High Pressure Jack Hose

High Pressure Jack Hose Overview

High Pressure Jack Hose is listed for compact high-pressure hydraulic lines used with jack and lifting equipment. The published product information identifies a 700 bar application reference, a polyester elastomer inner tube and a black polyurethane cover. Final hose selection must be checked against the exact hose size, fittings, assembly method, pressure cycle and equipment manufacturer requirements.

Published Product Details

• Application reference: high-pressure hydraulic lines up to the published 700 bar value, subject to complete assembly verification.
• Inner tube: polyester elastomer.
• Cover: black polyurethane, non-pinpricked, with white ink-jet branding.
• Published temperature range: -40°C to 100°C (-40°F to 212°F); the existing product information limits air and water-based fluids to 70°C (158°F).
• Published vacuum rating: -0.93 bar / -700 mm Hg / -13.5 psi / -27.5 in Hg. Confirm applicability for the selected hose and assembly.

How to Confirm a 700 Bar Hose Selection

A pressure figure printed on a product page must not be treated as approval for every assembly. The hose, end fittings, ferrules, crimp specification, adapters and equipment connection must be reviewed as one system.

Confirm the Complete Hydraulic Circuit

Provide the normal working pressure, possible pressure spikes, operating cycle, fluid, temperature and equipment model. The allowable assembly pressure is governed by the lowest-rated component and the verified assembly procedure.

Fluid and Temperature Review

The existing listing refers to petroleum, synthetic and water-based hydraulic fluids. Compatibility must still be confirmed using the fluid name, concentration, Safety Data Sheet and operating temperature. Do not assume that a broad fluid category confirms compatibility with every formulation.

Temperature Limits Need Context

Review both fluid and ambient temperatures, including heat near pumps, engines or hot surfaces. For air or water-based fluids, use the published 70°C limitation only after confirming the exact hose and manufacturer data.

Fittings and Assembly Rating

End connection type, thread standard, sealing method, orientation and required length should be confirmed before fabrication. A fitting that looks similar may use a different thread form or sealing face.

Routing and Installation

Allow adequate bend radius and movement, keep the hose away from sharp edges and heat sources, and avoid twist during tightening. Support the hose without restricting normal movement. Protective sleeves or guards may be considered where abrasion or hose-whip exposure exists.

Inspection and Safe Use

High-pressure hydraulic systems store hazardous energy. Before inspection or replacement, support the load independently, stop and isolate the pump, release trapped pressure and follow the equipment manufacturer’s lockout procedure. Never work beneath an unsupported load or search for a leak with bare hands.

Remove Damaged Assemblies from Service

Inspect for cover damage, exposed reinforcement, kinks, crushed areas, leakage, loose fittings or unusual movement. Quarantine a suspect assembly and have it assessed by competent personnel; do not attempt an improvised repair.

Information Required for an Engineering Review

• Equipment make, model and connection details
• Required hose bore, overall length and fitting orientation
• Working pressure, pressure spikes and duty cycle
• Hydraulic fluid name, concentration and SDS
• Fluid and ambient temperature range
• Thread, sealing face and adapter requirements
• Routing, bend, movement and abrasion conditions
• Required test, identification or documentation

Send these details to Advtech Engineering for a configuration review. Product suitability should be confirmed against the actual operating conditions before installation.
