BHydraulics Connect Under Pressure Couplings Hydraulic Quick Couplings 5000 Series Features The Parker 5000 Series coupling features: � Two-piece coupler body that permits operation while one or both halves are under pressure as well as when there is no pressure in either half. � Connect under pressure by unscrewing the valve body until two or three threads are visible. � Nipple can be inserted and locked into the coupler without opening either valve. (Use a wrench to thread the valve body back into the coupler, the valves are opened against internal pressure. If internal pressure makes manual disconnect difficult, unscrewing the valve body from the coupler will permit the valves to close, thereby relieving internal pressure and allowing manual operation of the ball- locking sleeve.) Applications Performance The Parker 5000 Series is an economical coupling that is a 5000 Series (1/2") PSIDinPressureDrop threaded union and can be connected under pressure with Test Fluid: Oil - 200 SUS 300 300 tools. For applications that require a coupling to be connected under-pressure and where tools can be used to make the 200 200 connection, the 5000 Series coupling should be considered. 100 100 90 90 80 80 Note: Protective dust plugs and caps play a crucial role in the 70 70 60 60 life of a quick coupling and no purchase of a hydraulic quick 50 50 coupling is complete without the selection of an appropriate 40 40 dust plug and cap. See pages noted in Table of Contents for 30 30 dust plugs and caps for the Parker full line of hydraulic couplings. 20 20 10 10 9 9 8 8 7 7 6 6 5 5 Specifications 4 4 3 3 Body Size (in.) 1/2 Rated Pressure (PSI) 2500 2 2 Rated Flow (GPM) 12 Temperature Range (std seals) -40� to +250�F 1 1 1 2 3 4 5 6 7 8 910 20 30 Flow in USGPM Quick Coupling Division 8145 Lewis Road � Minneapolis, MN 55427 B-42 www.parker.com/quickcouplings
