DESCRIPTION
Our 8-H backups are manufactured from high quality hytrel. This tough material is long wearing with very good abrasion resistance in both dynamic and static applications and improved extrusion resistance compared to standard urethane or nitrile backups.
The 8-H has high temperature capabilities up to 275F along with a broad range of fluid compatibility including water based fluids.
