“Over the Sheave” hoses from Parker Parflex Division are designed for demanding applications such as fork-lifts, booms, aerial lifts, cranes and tree de-limbers. Nothing is more extreme or harder on hoses than continual flexing, especially in very cold temperatures. And nothing is more important than the safety of the operators working near them.

These products are designed to withstand the very harsh environments associated with continual flexing over sheaves at the minimum bend radius. All hoses have the highest abrasion resistance jackets on the market and meet the lowest industry cold flex temperatures. In addition, these hoses are 70% lighter than competitive rubber products and the clean thermoplastic core gives best in class chemical compatibility and, unlike rubber hose, do not erode due to high fluid velocity.

Parker’s “Over the Sheave” line includes light weight, super duty wire reinforced and hose for extreme situations in sizes from 1/8” up to 1”, depending on hose selection.

  • Light Weight Fiber Reinforced (53DM & 55LT): Designed to operate in temperatures from -70ºF to 212ºF.
  • Super Duty Wire Reinforced (560 & 590) operate in temperatures from -40ºF to 250ºF.
  • For the absolute extreme situations, H6 hose meets SAE 100R17 and operates in temperatures ranging from -70ºF to 250ºF.
