500 Bar Wire Braided High Pressure Hose – 50 MPa Working, 1500 Bar Burst
The wire braided high pressure hose in this range is a steel-wire reinforced rubber hose rated at 50 MPa (500 bar) working pressure with a published burst pressure of 1500 bar, supplied for high pressure cleaning and hydraulic assemblies.
50 MPa equals 500 bar, or about 7250 psi. A 1500 bar burst figure gives a 3:1 burst-to-working ratio, which is a familiar safety factor for this class of hose. The product is listed under the high pressure hose accessory category and is used to carry water between a pump, a valve and a trigger gun or lance. This page explains what the three pressure numbers mean, which dimensions still need confirming, and where this hose does and does not belong.

Working pressure, burst pressure and construction come from the published description. Inner diameter, hose length, fitting type, minimum bend radius, temperature range, impulse life and approved media are not stated, so they are not invented. A hose assembly is only as strong as its end fittings – confirm the whole assembly rating, not just the hose.
Where a 500 Bar Hose Assembly Is Used
Pressure Washer Gun and Lance Lines
The hose between the pump outlet and the trigger gun must be rated above the machine maximum pressure. A 500 bar hose comfortably covers domestic and light industrial washers in the 70-150 bar class, and gives margin for pressure spikes when the trigger closes.
Hydraulic and Water Jetting Assemblies
Wire braid reinforcement resists the pulsation produced by plunger pumps. In a water jetting skid, the hose must be matched to the fitting, the bend radius and the medium; water, hydraulic oil and hot water do not share the same rubber compound approvals.
Replacement and Spare Lines
A hose with cuts, blisters, kinked braid, corroded fittings or weeping at the ferrule should be replaced rather than repaired. Because the published description does not list end fittings, order a complete rated assembly or a hose plus matched fittings from the same supplier.
Working Pressure, Burst Pressure and Safety Factor
Working pressure is the pressure the assembly is designed to carry continuously, while burst pressure is a destructive test value. The 3:1 ratio here is a design margin, not permission to operate at 1500 bar, and not a substitute for a pressure relief valve. Pressure spikes from a closing trigger, pump pulsation and water hammer all eat into that margin.
The 500 bar rating also defines where the hose stops. It is not suitable for 1000 bar marine water blaster and 1500 bar ultra-high-pressure unit and 2800 bar / 40000 psi hull preparation system, which require dedicated ultra-high-pressure hose, fittings and lance assemblies rated for their own working pressure.
Finally, check flow. A hose that is too small in bore for 8-25 L/min will waste pump power as friction and heat, and a hose that is too large is heavy and hard to handle. Confirm the bore, length and fitting thread from the dimensional drawing before specifying an assembly. For systems with a pump and motor joined by a shaft coupling, also check GIUNTI ELASTICI flexible coupling on the drive side.
| Duty | Selection point | Equipment |
|---|---|---|
| Domestic 70-100 bar washer line | Working pressure above machine maximum | portable 70 bar washer, KQ-1008S 100 bar washer |
| 150 bar petrol washer line | 500 bar hose gives margin | gasoline pressure washer |
| General high pressure assembly | 500 bar / 50 MPa working | This hose |
| 1000-2800 bar water blasting | Dedicated UHP hose required | 1000 bar water blaster, 40000 psi water blaster |
Operating and Maintenance Notes
- Never operate near the 1500 bar burst figure; 500 bar is the continuous working limit.
- Use matched, rated end fittings and have assemblies made or inspected by a competent hose supplier.
- Respect the minimum bend radius and protect the hose from vehicle wheels, sharp edges and heat.
- Inspect for blisters, exposed braid, ferrule movement and weeping before each use; replace damaged assemblies.
- Fit a pressure relief or unloader valve so a closed trigger cannot dead-head the pump.
Frequently Asked Questions
Is 50 MPa the same as 500 bar?
Yes. 1 MPa equals 10 bar, so 50 MPa is 500 bar, or about 7250 psi. The psi figure is a unit conversion.
Does a 1500 bar burst rating mean I can run at 1000 bar?
No. 1500 bar is a destructive test value. The continuous working rating is 500 bar, and ultra-high-pressure systems need hoses designed for their own working pressure.
What fittings does the hose use?
End fittings and threads are not published. Order a complete rated assembly or confirm the fitting standard with the supplier.
Can it carry hot water or hydraulic oil?
Temperature and medium limits are not published. Confirm the rubber compound and approvals before using anything other than cold water.
