Eaton Introduces the MLFF Series Flat Face Coupling for Hydraulic Applications

To: Eaton® Gromelle™& Hansen™ Distributors - EMEA

Eaton is proud to announce the introduction of the new MLFF Series Stainless Steel Flat Face Quick Disconnect Coupling product line. The MLFF Series is a dry break quick disconnect coupling for use in hydraulic applications. The MLFF coupling halves are manufactured using 316 stainless steel and are designed for use in aggressive environments when couplings manufactured from carbon steel are not suitable. The most common uses for the MLFF are in oil and gas, steel mills, and construction applications. The MLFF series meets the ISO 16028 standards and is interchangeable with other coupling products that meet this standard.
