About the Premium Quick Connect Set Control your water flow with the Premium Quick Connect Set. This combination tool securely connects your hose to the Unger HydroPower On/Off Valve, the XERO Premium Quick Connect Push to Fit Set, and finally to your 5/16" water fed hose. Simply push the XERO Push to Fit Straight Fitting onto your 5/16" hose to assemble. To release the hose, push down on the plastic push-button. This useful setup can help you conserve your precious pure water when you want to put your pole down for a few minutes to readjust. For best results, use this on the end of the XERO 3/8" Rubber Hose to connect your purification system to your 5/16" pole hose. Connecting it directly to your system can cause it to break more easily. ***5/16" hose not included PRODUCT INCLUDES: XERO Premium Quick Connect Push to Fit Set - 5/16 Inch Unger On/Off Valve
