Graco 15A063 PE-UHMW Vee Packing

Graco 15A063 PE‑UHMW Vee Packing

The Graco 15A063 PE‑UHMW Vee Packing is an OEM-grade sealing solution specifically engineered for demanding fluid-handling environments. Made from ultra-high molecular weight polyethylene (PE‑UHMW), this vee-style packing set offers excellent wear resistance, low friction, and reliable sealing performance—especially in applications where longevity and durability are critical.

Key Features

• Premium PE‑UHMW construction for outstanding abrasion resistance
• Vee-shaped design promotes tight sealing under fluctuating pressure
• Low friction coefficient helps reduce wear on rods and packing itself
• High impact strength for long-term operation in cyclical systems
• OEM-quality finish and fit for precise compatibility

Typical Applications

• Fluid pumps handling abrasive or particulate-laden materials
• Pumps that require long-life seals in high-cycle service
• Industrial systems where contamination risk is high
• Maintenance and rebuilds of Graco pumps using robust, wear-resistant packings
• Environments with frequent rod or shaft movement and heavy duty operation

Installation & Maintenance Guidance

• Clean the stuffing box and all contact surfaces before installing new packing
• Inspect rods or shafts closely for any scoring, scratches, or damage
• Install the vee rings in the correct orientation and compress evenly
• Apply recommended torque values to prevent seal extrusion or misalignment
• After assembly, run the pump at low pressure to verify sealing and performance

When to Replace the Packing

• When you notice fluid leaking around the rod or shaft
• If the packing rings show visible wear, deformation, or glazing
• When pump output or pressure becomes unstable or drops
• As part of routine maintenance or pump rebuild cycles
• If switching to more abrasive or harsh fluid types that strain current seals
