Polylok offers a wide variety of mandrels to fit our seals. Combining mandrels or cutting them to size allows you to accommodate wall thickness from 1½” - 9”. Note: Mandrels should be cut 1/8'' less than your wall thickness. Polylok's mandrels are made from a polypropylene composite, allowing them to maintain their shape even during the most demanding applications. Each time you cast a Polylok Seal into your tank, you can be assured you will get a watertight connection.
