Roofster III P40 Regulator

Replacement Pressure Regulator for Roofster III P40 Soft Wash Systems

Direct OEM replacement regulator for the Roofster III P40 soft wash machine. Controls outlet pressure to the soft-wash gun so you can dial in dwell time and chemical application rate without flooding the surface.

Specs at a Glance

• Compatible System: Roofster III P40 soft wash unit
• Function: Adjustable pressure regulation
• Type: OEM replacement

When to Replace

• System will not hold steady pressure at the gun
• Regulator knob slips or freezes
• Internal leaks at the regulator body
• Inconsistent chemical application rate even at the same setting

Why OEM

The Roofster III P40 is a tuned system. Aftermarket regulators may fit the threads but rarely match the original pressure curve, which throws off your chemical dilution downstream. Use the OEM regulator for predictable results.

Pair With

Schedule a full P40 service kit at the same time if the system has 200+ hours on it. Diaphragm and seal replacements are cheaper than a second teardown.
