FF Series couplings are widely used in the public utility market where hydraulic oil spillage can constitute a serious safety hazard, particularly in overhead bucket hoists that are used for maintenance of high-voltage power transmission lines.

These couplings are also used for quick change of hydraulic tools in construction, railway maintenance and mining industries. The ease of cleaning makes them ideal for use in these types of hostile environments.

Features:

1. New valve design, it can resist damage from highly flow and the pressure of impulse, provide advance performance.

2. Sleeve mechanism is designed to help prevent dirt from entering the internal mechanism to cause faulty operation when connecting or disconnecting. 

3. FF Series couplings employ flush valving when connecting or disconnecting. This means only small amount of fluid can be lost during disconnection or air inclusion during re-connecting.

4. Zn-Ni Plating provides advanced anti-rust performance.

5. FF Series conforms to standard of ISO16028.
