Danfoss Hansen L7000 Series steel quick disconnect coupling is a full-flow coupling with a rugged construction. Similar to the Danfoss H5000 Series, the heat treatment and
hardened materials give the coupling excellent resistance
to mechanical and hydraulic demands. It is suited for applications where maximum flow capacity is a requirement
and valving is not needed.

European Pressure Equipment
Directive*
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.

Flow Data
The nominal flow diameter of the coupling has no impact on pressure drop, as
it is wider than the circuit diameter.
