The GRACO 166623 is a PTFE (polytetrafluoroethylene) O-ring packing designed for use in GRACO equipment, specifically as a sealing component in flow meters and pumps. Its primary function is to provide a reliable, chemical-resistant seal in high-pressure and high-temperature environments.

Key Features:

• O-Ring Packing
• 166623
• PTFE (polytetrafluoroethylene)
• Designed for GRACO flow meters and pumps, such as the R2 E30 Flow Meter and SaniSpray HP 750 Pump
• Chemical resistance due to PTFE material
• Reliable sealing in high-pressure environments
• Durable construction for extended service life
• Ease of maintenance and replacement

Applications:
Used as a sealing component in GRACO flow meters and pumps, suitable for applications requiring chemical resistance and high-pressure sealing, such as in industrial lubrication, spray systems, and fluid handling equipment.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety in critical sealing applications.
• Ensure equipment is depressurized and fluids are drained before installation
• Inspect the O-ring and mating surfaces for damage or contamination
• Lubricate the O-ring with a compatible lubricant if recommended by the equipment manual
• Follow the manufacturer’s guidelines for installation torque and sequence
• Regularly inspect O-rings for wear, cracks, or deformation
• Replace O-rings at recommended intervals or if signs of leakage are observed
• Use only genuine GRACO replacement parts for critical sealing applications
