Use to hold over flow container in place. The rubber fitting reduces vibration and eliminates slipping on the tube.

From wire to elephant tusks, these p-clamps can clamp anything that fits inside. Heavily used throughout the rocket industry, they handle heat, moisture, and hundreds of pounds before breaking. MS21919 has perfected the clamp. (While the above is true, I used them to hang a curtain rod.)
