Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.098". 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.

Works as expected — good 4K signal and fast Ethernet
This Amazon Basics USB-C hub works exactly as it should. The HDMI connection gives a clean 4K signal to my TV, and the wired Ethernet connection is stable. I’m getting around 900 Mbps through the cable, which is very good for my setup. Power delivery also works normally. Overall, a simple and reliable hub that does the job well.

Fairly effective.
While I didn't bother reading instructions, it functioned as I intuitively thought with some slight troubleshooting. For example, using the correct USB-C for power or data. Connections to support an external monitor needs power toggling occasionally. Patience paid off. Expected a subpar Chinese knock-off (with questionable safety standards). But works very well, but can get warm.

Lots of great uses for this.
This hub is essential for a Quest or other virtual reality headset if you want to stream HDMI video to it. It allows you to hook up the HDMI source AND a power supply to feed to the headset to prevent the battery from running down.
