SCREW TO CONNECT
ZERO LEAKAGE COUPLINGS
Heavy duty service conditions in construction plant,
machinery and vehicles. High pressure pulse
applications and agricultural machinery.
Connect without ingress of air and disconnection
without loss of fluid.
Screw connection mechanism avoids use of locking
balls and so eliminates the risk of Brinelling (the
problem of locking ball indentation in the nose of the
Can be connected by hand with up to 20 bar
pressure in each hydraulic hose line and up to
50 bar with hand tools.
Hardened carbon steel body, zinc plated, nitrile seals.
The couplings are connected by screwing the Female
(fixed half) and Male (swivel half) couplings together
until the limit stop is reached.
CONNECTION / DISCONNECTION UNDER
Connection and disconnection by hand, with up to 20
bar residual pressure in the line is possible. Above this
hydraulic coupling whilst under full system pressure
can be very dangerous and should not be attempted
