I need to find a supplier of flexible fabric "socks" that we use to connect our load-cell-mounted hoppers to the barrels we're filling. It's a simple item but my internet searches haven't yielded anything similar.

The sock is basically an 8" tube with flanges sown to each end. Each flange has an 11" bolt circle. The material is some kind of resin impregnated fabric. This is a room temperature, low pressure application. The sock just needs to be air tight and flexible.

If anyone knows of a supplier or a more accurate term to help refine my search, please respond! ■
