Danfoss Gromelle H5000 Series steel quick disconnect
coupling is a pull to connect double shut-off coupling.
Featuring the original profile, it remains as the series users
prefer when it comes to severe hydraulic application such
as high pressure, pressure impulses, heavy mechanical
loads and frequent connection and disconnection cycles.
The unique sleeve lock option offers a reliable solution
and benefit to the end user when safety is a concern.
H5000 Series
(Steel)
Product Features
• Proprietary pro昀椀le
• Pull-to-connect with double shut-o昀昀 valving
• Ball-locking
• Optional safety sleeve lock prevents accidental disconnections
• The heat treatment of the plug and use of
high strength steel for the socket sleeve
provide superior mechanical and hydraulic
performance The design of the valve gives
the coupling increased robustness when
disconnected.
• Optional dust caps and plugs (made of
anodized aluminum)
• Pressure performance
• Standard body material: Zinc trivalent steel
• Standard seal material: NBR, FKM, EPDM

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