The GRACO 193722 is a piston packing component, typically constructed from durable materials such as leather or synthetic compounds, designed to provide a reliable seal within the piston assembly of GRACO spray foam and fluid handling equipment. Its primary function is to prevent leakage and maintain pressure integrity during operation.

Key Features:

• Piston Packing (Vee Type)
• Designed for use in GRACO piston assemblies; specific equipment compatibility should be verified with the manual or GRACO specialist
• Provides reliable sealing for pistons
• Helps maintain pressure integrity
• Supports equipment longevity and performance

Applications:
Used in GRACO spray foam systems and other fluid handling equipment where piston sealing is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and equipment longevity.
• Soak leather packings in SAE 30W oil for at least 1 hour before installation for best results.
• Grease piston packings and sleeve top edge prior to assembly.
• Carefully slide piston assembly into the sleeve to avoid damage.
• Replace o-rings and other seals as needed during maintenance.
