NO MORE LEAKY FISH TANK!
Perfect thickness (dust do wish they had a 1/312” option). Had to make a custom gasket for my Reef tanks that would constantly drip from one of the bulkhead seals, tri,,e s a pice of the suite (food grade silicon 1/16” yjickness). And for the first time in 3 years the drip is gone. Was so happy that it worked so well that I changed all of the bulkhead seals to this, cuts easy, shushes just enough to seal the pressure in the saltwater. I wish I would have found this years ago!

Happy customer.
Excellent product, exactly what I needed. I purchased this to prevent my tv stand from sliding around on the tv cabinet it was sitting on. (Problem solved!). I imagine this silicon mat has many uses for a myriad of issues.

Custom gaskets in white
Exactly what I was looking for to produce custom gaskets for new shower and fixtures. Wanted the gasket to match the white shower background and succeeds perfectly.

Good rubber sealing material
Good quality rubber sealing material. Very good for making custom or replacement of seals that you can’t find replacements.

Sealing Gasket for Antique Presto Pressure Cooker Model 304
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!

Doesn't stink
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.

Joint d'étanchéité
Le produit se découpe bien et il est possible de faire des trous dans le matériel avec un simple perforateur à papier de bureau.
