The GRACO 155865 is a high-pressure union swivel designed to connect fluid lines in GRACO equipment. It is constructed for durability and is intended for use in high-pressure fluid transfer applications, such as those found in industrial spray systems. The material is not explicitly specified, but similar GRACO swivel unions are typically made from robust metals to withstand high pressures.

Key Features:

• Swivel Union
• 1/2"F x 1/2"F (1/2" NPT (F) x 1/2" NPSM (F))
• 7250 PSI (500 bar)
• Used on pistol-grip mastic Flo-Gun complete model 224472, Evenflo Automatic Pressure Control, and compatible with GRACO high-pressure spray systems
• High-pressure rating for demanding industrial applications
• Swivel design allows for flexible hose routing and reduced stress on connections
• Compact size (approx. 1.75" length, 1.1" width, 1" height)
• Designed for reliability and ease of maintenance

Applications:
Used in high-pressure fluid transfer systems, particularly in industrial spray equipment such as GRACO airless sprayers and mastic guns.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and maintains warranty and safety standards.
• Ensure threads are clean and free of debris before installation
• Use appropriate thread sealant or tape as recommended by GRACO
• Tighten securely but avoid over-torquing to prevent damage
• Inspect regularly for leaks or wear and replace if necessary
• Regularly check for leaks and proper function
• Replace the swivel union if signs of wear or damage are present
• Follow GRACO’s recommended maintenance schedule for the equipment
