Connect Under Pressure, Multi-Purpose Quick Couplings (Hydraulic, Fluids) up to 4,500 psi - Snap-Tite PH Series Couplers

Brand: Parker Hannifin

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.

PH Series Couplers (hydraulic, fluid) up to 4,500 psi connect with valved H Series Nipples, while PH Series Nipples connect with valved H Series Couplers. 

It is recommended that only one half of the connection (coupler or nipple) be PH version, not both. Parker's PH Series have poppet valves with an added pressure relief feature to allow connection under static pressures up to 3000 psi. 

With a PH Series Coupler installed on a pressurized line you can easily connect with a mating valved H Series Nipple.
