The GRACO 246687 is an air-operated pressure regulator designed to control downstream pressure for mastic or semi-solid materials. 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 gun or extruder gun from a common header system, and dampens flow surges during valve operation and pump stroke changeover.

Key Features:

• Air Operated Mastic Fluid Pressure Regulator
• 246687
• Zinc-Plated Carbon Steel, Brass, Stainless Steel, Buna-N, Urethane, Tungsten Carbide
• Minimum regulated pressure: 0.7 MPa (100 psi)
• Designed for use with mastic or semi-solid materials in multiple outlet systems
• MSD201EN, Loctite 567 Low Strength Thread Sealant, Safety Data Sheet (English)
• Precise pressure control for each spray gun or extruder gun
• Dampens flow surges during valve operation and pump stroke changeover
• Robust construction for reliability and durability
• Ease of maintenance with accessible components

Applications:
Used in systems requiring precise pressure regulation for mastic or semi-solid materials, such as spray or extruder gun setups in industrial lubrication, sealing, or coating applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety in your system.
• Install the regulator ahead of each spray gun or extruder gun in a multiple outlet system
• Follow torque specifications for assembly: 35–40 ft-lb (47–54 N·m) for main connections, use Loctite TL–242 or 601 on threads as specified
• Torque other connections as per manual (e.g., 15–25 ft-lb (20–34 N·m) for certain fittings)
• Refer to the manual for detailed installation and maintenance procedures
