Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.060". 4 Bolts in Valley. 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.

Affordable fiber supplement!
Size: 84 Count (Pack of 1)
For starters, Amazon is one of the few places that sells these fiber tablets, so I was pleased that they were affordable. I prefer the tablets over the powder because it’s just easier for me to use. Three tablets and you’re good to go for the day. The fiber supplement works well compared to others I have tried. It’s very gentle on your stomach. Worth it!

Works well
Size: 84 Count (Pack of 1)
After having gastric bypass surgery, I needed a fiber supplement that was gentle on the digestive system. These are perfect. No bloating at all and they keep thing regular and moving along.

CONVENIENT BUT MAY BE HARD FOR SOME TO SWALLOW
Size: 84 Count (Pack of 1)
I've tried lots of different types of fiber supplements. For convenience, this one is the best. A lot has been said about how large the pills are for swallowing, but I have bigger pills than these, and they go down fine. The issue is the shape of the pill. It's made not cylindrical, but with 4 faces with sharp corners. These make the pills tend to stick a bit on the way down. I would not recommend these pills for someone with swallowing difficulties. That being said, they do work.
