Silicone Rubber Sheet,Heat Resistant, Heavy Duty,High Grade 60A,12 x 12 Inch, 1/25 Inch Thickness for DIY Gaskets, Pads, Seals, Crafts, Flooring,Cushioning of Anti-Vibration, Anti-Slip

Easily cut with gasket cutter. Seems to work fine and should be able to withstand weathering. Sheet will provide materials for many more gaskets.

Worked as need to cut custom rubber feet shapes.

This is a poor quality item . Describe as 12x12 I ordered 2 just in case and they are both odd shaped junk if you not going to make them square in shape with straight cut line side at least make them over sized so they can trimmed so they will be 12x12 . Straight JUNK !!!!!

I used this silicone sheet to repair a leaking drain pipe joint. I cut it to form a close-fitting sleeve around the joint connecting two pipe sections, and secured it with hose clamps. This high quality silicone is tough but compressible, so it can be used to seal surfaces that are not completely smooth--or even a curving surface depending on how clever you are in cutting the silicone. After clamping the sleeve there was no further leakage. This was a non-pressurized pipe; other methods might be more suitable for repairing pressurized pipes.

Although it worked OK for my project the adhesive is not very strong, it is tricky to get the rubber to stay in one place.

Worked great for my application. Used between a anchor plate and my kayak.

I purchased this rubber mat to cut four corners to hold up a plant, which I inserted pot into a pot. I noticed that even though the top pot was larger, it would still slip and turn. This rubber mat is perfect to keep my potted plant in place. Plus, it is heat and water resistant. The black mat camouflages nicely against my dark blue outer pot. I am pleased.

I like it. It is very excellent for my home made pressure can of tennis ball as gasket . It is a real rubber so that the sealing ability is powerful . I would like to recommend it.

Very flexible, good quality

This is perfect for what I needed - a (relatively) thin rubber sheet I could cut to size and use as gasket behind a doorbell intercom mounted on stucco. I searched high and low in a big box hardware store one night but came up empty handed. I found this at Amazon and couldn’t be happier.
