Parker Quick Couplings
Connect Under Pressure, Multi-Purpose Quick Couplings (hyd, fluids) up to 4,500 psi - Snap-tite PH Series Couplers
Parker's general purpose connect under pressure quick couplers and nipples are versatile for use across a spectrum of applications where fluid lines require fast and easy connection and disconnection while under residual pressure
Snap-tite PH Series Couplers (hydraulic, fluid) up to 4,500 psi connect with valved Snap-tite H Series Nipples. It is recommended that only one half of the connection (coupler or nipple) be PH version, not both.
Parker's Snap-tite PH Series have poppet valves with an added pressure relief feature to allow connection under static pressures up to 3000 psi. With a Snap-tite PH Series Coupler installed on a pressurized line you can easily connect with a mating valved Snap-tite H Series Nipple. PH Couplers and nipples are available in 3/8", 1/2" and 3/4" sizes with other sizes available by request.
