GRACO 961635 – Air Operated Mastic Fluid Pressure Regulator, 5000 PSI

GRACO 961635 – Air Operated Mastic Fluid Pressure Regulator, 5000 PSI

3/4 NPT(F) Ported Regulator with Carbon Steel Body designed for precision fluid pressure regulation in demanding industrial applications. Delivers regulated pressure from 500 to 4500 PSI (34 to 310 bar; 3.4 to 31 MPa) with included fluid pressure gauge for accurate monitoring.

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.
