Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.070". 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.

  • The embossed outer layers of the gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes
  • The center or shim layer is an uncoated stainless steel layer which can be varied to accommodate multiple thickness requirements
  • Requires less clamp load creating less bore distortion
  • Conforms load distribution across the sealing area
  • Embossed Outer Layers Coated w/Viton

Good Speakers with plenty of volume.
Size: 1 Pair, Color: Black
Got these speakers just so I could have sound, but the speakers turned out to be better then I expected. The sound good and they have plenty of volume. I adjusted everything to full volume and it was way too loud. The only knock on these speakers is their built in volume knob is on the speaker cable and hangs below my desk (no big deal for me I set the hardware volume to almost max then adjust with my software volumes. The USB power made setup easy and they are compatible with anything with a line out port. Good speaker at a great price.

Bang for your buck!
Size: 1 Pair, Color: Black
Bought these for my Dell computer because the built-in speakers were hard to hear. These made a big difference right away. Sound is much louder and clear for music, videos, and everyday use. They don’t have a lot of bass, but for the price I really can’t complain. Good speakers if you’re looking for a simple and affordable upgrade.

Best used with Laptop
Size: 1 Pair, Color: Black
These speakers are of better quality than they seem and will probably surprise most if used properly. When hooked up to a computer or laptop (via usb and aux), they work AMAZING. But when I tried to hook them up to my ps5, the quality went way down— the sound ceiling and especially base is almost non existent when plugged into a gaming system. I still use them for my ps5 but only because I live in an apartment—when I move, I’m upgrading. However, the quality for the price is so good that I bought another pair for my classroom. It’s more than enough sound to get the job done. Classic, Solid Amazon brand quality getting the job done.

Budget Friendly Stereo Speakers for Both New & Old Mac Users alike.
Size: 1 Pair, Color: Black, Size: 1 Pair, Color: Black
I purchased these for my Father’s MacBook Air and he absolutely loves everything about them. It’s Ease of Use, and it’s Functionality with macOS despite it not being advertised on here. As a Windows Migrant to Now Mac User from my personal experience they work flawlessly on a Mac. The audio is great for what it is, and it’s USB powered making it to where you can repurpose old USB Cell Phone chargers into, PC/Mac Speaker Power Adapters in order to power it up. Without sacrificing your USB ports on your machines. Only downsides are you can’t control the lights, and that the cables are a little weird and do take some getting used to. Yet either way I highly recommend purchasing these Stereo Speakers for MacBook users, iMac users, Mac Studio users and Mac Mini users alike, who are looking for an Audio Upgrade while being budget conscious and all without sacrificing your desk space simultaneously.
