Pressure Washer Hose
A Pressure Washer Hose is a specialized rubber hose designed to transmit high-pressure hot or cold water in heavy-duty cleaning equipment. Following a strict standard of construction, this High Pressure Hose features a black oil-resistant synthetic rubber tube, one or two high-tensile steel wire braids, and a black abrasion and weather-resistant synthetic rubber cover.
The definition of a quality Pressure Washer Hose lies in its ability to withstand extreme conditions. It operates from -40°C to +121°C (-40°F to +250°F), making it a true Wire Braided Hose for thermal endurance. As a Wire Spiral Hose alternative, the braided design offers superior flexibility for daily cleaning tasks.
Key performance highlights include a working pressure up to 40 MPa (5800 psi) and a burst pressure of 160 MPa (23200 psi), ensuring a 4:1 safety factor. Core advantages are its ozone/weather resistance, abrasion-resistant cover, availability as a pre-made hose assembly, and compatibility with both hot and cold water.
This rubber hose is the Solution for industries needing reliable Service. It is used on construction sites, agricultural facilities, manufacturing plants, and by municipal Service teams. It solves the core pain points of hose burst from pressure spikes, cover damage from dragging on concrete, and stiff handling in cold weather.
As a leading manufacturer in China, we provide a traceable quality guarantee. Every hose length is proof-tested, and we offer full Support including custom hose assembly with crimped fittings, reusable fittings, adapters, or flanges. Optional protective sleeves and guards extend hose life in harsh environments.

Structure and Materials
Tube (Inner Layer): Black oil-resistant synthetic rubber. Provides excellent compatibility with hot water, cold water, and mild chemicals. Ensures low flow resistance and prevents medium contamination.
Reinforcement (Middle Layer): One or two high-tensile steel wire braids. This Wire Braided Hose design balances strength and flexibility. The braided angle (typically 54°44′) optimizes pressure distribution and kink resistance.
Cover (Outer Layer): Black abrasion and weather-resistant synthetic rubber. Formulated to resist ozone, UV radiation, and mechanical damage from dragging or impact.

Precise Selection Professional Guide
Hose Assembly Solutions
We supply complete hose assembly options to save you time and reduce leak points. Choose from:
- Crimped Fittings: Permanent, leak-free connection for maximum reliability. Ideal for bulk orders.
- Reusable Fittings: Field-attachable, perfect for emergency repairs or custom lengths.
- Adapters: Convert between thread types (NPT, BSP, JIC) for compatibility.
- Flanges: For high-flow, high-pressure connections.
- Protective Sleeves & Guards: Add abrasion resistance near sharp edges or high-traffic areas.
Why Buy A Pre-Assembled Hose?
Factory-crimped assemblies guarantee correct crimp dimensions, eliminate field-assembly errors, and include pressure testing. This is especially critical for 2-braid hoses operating at 5800 psi.
Pressure Washer Hose vs. Standard Hydraulic Hose
| Feature | Pressure Washer Hose | Standard Hydraulic Hose |
|---|---|---|
| Temperature Range | -40°C to +121°C | -40°C to +100°C (typical) |
| Water Compatibility | Excellent (hot/cold) | Poor (degrades tube) |
| Abrasion Cover | Heavy-duty | Standard |
| Flexibility | High | Medium |
Always use a dedicated Pressure Washer Hose for water-based cleaning. Hydraulic hoses are not designed for continuous hot water flow.

- Match fittings correctly to the hose specification.
Operation:
- Stay within rated working pressure and temperature.
- Allow hot water to flow briefly before full pressurization to warm the hose.
- Never exceed burst pressure, even momentarily.
Maintenance:
- Inspect cover daily for cuts or abrasion.
- Check crimped fittings or reusable fittings for leaks.
- Replace hose if outer wire is visible or if the cover is deeply gouged.
Frequently Asked Questions (FAQ)
Q1: Can I use this hose for steam?
A: No. Maximum temperature is +121°C (+250°F). For steam, a special rubber hose is required.
Q2: What is the cost difference between 1-braid and 2-braid?
A: 2-braid has higher price due to extra steel wire, but offers nearly double the working pressure. Request a bulk quote for discount.
Q3: Do you supply hoses with fittings already attached?
A: Yes. We offer hose assembly with crimped fittings, reusable fittings, or adapters per your request.
Q4: Can I get a pdf technical datasheet?
A: Yes. Contact our Support team to download the full specification sheet.
