Graco 172487 Vee Packing

Product Description

The GRACO 172487 is a vee packing seal used in Graco spray and fluid-handling equipment. Vee packings are compression-style seals that prevent fluid from bypassing the piston or rod during pump operation. This component maintains internal pressure integrity and extends service intervals by forming a tight, self-energizing seal under system pressure. Installation is typically performed by a licensed spray equipment technician or experienced fluid-system mechanic during routine pump rebuilds or when leakage past the packing is observed during operation.

This vee packing is suited for use in Graco-brand spray guns, airless sprayers, and fluid pump assemblies where OEM-spec sealing performance is required. It is a replacement-grade component intended for use during scheduled maintenance or corrective service when the existing packing shows wear, extrusion, or fluid bypass. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid pump seal service. Before beginning work, relieve all system pressure, lock out the power source, and follow all applicable equipment safety procedures. Vee packings must be oriented correctly relative to the direction of system pressure — consult the equipment service manual for proper stack orientation and seating depth. Inspect the mating bore and rod surface for scoring before installing a new packing set.
