DESCRIPTION

Our 8-U polyurethane back-up rings provide added extrusion resistance and increased pressure rating to u-cups and polypacks with only minimal increase in gland width.

To help make the selection and ordering of the correct part number for the 8-U profile easy and efficient, the part numbering system used is very similar to that of our hydraulic u-cups and polypacks.

We offer the 8-U back-up rings in either solid and split (-ST) styles
