Frequently Asked Questions

It fits regulator assemblies 223621, 208082, and 223622. If your sprayer uses one of these assemblies, the housing is compatible. Review your unit’s parts catalog or serial-based breakdown before ordering.

Compatibility with aftermarket regulator parts is not guaranteed. Using OEM components is recommended to maintain proper regulator operation.

Damage can result in leaks, unstable pressure, diaphragm failure, and inconsistent spray output. Replacing the housing restores proper regulator sealing and structural support.
