Fluid transfer & Hydraulic application
Danfoss' L7000 Series stainless steel quick disconnect
coupling is a full-flow coupling suited for applications
where maximum flow capacity is required and valving
is not needed. Mainly used in fluid transfer applications
and offers excellent corrosion resistance.

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.
