FEM and FEC Series Nipples (hydraulic) up to 5000 psi, connect with FEM Series Couplers. All FEM and FEC Series parts meet or exceed design and performance requirements of Hydraulic Tool Manufacturer's Association (HTMA - ISO 16028) standards.
Parker's FEM Series quick connect fittings are double shut off, non-spill, flat face quick couplings designed to minimize spillage and air inclusion when connecting or disconnecting and are interchangeable with other products complying with HTMA - ISO 16028. FEM quick couplers and nipples are available in a range of sizes as well as male and female fitting ends to be versatile for use in applications with pressures up to 5000 psi.

FEC nipples are designed to connect under pressure, in situations where fluid lines contain residual pressure caused by thermal expansion. The FEC Series connect-under-pressure rating ranges from 1500-3000 psi dependent on body size.

• All sizes are globally interchangeable with other couplings complying with HTMA (ISO 16028) standards

• Non-spill, flat face valves minimize fluid loss when disconnecting, to reduce environmental contamination and avoid safety hazards caused by spillage.

• Flat face valves minimize the amount of air that can enter the system when connecting fluid lines, thus preventing accelerated wear of the system's components.

• Male bulkhead fitting ends for panel or plate mounting options

• FEC nipples provide the ability to connect under residual pressure caused by thermal expansion.

• Optional sleeve lock guards against accidental disconnection


• Skid loader attachments

• Hydraulic tools

• Construction equipment attachments

• Industrial hydraulic lines

• Agricultural implements

• Coolant fill and drain lines - Contact QCD for a brass, FEM style drain port nipple that is recommended for use by the Technology and Maintenance Council of the American Trucking Association, TMC Recommended Practice 353
