Fluid transfer & Hydraulic application
Global region
Danfoss Gromelle W6000 Series steel quick disconnect
coupling is a thread-to-connect with a rugged
construction. It remains the series users refer to when it
deals with severe hydraulic applications, such as
construction and mining. The design and materials used
give this quick disconnect coupling resistance to heavy
mechanical loads. Most common examples are ram
loads, hydraulic shocks and severe pulsating pressures.

Couplings with nominal diameters up to
and including 25 mm are designed and
manufactured under Article 4.3 of the
European Pressure Equipment Directive
PED 2014/68/EU. Couplings with nominal
diameters greater than 25 mm are designed
and manufactured in accordance with the
stipulations of Module A of the European
Pressure Equipment Directive PED 2014/68/
EU. They should not be used to convey
unstable gases.
