Graco | 903958 Spring Operated Mastic Fluid Pressure Regulator
Graco
Model: 903958
This mastic regulator is designed for use with low to high viscosity sealants or adhesives.
These regulators manage downstream pressure for mastic or semi-solid materials. For systems with multiple outlets, install one regulator before each spray gun or extruder gun. The regulator ensures precise pressure delivery to each spray gun from a shared header system. It also mitigates flow surges that occur when line valves are opened and during pump stroke changes.
