Black Heat Resistant Thin Silicone Grade Rubber Gasket Sheet 12 by 12 inch,1/25 Inch Thick

Seemed pretty good quality. I needed to make solid gaskets and seal up a two stroke Superjet motor. Had to perform a leak down test and needed to seal exhaust and intake manifold on ski so cut in little rectangles to do so. Sealed motor good enough to hold pressure and find out if base gasket I bought was holding as should. Did the job great.

Needed a thin silicone rubber sheet to cut non-marring "gaskets" to protect surfaces. Works well. Attached to surfaces with silicone. Time will tell if they stay attached.

Although I could not use the product for my project, it was just as it was described on the website.

5 stars, very sticky, worth the purchase

Excellent product as advertised

Used this to repair vacuum diaphragm in older vehicle where parts are not available. Perfect for this use.

Supposed to be silicone, but it's too stiff for that.

Did not take the heat
