HYDRAULIC HOSE ASSEMBLIES

120J… JACK HOSE

Hose

A typical jack hose is 1 ⁄ 4 " I.D. with 3 ⁄ 8 " male pipe ends and is usually 6 feet long. One pipe (NPT) end threads into the hydraulic hand pump, while the other end usually threads into a hand tool hydraulic nipple. A hydraulic coupler is usually threaded into the ram. Remember that even though 120J Jack Hose is rated to 10,000 psi, jacking applications are static pressure situations at ambient temperature. DO NOT USE 120J Jack Hose Assemblies for impulsing or regular hydraulic applications. Please note, many manufacturers claim that their jack hose meets the Material Handling Institute IJ100 standard for jack hose. In fact, this standard was withdrawn several years ago and is no longer in effect.

Tube : Seamless oil resistant nitrile rubber. Reinforcement : Two high tensile steel wire braids. Cover : Oil, abrasion, and weather resistant black or blue synthetic rubber. Temperature Range : -40°C (-40°F) to 100°C (212°F), petroleum base fluids intermittent to 125°C (257°F). Fittings & Assembly : Use only Pulsar 4216 solid male pipe (NPTF) stems. DO NOT USE JIC, BSP, or other hydraulic threads, as they may not be suitable for these pressures. All hoses must be crimped to the recommended crimp dimensions – visit: www.pulsarhydraulics.com/crimp-specifications for the most up-to date specifications. Use strain relievers to minimize hose flexing at the coupling; TPG-530 will fit 1 ⁄ 4 " assemblies and TPG-725 will fit 3 ⁄ 8 " assemblies. Hose assemblies should include safety warning tags (120J-TAG).
