Premium Hoses for High-Pressure Applications

HANSA-FLEX has developed a hydraulic hose line series for high pressures and extreme applications up to 450 bar (6,527 psi). The hose line series consists of the Long Life spiral hose HD700LL, a continuation of the development of hose type HD700, and the newly designed PAH700 series of swage fittings. The premium fittings compliment the range offered by HANSA-FLEX as a leading manufacturer in the hydraulics field.

Long Life spiral hose HD700LL is designed for extreme loads: With a pressure carrier consisting of six steel wire spiral coils and a high temperature- and ozone-resistant outer layer, it can withstand the highest pressures, while under extreme conditions. The interlock fitting series PAH700 in steel is designed to withstand time. A CrVI-free zinc-nickel coating protects the product against corrosion. The new hose line series is designed for a long service life, and the extended replacement interval also reduces associated costs.

Corrosion resistance of these premium fittings against red rust has been investigated in salt spray tests in accordance with DIN EN ISO 9227. The coating achieved a resistance of more than 1,200 hours before the appearance of red rust on the main body. The high-pressure load capability of the premium hose line series was also tested and certified for up to 2 million pressure impulse cycles, exceeding all the requirements of standard SAE 100 R15.

The hose lines are available in sizes DN31 to DN51. The HD700LL hose can be combined with fittings from the PA700PLUS series. This has the effect of making additional connection geometries available.
