Quick coupling for high pressure hydraulic circuit
DN 5 - 9, 180 l/min, 720 bar | HP Holmbury

HP Series couplings have been designed for use in
systems working at pressures up to 720 bar. There
are two basic sizes, the A5HP and A9HP.
One of the most important benefits of these couplings
is ‘no fluid spillage on disconnection’.
The high flow ratings of these couplings make them
ideal for use with high pressure motorised power
units, particularly when low pressure loss is
important.
APPLICATIONS
High pressure plant and equipment operating on
mineral oil. Rail industries, torque wrenches and bolt
tensioners.
UNIQUE SAFETY FEATURE
HP Series couplings incorporate a unique safety
feature to prevent accidental disconnection - a spring
loaded locking sleeve. When the coupling halves are
connected, the locking sleeve automatically rotates
through 90°. To disconnect the coupling the locking
sleeve is turned back 90° so the locking ball is
aligned with the release notch. The sleeve is then
pulled back and the coupling will disconnect.
