Very High Pressure Hydraulic Hoses

Very high pressure hydraulic hoses are designed for specialised systems where the operating pressure and service conditions require a hose specifically rated for the application. They are used in selected hydraulic jacking systems and other demanding industrial operations. Water-blasting hoses are also used for high-pressure water delivery, but they must be selected for the intended water-jetting service rather than assumed to be interchangeable with hydraulic oil hoses.

Hydrofit Engineers lists Jack Hose and Water Blast Hose variants identified as 30, 40, 45 and 50 in its existing hydraulic hose range. The exact pressure ratings, sizes and intended service for each variant should be confirmed against the applicable product datasheet before publication or selection.

Types of Very High Pressure Hoses

Hydraulic Jack Hose

Hydraulic jack hoses are used in compatible hydraulic jacking equipment and systems where controlled fluid delivery is required to operate lifting or force-generating equipment.

When selecting a jack hose, the hose’s working pressure must meet the equipment requirement, and the end connections must match the jack, pump or hydraulic power unit. Hose routing, length, bending restrictions and the manufacturer’s operating instructions should also be considered.

A jack hose should never be selected solely because its outside appearance or connection resembles an existing hose. Confirm the pressure rating and compatibility of the complete assembly.

Water Blast Hose

Water blast hoses are intended for specified high-pressure water delivery and water-jetting applications. The hose construction and end connections must be appropriate for the equipment, water pressure and service conditions.

Hydrofit’s listed range includes Water Blast Hose 30, Water Blast Hose 40, Water Blast Hose 45 and Water Blast Hose 50. These names are retained here as product identifiers; they should not be treated as verified pressure ratings without the relevant datasheets.

Water-blasting hoses should not be confused with hoses intended for hydraulic oil circuits. The media, connections and service requirements must match the intended application.

Technical Specifications

Very high pressure hose specifications are highly dependent on the product series and size. Use the following table as the specification structure for the landing page, and populate the values from the actual product documentation.

Parameter	Specification to confirm
Product family	Hydraulic Jack Hose or Water Blast Hose
Model or series	Exact product designation
Nominal bore	Available internal diameters
Outside diameter	Manufacturer’s size-specific value
Working pressure	Verified rated working pressure
Maximum allowable pressure	As defined by the product documentation
Burst pressure	Published manufacturer value
Reinforcement	Exact construction stated by the manufacturer
Inner tube or hose material	Confirmed material and media compatibility
Outer cover	Material and environmental resistance, where applicable
Temperature range	Product-specific rating
Minimum bend radius	Product-specific minimum
End connections	Compatible connection type and pressure rating
Intended medium	Hydraulic fluid or water, as applicable
Applicable standard	Exact standard or specification declared for the model

The working pressure, burst pressure, size range and temperature limits should not be estimated from the product name. Use the model-specific documentation to complete this table.

Applications of Very High Pressure Hoses

Depending on the specific product and its approved use, these hose types may be considered for:

Hydraulic jacking and lifting equipment
Specialised industrial hydraulic systems
High-pressure water-blasting equipment
Industrial cleaning and surface preparation using compatible water-jetting equipment
Other pressure-intensive applications supported by the hose manufacturer’s specifications

The suitability of a hose for any application must be confirmed from its rated pressure, medium compatibility, fittings and operating conditions.

How to Choose a Very High Pressure Hose

The consequences of selecting an incorrectly rated hose can be serious. Check the following before placing an order:

Confirm the application: Identify whether the hose will carry hydraulic fluid or water for blasting.
Verify working pressure: Use the equipment manufacturer’s requirement and the hose’s rated working pressure.
Match the connections: Check the connection type, size, sealing arrangement and pressure rating of every component in the assembly.
Check the hose size and routing: Confirm the bore, required length, bend radius and installation layout.
Check operating conditions: Verify fluid or water compatibility, temperature, external abrasion and environmental exposure.
Use a correctly rated assembly: Hose, end fittings and assembly method must be suitable for the application as a complete unit.

Safety and Inspection

Very high pressure systems require particular attention during installation and operation. Use only hoses and assemblies rated for the intended service. Inspect them for abrasion, cuts, exposed reinforcement, leaks, deformation and damaged connections, and replace them in accordance with the manufacturer’s instructions.

Never check a suspected leak with your hand, and never loosen a connection while the system is pressurised. Depressurise and isolate the equipment before inspection or maintenance, following the equipment manufacturer’s safety procedure. A hose that looks intact may still be unsuitable if it has been damaged, incorrectly assembled or used beyond its rated limits.
