Not all pressure washer hoses are built the same. If you own a petrol pressure washer or clean large, tough surfaces regularly, you may need a very high PSI hose to handle the force safely. This guide explains what counts as “very high PSI,” why it matters, and which hose type is best for your machine.
What Counts as a Very High PSI Hose?
A hose is considered very high PSI when it can safely handle:
- 3,000–4,000 PSI (heavy-duty petrol washers)
- 4,000–6,000 PSI (commercial units)
These hoses are built with stronger internal layers and often feature steel-braided reinforcement.
Do You Need a Very High PSI Hose?
Choose a very high PSI hose if you:
- Use a petrol washer above 3,000 PSI
- Clean driveways, brick, stone, or concrete regularly
- Use turbo nozzles or rotary surface cleaners
- Need maximum durability and kink resistance
Electric washers do not require very high PSI hoses.
Benefits of High PSI Hoses
- Higher durability — withstands intense pressure
- Longer lifespan — ideal for frequent use
- Safer performance — reduces risk of bursts
- Kink-resistant (especially steel-braided)
Standard vs High PSI Hose Materials
PVC or Rubber Hoses (Standard)
- 1,500–2,800 PSI
- Good for electric washers
- Lightweight but less durable
Steel-Braided Hoses (Very High PSI)
- 3,000–4,000+ PSI
- Heavy-duty and long-lasting
- Best for petrol washers
Commercial-Grade Dual-Braided Hoses
- Up to 6,000 PSI
- Maximum toughness
- Ideal for professionals
PSI Ratings: What To Match
| Washer PSI | Recommended Hose PSI |
|---|---|
| 1,500–2,000 | 2,000 PSI hose |
| 2,000–3,000 | 3,000 PSI hose |
| 3,000–4,000 | 4,000 PSI hose |
| 4,000–6,000 | 6,000 PSI hose |
Important: Never use a hose with a lower PSI than your washer. It can burst.
Best Lengths for High PSI Hoses
- 30 ft (9 m): small patios & general use
- 50 ft (15 m): driveways & garages
- 75–100 ft: commercial jobs or large outdoor spaces
