Parker Quick Couplings
High Pressure, Unvalved, Steel Quick Couplings with Sleeve Lock (hydraulic) up to 15,000 psi - HO Series Couplers

Parker's high pressure and high flow quick couplers are ideal for use with high pressure hydraulic applications where fluid lines require fast and easy connection and disconnection while providing maximum flow and low pressure drop.

 

 

HO Series Couplers (hydraulic) up to 15,000 psi connect with HO Series Nipples.
Parker's HO Series are high pressure, steel, high flow quick couplings with manual sleeves. Couplers and nipples are unvalved, resulting in straight through, unrestricted flow. Electroless nickel plating provides corrosion resistance and sleeve lock guards against accidental disconnection.
