GRACO 903958 Spring Operated Mastic Fluid Pressure Regulator
The mastic regulator is ideal for low to high viscosity sealants or adhesives
These regulators control downstream pressure for mastic or semi-solid material. Install a regulator ahead of each spray gun or extruder gun in a multiple outlet system. The regulator provides precise pressure control to each spray gun from a common header system. It also dampens flow surges when line valves are opened and during pump stroke changeover.
