## Customer Reviews

### ⭐⭐⭐⭐⭐ Doesn't stink
*by D***E on June 24, 2025*

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.

### ⭐⭐⭐⭐⭐ Dimensional uniformity
*by T***S on July 6, 2025*

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

### ⭐⭐⭐⭐ Great for long lasting high quality hose or pipe gaskets
*by C***N on December 24, 2020*

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.
