The GRACO 246642 is an air-operated mastic fluid pressure regulator designed to control downstream pressure for low to high viscosity sealants or adhesives. It is constructed from zinc-plated carbon steel, brass, stainless steel, Buna-N, urethane, and tungsten carbide components. This regulator is intended for use in multiple outlet systems, providing precise pressure control to each spray or extruder gun from a common header system, and dampening flow surges during valve operation and pump stroke changeover.

Key Features:

• Air Operated Mastic Fluid Pressure Regulator
• 246642
• Zinc-Plated Carbon Steel, Brass, Stainless Steel, Buna-N, Urethane, Tungsten Carbide
• Minimum regulated pressure: 0.7 MPa (100 psi)
• Low to high viscosity sealants or adhesives
• Precise pressure control for each outlet
• Dampens flow surges during valve operation and pump stroke changeover
• Suitable for multiple outlet systems
• Robust construction for reliability and durability

Applications:
Ideal for controlling downstream pressure in systems handling low to high viscosity sealants or adhesives, such as in industrial lubrication, sealing, and adhesive application processes.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within GRACO equipment.
• Install the regulator ahead of each spray gun or extruder gun in a multiple outlet system
• Follow torque specifications for assembly (e.g., 30–40 ft-lb for certain components, 75–80 in-lb for others, and alternating patterns as specified in the manual)
• Use recommended thread sealants such as Loctite 567 or TL-242 where specified
• Consult the equipment manual for detailed installation and maintenance procedures
