Our FF series flat face quick couplings are high-pressure hydraulic connectors designed according to ISO 16028 international standard. Made of high-strength carbon steel and equipped with standard BSP thread, these couplings provide fast connection, perfect sealing, and zero leakage performance under extreme working pressure. They are widely used in construction machinery, hydraulic tools, industrial equipment, and agricultural machinery requiring frequent connection and disconnection.
Material & Quality
The entire body is forged from premium carbon steel with high hardness, strong pressure resistance, and excellent deformation resistance. The surface is treated with advanced plating to achieve anti-rust, anti-corrosion and wear-resistant performance. With high-quality internal sealing components, the couplings remain stable and leak-free under long-term high-pressure operation.

Main Advantages
1. Stable 350 Bar High Pressure Performance
The 1/2” FF quick coupling supports a maximum working pressure of 350 Bar. Under full-range rated pressure conditions, the coupling maintains stable structure without deformation, swelling or bursting. It perfectly adapts to high-pressure hydraulic systems and heavy-duty mechanical environments.
2. 100% No Oil Leakage
Thanks to the precise flat-face valve structure and upgraded sealing system, the coupling never leaks oil during continuous high-pressure work, connection or disconnection. It effectively avoids oil waste, system air intake, and equipment failure caused by poor sealing.
3. Precise BSP Thread for Universal Fit
Adopts standard BSP thread with accurate tooth shape, tight locking, and strong compatibility. It fits most hydraulic hoses and equipment worldwide for easy installation and quick replacement.
4. Durable Carbon Steel Structure
Integral forging carbon steel body ensures high impact resistance, long service life, and stable performance even under frequent plugging and harsh working conditions.
应用程序
Suitable for excavators, loaders, road rollers, hydraulic tools, industrial hydraulic systems, agricultural machines and all kinds of high-pressure fluid pipelines that require fast, safe, and leak-free connection.
