all areas of its operations through employee development and involvement, as well as continual and comprehensive reviews of customer feedback. To ensure superior performance across a wide variety of engine types and sizes, Cometic manufactures gaskets from a comprehensive range of materials. Whether the situation calls for the latest in advanced technology like the MLS (Multi-Layer Steel) Gasket, or a synthetic blend such as Aramid Fiber, Cometic finds a solution. Cometic stays on the forefront of gasket design technology by utilizing in-house dynamometers and engine assembly rooms to bring its distributors, retailers and ultimately the end-user, the most reliable gaskets available today. Cometic combines advanced materials with the most current manufacturing processes to provide custom-tailored solutions to meet the needs of each individual customer.

| GLOBAL SHIPPING PROGRAM
How does shipping work? Placing an order outside the US is easy! In fact, eBay handles the entire transaction for you once we have shipped the product to their warehouse in Kentucky. Once the order has shipped you will receive a tracking number from our warehouse to Kentucky and then another tracking number from Kentucky to you. Additional Charges and Fees Additional shipping, duties and taxes will be calculated by eBay during check out. |
Outside the US? Don't worry, PartsHawk is currently shipping to over 100 countries
Check the Shipping and Payments section above to see if this item can be shipped to you. |
 |
 |
| What if my order shows shipped but the package is not moving?
At times there is a delay in the carrier’s tracking for updates. Please allow up to 24 hours for your tracking to update. If you still do not see any movement, please contact our Customer Service Department and we will be happy to assist. |
What if I am not available when the carrier tries to deliver?
If there is no response when the package arrives, the driver may leave the package nearest to the street or make a second delivery attempt on the next business day. Please check your tracking info as it will let you know the next steps for delivery attempt. |
How can I get a copy of my receipt or invoice?
|
|
What if the tracking number is not working after 24 hours? Depending on the size of your item, it could be shipped with a truck carrier and will require you to be present at time of delivery. Please feel free to reach out to us and we will provide additional details. |
I have special delivery instructions (i.e. Leave by back door, leave with neighbor, place in the planter on the left of my garage, etc.) We recommend leaving a note for the carrier on the door nearest to the street as we do not have a way to communicate those requests for you. |
Why did my item ship from a different location?
Many parts are stocked in more than one warehouse location. As a result your order may ship from a location other than the location shown in the listing. In most cases the shipping location will be closer to delivery address as we always try to ship from the closest warehouse to minimize transit times. In some circumstances intraday sales and other inventory changes may result in your item being shipped from a location further from your delivery address. |
|
Do I have to be there to sign for my package? If your order is over $250 there is a possibility it was shipped with a signature required option. The easiest way to check is to locate the tracking number for your order and open on the carrier’s website. There is no additional cost to you for this service. |
Can I pickup my part/order from your warehouse? Sorry, we do not offer the pickup in warehouse option as our warehouses do not have public access |
How do I know if this part will fit my vehicle? Check the vehicle compatibility guide above or just reach out to us. Updated 10.19.2023 |
