Overview

• The HBY Rod Buffer Seal is the newest in sealing technology for high performance cylinders.
• The HBY is designed specifically to serve as the primary seal in a sealing system.
• Superior abrasion and wear resistance of DISOGRIN 9250 ensures longer operating life than other urethanes.
• Designed with a back-up ring, the HBY is engineered to withstand higher operating pressures (spikes up to 8,000 psi) and temperatures than other seals.
• The dynamic sealing lip is knife-cut for best sealing efficiency.
• Low compression set of DISOGRIN 9250 means cycle after tough cycle, the HBY will continue to seal against leakage.
• No adhesion effect on sliding surface, even after long standstill.
• The patented static lip design, relieves any pressure build-up which may occur between the HBY
• and the secondary seal (e.g. the D-300).
• The HBY is the most reliable protection of your sealing system for maximum service life.
• Available in a number of standard sizes, inch and metric, up to 10” (250mm) diameter.
