Parker Hannifin, the global leader in motion and control technologies, has expanded the Parflex hydraulic hose line with the family of TOUGHJacket™ hydraulic hoses, designed to withstand the strains of large-scale, heavy-duty applications. The new hoses, featuring special Parker-formulated polyurethane jackets to meet industry requirements for highest abrasion resistance, exceed the abrasion resistance and durability of super enhanced rubbers by more than 100%.
These compact and light-weight hoses also offer ultra-low length change under pressure and superior UV resistance. The 563TJ hydraulic hose series offers the best change in length characteristics at +/-1%. This makes it an ideal solution for boom or cable track applications where long lengths are required because abrasion and length change are the biggest contributors to hose failure. The SAE acceptable change in length specification is +2% to -4%. Most hoses shrink at least 2% in a constrained environment which can be disastrous for the hose and cable tracks. If 100 feet of hose is run in a boom, it must accommodate for the extra four feet of hose that will be required due to shrink or run the risk of the hose pulling the fitting off the hose or destroying the cable track.
