Product Overview

The Graco 15A068 PE‑UHMW Vee Packing is a high-precision piston seal specifically developed for Graco’s demanding industrial and displacement pumps. Constructed from PE‑UHMW (Ultra‑High Molecular Weight Polyethylene), this Vee-shaped packing combines wear-resistant properties with low friction, ensuring consistent piston performance and long-term durability.

This packing is ideal for high-cycle pumps, offering excellent resilience under pressure and smooth reciprocating motion, while significantly reducing leakage and maintaining system integrity.

• Made from ultra-durable PE‑UHMW for superior wear and chemical resistance
• Optimized V-profile ensures tight dynamic sealing under high pressure
• Precision OEM design for exact fit in Graco piston assemblies
• Minimizes internal friction, contributing to smoother pump operation
• Built to handle high stroke counts and extended service intervals

Technical Specifications

Installation & Maintenance

• Orient the rings correctly in the piston gland to ensure uniform compression.
• Pre-lubricate with a compatible grease to minimize initial friction.
• Torque the gland nut per Graco’s specification to avoid over-compression.
• Inspect periodically for wear, extrusion, or leakage signs.
• Keep spare packings on hand for preventative maintenance and minimize downtime.
