Adjustable Brass Chemical Injector

The Dayton 1MCZ8 is an adjustable chemical injector built with a brass body for pressure-washing systems. It accepts a 3/8 inch BSP discharge connection and is designed for professionals who need precise chemical metering during high-pressure cleaning jobs.

Pressure and Flow Limits

Rated for a maximum discharge pressure of 4000 psi and a maximum flow rate of 4 gpm, this injector operates within those boundaries. Exceeding either limit can damage the internal mechanism or reduce injection accuracy, so the pump and nozzle selection must stay inside the stated range.

Installation Notes

The unit threads directly onto a compatible 3/8 inch BSP discharge port on AR North America pumps or the listed Grainger part numbers. Leaks usually come from worn O-rings or mismatched thread types, and the adjustable knob can seize if chemical residue is not flushed after each use.

Questions about this item

Which adjustable chemical injector should I choose for 4000 psi and 4 gpm systems?

The Dayton 1MCZ8 is built for exactly 4000 psi and 4 gpm, with a 3/8 in BSP discharge connection and brass body, so it matches those ratings directly.

What does the 4000 psi rating mean when the injector is installed on a pressure washer?

It means the injector can handle the full pump pressure up to 4000 psi without leaking or failing, while still drawing chemical at the rated 4 gpm flow.

How does the 3/8 in BSP discharge connection affect compatibility with my hose and wand?

The 3/8 in BSP thread is a standard pressure-washer fitting, so it connects directly to most 3/8 in BSP hoses, wands and quick-connects without adapters.
