590TJ | Parker Parflex Thermoplastic Hose

The Parflex 590TJ (TOUGHJACKET™) hose is ideal for large-scale, heavy-duty applications such as construction equipment, agriculture equipment and transportation. This compact, lightweight hose is designed for a very low length change under pressure, which makes it ideal for boom or cable track applications where long lengths are required. The abrasion resistant cover and durable wire construction allow the Parker 590TJ hose to handle the strains of the most demanding applications.

Parker's TOUGHJACKET™ hose covers are designed with a material that exceeds the abrasion resistance of comparable hoses by more than 100%. These rugged polyurethane hose covers also feature a low length change under pressure (+/- 2%).

The 590TJ TOUGHJACKET™ hose is available in twin-line and multi-line bonded configurations. These problem-solving assemblies simplify the installation process, allow for smooth operations, and improve the overall strength and stability of the hose to eliminate many of the problems that lead to hose failure. With a resilient, abrasion resistant cover and up to 5,000 psi constant working pressure, this TOUGHJACKET™ solution has the ability to transform and enhance current systems.

Note: Parker's Parflex division has announced a new resin approved for use in the manufacturing of their Hybrid 2.0 and TOUGHJACKET™ hose. The addition of this new copolyester inner tube material will allow Parker to insure a stable supply of product for customers. Hoses that are made with this material will meet the same specifications that can be found in the current 4660 catalog and will not change in form or function. This change will begin in November 2017 and is expected to be fully implemented in 2018.
