ULTRAFLEX
NOTICE
This table is only indicative.
ULTRAFLEX cannot be held responsible for the pipe choice, since the installer must do this according
to the operating pressure.
WARNING
ULTRAFLEX UP Series pumps are provided with a valve protecting them against overpressure when
the pressure is higher than about 70 bar (1000 PSI).
The references to the standards are updated at the date of issue of this document. The installer must
make sure that there are no other updates.
3.10.3 Hose connection to the system for models UP39-I R and UP45-I R
1 Connect the rigid pipes ( 12 mm external diameter) to connect the pump to the cylinder.
2 If one or more additional steering stations are installed (except the pumps series "NV"), use the kit OB
120 U-2S by following the suitable instructions.
Position 3/8" straight unions (1) as indicated in the picture.
Put some fitting sealant type Loctite 542 or Loctite 545 on the thread. Fit and screw manually the fittings (3)
until they are completely inserted; then tighten them with a 7/16" open end wrench with a torque of 17.6 Nm
(156 lb ft).
WARNING
Do not use teflon tape or adhesive tape. Pay attention to the sealant positioning: if it is inserted into the
system, it could block it and make it unusable.
