Comet P40 Pressure Regulator | Summary
The Comet GCP 20 Pressure Regulator (42001-00838) is the OEM replacement pressure regulator for new-style Comet P40 diaphragm pumps used in professional soft wash systems. Built in Italy by Comet, it provides adjustable pressure control for the P40's high-flow 11 GPM, 300 PSI operating range.
Designed as a direct replacement for the P40, the GCP 20 provides the correct pump compatibility without adapting a generic regulator. Its 3/4" bypass connection allows the regulator to be incorporated into the P40's bypass/return plumbing configuration.
Why Replace a Comet P40 Pressure Regulator?
The pressure regulator controls operating pressure and manages bypass flow within the P40 system. A worn, damaged, or malfunctioning regulator can interfere with proper pressure control and bypass operation.
Replacing it with the OEM Comet GCP 20 regulator restores the original regulator configuration designed for the new-style P40 pump.
