DESCRIPTION

Our 8-NY nylon 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-NY profile easy and efficient, the part numbering system used is very similar to that of our hydraulic u-cups and polypacks. 

The 8-NY back-up rings are split for easy installation on one-piece pistons or inside rod glands.
