High Pressure, High Flow, Steel Quick Couplings with Sleeve Lock – HO Series

Description

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.
