Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.051". US Spec Only. 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.This Part Fits:

Excellent USB-C hub for my MacBook Air M3
I’m very happy with the UGREEN Revodok Pro 9 in 1 USB-C Hub. The packaging is very well done and gives a great first impression right out of the box.
The hub itself feels solid, robust, and well built. I have been using it for about two weeks with my MacBook Air M3, and so far, I have not had any issues. It is truly plug and play: my computer detects all connected peripherals immediately, and everything works as expected.
I also tested the display on/off button, and it works correctly. My current setup is the hub connected to my MacBook Air M3 with a 22” LG monitor through HDMI, while I connect a second 29” LG widescreen monitor directly to the laptop using a Thunderbolt cable.
With the MacBook lid closed and both external monitors connected, I get:
* 2560 x 1080 on the 29” HDR WFHD monitor
* 1920 x 1080 on the 22” Full HD monitor
One important thing to keep in mind: if you want to use three screens at the same time — two external monitors plus the MacBook screen — this setup will not work because the MacBook Air M3 does not support that configuration in this way.
I still need to test the SD card reader and PD charging, but based on my experience so far, this hub has worked perfectly.
Overall, great build quality, easy setup, reliable performance, and a very practical accessory for my MacBook. I definitely recommend it.

Solid, stable USB-C hub that works well with both Mac and Windows machines
Great dock that works well with with Mac and Windows, and seems to be able to handle anything I can throw at it. I've had other UGREEN combo video+usb dongles that really bogged down when I used the video port, however this one did not even break a sweat when pushing out 1080p@60fps from my MacBook while handling multiple USB inputs and outputs, power delivery, and ethernet all at the same time. Definitely would consider this to be some of the best value for money around on the budget-conscious side of the USB-C hub/dock market.
