OurFaster FFH Flat Face Quick Disconnect Couplings are designed to offer a secure and leak-free connection in hydraulic systems. These couplings feature a flat-face design that minimizes contamination and spillage, making them ideal for critical applications where preventing leaks is crucial. They have a high maximum working pressure of 5076 psi (35 MPa) and come with a durable Zinc-Nickel Plating for enhanced protection. While most sizes in the FFH Series are interchangeable with other ISO 16028 couplers, the 1/8" size and the 1.25" size have specific surface treatments and are not ISO interchangeable.
