Discharge Hose Tube Reinforced Rubber Abrasion Resistant With Long
Service Life
Description
Built to withstand extreme internal pressure surges and resist
chemicals, this hose is the definitive choice for high-pressure
cleaning, water blasting, and industrial washdown. Its smooth bore
ensures minimal pressure loss from the pump to the nozzle, directly
translating to higher cleaning efficiency and lower energy costs.
( Case: A German automotive plant using standard hoses for factory
washdown faced frequent failures and pressure drops at the nozzle.
After adopting our High-Pressure Hose, they achieved a 15% increase
in cleaning efficiency due to consistent pressure, and hose-related
downtime was eliminated for over 18 months. )

Product Features
High Pressure Reinforcement
Multiple high-tensile synthetic fiber braids (e.g., polyester)
provide extremely high burst pressure ratings (e.g., up to 2500 PSI
and beyond), ensuring safety and reliability during intense
cleaning operations.
Smooth Non Stick Bore
A seamless, thermoplastics or EPDM inner tube minimizes friction
and turbulent flow, ensuring maximum pressure and velocity are
delivered to the cleaning nozzle for faster, more effective
results.
Oil Chemical Resistant Cover
The outer cover is made from a specialized compound that resists
degradation from oils, greases, solvents, and common industrial
cleaning chemicals, preventing cover softening and cracking.
Exceptional Flexibility Kink Resistance
Designed with a focus on maneuverability, the hose remains flexible
even in cold conditions and under high pressure, reducing operator
fatigue and preventing dangerous pressure spikes caused by kinking.
Applications
Industrial Cleaning
High-pressure water blasting for removing rust, paint, and deposits
from machinery, tanks, and surfaces; routine factory washdown.
Agriculture
High-pressure sprayers for cleaning milking parlors, animal pens,
and heavy farm machinery to maintain hygiene standards.
Firefighting Emergency Response
Suitable as a delivery hose for high-pressure pumps on industrial
firefighting units and for disaster relief washdown operations.

FAQ
1. Q: What is the difference between a water blasting hose and a
standard pressure washer hose?
A: Our industrial-grade hoses feature higher-quality
reinforcements, thicker covers, and superior chemical resistance,
making them far more durable and safe for continuous professional
use compared to consumer-grade hoses.
2. Q: Is the hose suitable for use with hot water and steam?
A: Our standard high-pressure hose is rated for hot water up to
85°C (185°F). For true steam cleaning applications, we offer a
dedicated steam hose with different construction.
3. Q: How do I ensure the hose lasts as long as possible?
A: Always release pressure from the hose after use, avoid dragging
it over sharp edges, and store it coiled in a cool, dry place away
from direct sunlight.
4. Q: What is the maximum working pressure for this hose?
A: The maximum working pressure varies by model, diameter, and
reinforcement. Standard hoses range from 150 PSI (10 bar) for
general use to over 1500 PSI (100 bar) for high-pressure
applications. Always check the specific product's data sheet for
its exact rating.
