MATNIKS Food Grade Silicone Rubber Sheet 12x12-inch by 1/8 White - Duro Shore A65 High Temperature Heavy Duty for Gaskets DIY Food Covers Lids Sealing Material Supports Microwave Oven Protection

Bought this to make our own gaskets for my Berkey. Their rubber gaskets smelled like tires, affecting our water. This works great and no odor.

The sheet thickness and uniformity is perfect. I used strips cut with a rotery cutter to make a hot water tank gasket.

If you need silicone gaskets this works and comes in at least two thicknesses. You can cut out gaskets with small sharp exacting knife. Otherwise it is really hard to find gaskets of the sizes you might need. Yeah it’s expensive as it is not sold in smaller sheets like 4-in x 4-in which would be great.

Comes in a full sheet so you can make the seal the shape you need.

I used this for making large gaskets for my Jacuzzi whirlpool bath jets. It was easy to mark on the side that has a thin sheet for peeling off. It was very easy to cut round gaskets with screw hole. It worked perfect. Love this product!

Exactly what I was needing. Will be ordering more in the future. If you buy the red lid 1.3 gallon carboys online for making mead and wine and lose the liner/gasket that is included under the lid this is literally the perfect material to replace it.

Tear very easily.

This Silicone Sheet, 1/8" thick, worked perfectly to make a new sealing gasket for my antique pressure cooker. The Presto Model 304 stainless steel copper bottom pressure cooker is the best pot ever made and the sealing gaskets are no longer available. The food grade silicone sheet was easy to cut and I was able to replace the old, dry, shrunken gasket to allow many more years of use - I hope!
