FF Series Couplers (hydraulic) up to 5000 psi, meet the requirements of Hydraulic Tool Manufacturer's Association (HTMA - ISO 16028) standards in the 3/8" size, and connect with FF/FC Series Nipples. FC Nipples provide the ability to connect under pressure.
Parker's FF Series are double shut, off non-spill quick couplings designed to minimize spillage and air inclusion when connecting or disconnecting. Couplers have a sleeve locking mechanism to help prevent accidental disconnection. Couplers and nipples are available in a range of sizes to be versatile for use in applications with pressures up to 5000 psi.
