ZY-FF Series
ZY-FF ISO 16028 flat face couplings for public utilities, overhead bucket hoists, construction, railway maintenance, mining, and hydraulic tools.
Features
- The new valve design resists high flow and impulse pressure.
- The rotating sleeve locking mechanism helps prevent accidental disconnection.
- The sleeve mechanism helps keep dirt out and incorporates a spring dust seal.
- Hardened nipples, sleeves, and solid bar stock improve impact resistance.
- A bonded nitrile/PTFE anti-blowout seal supports severe service.
- The durable ball-locking mechanism provides reliable connection and reduces hose torque.
- Flush valving minimizes fluid loss and air inclusion.
- Environmentally conscious zinc plating improves corrosion resistance.
- The ZY-FF Series conforms to ISO 16028.
- Compatible with PARKER FE/FF, STUCCHI A8008, AEROQUIP FD89, and HANSEN QA2900 series.
