Fluid transfer & Hydraulic application
Danfoss' L7000 Series brass 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 where
stainless steel is not a requirement, it can vehicle a wide
range of media and offers good corrosion resistance.

*Nominal diameters over 25 mm should not be used to convey gases in Group 1
(as per PED 2014/68/EU).
European Pressure Equipment
Directive*
All couplings 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 should not be used to convey
gases in Group 1 (hazardous).
* Group 1 = Hazardous media / Group 2 = Other media
Applications & Markets
• Pressure Washing
• Steam-Cleaning Equipment
• Fluid Transfer Lines
• Refrigerant Circuits
• Applications where
maximum flow capacity
is required

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