Features
Hight pressure hoses 700 – 1000 – 1800 – 2500 – 2800 bar
These hoses are suitable for all hydraulic applications and consist of 2, 4, or 6 steel wire spirals (depending on the operating pressure) which are extremely resistant to traction. Their outer polyurethane (700 bar) or polyamide (1800 and 2500 bar) cover provides excellent scraping protection and excellent efficiency is guaranteed in case of minimal expansions during operations. All the hoses with the two couplers are equipped flushed a with ISO VG 32 oil.

The maximum operating pressure of the pump-hose-coupling system is the working pressure of the lowest rated part.
Bolt tensioner hoses: SN##FT (with K13X coupler)
Torque wrenche hoses: SQ##FM (male coupler on one side and female coupler on the other)
The oil volume required to fill the hoses needs to be taken into account when selecting the pump model.
Hight pressure twin hoses 700 bar
These hoses are suitable for torque wrenches and double acting cylinders (oil return), they are composed of two steel spirals extremely resistant to traction. The external polyurethanecovering guarantees an excellent protection to abrasions and scrapings while the minimum exercise expansions ensure the maximum efficiency of the system. All the hoses with the two couplers are equipped flushed a with ISO VG 32 oil. All the hoses ending with double couplers are already flushed with ISO VG 32 oil.
