GRACO 903958 – Stainless Spring Operated Mastic Fluid Pressure Regulator, 3/4″ NPT

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.
