Hansen W6000 Series
Steel Couplings
Danfoss Gromelle W6000 Series steel quick disconnect couplings use a thread-to-connect design for fluid transfer and hydraulic service where heavy mechanical loads, hydraulic shocks, and severe pulsating pressures are part of the job.
Thread-to-connect couplings for severe hydraulic service
The W6000 Series is a steel quick disconnect coupling family built around a rugged thread-to-connect design. It remains a go-to choice for severe hydraulic applications such as construction and mining, where resistance to ram loads, hydraulic shocks, and pulsating pressure matters.

For pulsating pressures when disconnected, apply a multiplier of 0.5. Rated-flow values are based on a 1 bar / 14.5 psi pressure drop. When connecting under pressure, the socket nut thread must be lubricated.
