Polaris UWF Restrictor Kit (380/280/180)
The pressure restrictors are designed to work in combination with the pressure relief valve. Together they will release excess excess water pressure so that the Polaris can operate at its optimum level of efficiency. The red pressure restricture offers maximum water restriction. The blue restrictor offers less restriction.
This UWF Restrictor kit is only required if the cleaner is operating above the recommended RPM.
