IMPORTANT
Connect only high-pressure hoses (ø 4.1 x
2.3 mm) with threaded sleeve and hose
studs may be connected to the inlet fitting
and to the check valves with reinforced
collar.

Fig. 5 Check valve with knurled collet and pressure plastic tube
Low-pressure range (secondary metering device)
Connect the pressure plastic tube (ø 6 x 1.5 mm) to the check
valve with standard collet (knurled collet) and to the inlet
fittings towards the lubrication point (knurled collet).

NOTE
Exceptionally the high-pressure hose
(ø 4.1 x 2.3 mm) with threaded sleeve and
hose stud may also be used for the low-
pressure section. Applications for construc-
tion machines or agricultural machines,
however, require the use of check valves
and inlet fittings (towards the lubrication
point) with reinforced collet for the low-
pressure range. Refer to Parts Catalog.
The pressure plastic tubes are marked with white lines
(Fig. 5) as an installation aid.
 Cut the pressure plastic tube off at one of the white lines
before it is mounted. Then insert the plastic pressure tube
into the fitting up to the next white mark. This will ensure a
correct installation of the pressure plastic tube in the
threaded tube fitting.

Protection Cap for Push-in Type Fittings
To prevent dirt from entering the systen, the push-in type
fittings, check valves and pressure relief valves can be
equipped with protective caps.
