Pressure Relief Valve&Quick Disconnect Fit for Zodiac Polaris Pool Cleaner - 9-100-9002 Relief Valve and D29 UWF Quick Disconnect Wall Fitting Kit

9-100-9002 Pressure Relief Valve: When the pressure inside the line exceeds the spring tension, the spring opens and relieves the excess pressure. Screwing it all the way in can provide the maximum amount of pressure and speeds it up. D29 UWF Quick Disconnect: This is the main body of the wall fitting that does a twist-lock into the pool wall. Attach to the D29 quick disconnect module, which prevents high water pressure from damaging your pool sweep robot. Compatible with Polaris pool vacuum models 180, 280, 380, 480 PRO, 3900 Sport. Easy to install, unscrew the old part and screw in the new part. Important: Please kindly check the compatibility and specifications before ordering
