Overview

The SG-DCG4000FSC is General Pump's Hammerhead compensating surface cleaner trigger gun, the new gray-style unit rated to 4000 PSI, 8 GPM, and 300°F. It's the replacement trigger for flat surface cleaners, with a 3/8 FNPT inlet and 1/4 FNPT discharge. This gray compensating version supersedes the older black, non-compensating SF-DG4000FSC — the compensating design balances pressure across the cleaner's dual arms for even, consistent cleaning. Built for hot-water use, it fits pro operators running surface cleaners on concrete, sidewalks, and flatwork who need to swap out a worn or failed trigger gun.

Frequently asked questions

Yes. The SG-DCG4000FSC (gray, new style) supersedes the black, old-style non-compensating SF-DG4000FSC. If you're replacing a worn trigger on a Hammerhead surface cleaner, this is the current version.

A compensating trigger balances pressure across the surface cleaner's spinning arms so both nozzles run evenly. The older black version was non-compensating; this gray unit adds that balancing.

The inlet is 3/8 FNPT and the discharge is 1/4 FNPT. Confirm your surface cleaner's plumbing matches these threads before ordering.

Yes. It's rated to a maximum temperature of 300°F, so it works with hot-water surface cleaning as well as cold, up to 4000 PSI and 8 GPM.
