Kastalon Filler Rings provide the most economical method for adjusting the ID size of a coil to fit a mandrel.

The easy slip on installation is accomplished with no down time or mechanical intervention.

Filler Rings prevent hard metal mandrel contact with the coil protecting against metal losses due to marking damage.

For greater versatility and protection, consider Kastalon Filler Plates and Mandrel Sleeves.

Kastalon's proprietary polyurethane chemistry gives better memory, longer life, and tighter fit.
