Comet GCP 20 Pressure Regulator 42001-00838 for New P40, 300 PSI

The Comet GCP 20 regulator (42001-00838) controls working pressure on the new-design Comet P40 soft-wash pump, up to about 300 PSI. It is built with chemical-resistant materials for bleach and surfactant service and a 3/8" NPT connection.

This part is for the new-design Comet P40 diaphragm pump. The P40 is a common choice for soft-wash rigs, rated around 11 GPM at up to 300 PSI with chemical-resistant wet parts. Check the Comet P40 breakdown sheet to confirm the part and position number for your pump before ordering.

A working pressure gauge is the easiest way to tell if your pump, regulator and tips are performing normally. Rising pressure can point to a clogged tip or line; dropping pressure can mean a worn valve, air leak or failing regulator. Glycerin fill damps the needle so the reading stays steady on a vibrating pump or skid.
