Oil Hose
About Oil Hose
An oil hose is a specialized flexible conduit designed for transferring petroleum-based fluids, lubricants, hydraulic oils, and diesel fuels under various pressure conditions. According to industry standard definitions, a genuine oil hose consists of three critical layers: an inner tube resistant to oil degradation, a reinforcement layer (either Wire Braided Hose or Wire Spiral Hose construction), and a protective outer cover. These rubber hose assemblies are essential in applications where static or dynamic pressure conditions demand reliability and safety.
As a professional High Pressure Hose manufacturer in China, HENGHUA produces oil hose solutions that meet international certifications. The typical oil hose features an NBR (nitrile rubber) inner tube, providing exceptional resistance to petroleum-based fluids across temperatures from -40°C to +125°C. Whether you need bulk industrial supply or custom hose assembly solutions, understanding the technical specification of your oil hose is critical for system longevity and operational safety. To buy the correct oil hose, you must evaluate working pressure, bend radius, and fluid compatibility.
Comprehensive Oil Hose Product Specifications
1. Size Range and Dimensional Options
HENGHUA’s oil hose series covers inner diameters from 3/16 inch to 4 inches (5mm to 102mm), accommodating low-flow instrumentation circuits to high-volume fuel transfer systems.2. Working Pressure and Safety Factors

The NBR inner tube resists hydraulic oils, diesel, gasoline, crude oil, and lubricants. Optional FKM tubes add compatibility with phosphate esters and high-temperature fluids.8. Flexibility and Bend Radius Engineering
Our Wire Spiral Hose maintains flexibility at high pressures due to optimized helical wire angles (54°44′ standard). A 1-inch oil hose achieves a minimum bend radius of 5 inches (127mm).9. Durability Metrics: Abrasion, Corrosion, Weather
MSHA-accepted covers resist oil swelling, ozone cracking, and UV degradation. Abrasion resistance exceeds 200 cycles on Taber abraser testing.10. Continuous Operating Temperature Range
Standard oil hose: -40°C to +125°C (-40°F to +257°F). High-temperature variants reach +150°C continuous.11. Construction and Material Breakdown
Inner Tube Layer: NBR synthetic rubber (or FKM/PTFE for special media). Smooth bore minimizes flow resistance and prevents particle entrapment. Reinforcement Layer (Critical Feature):- Wire Braided Hose: Single or double layers of high-tensile steel wire braided at precise angles. Ideal for medium-pressure hydraulic systems with frequent flexing.
- Wire Spiral Hose: Four or six layers of counter-rotating spiral-wound wire. Handles extreme pressures and constant pulsing in heavy equipment.
- Design principle: Spiral construction distributes stress evenly, while braided construction offers superior kink resistance.

Step 3: Measure required bend radius and routing length
Step 4: Select fittings (crimped fittings for permanent, reusable fittings for field repair)
Step 5: Add protective sleeves or guards for abrasion or fire risks
Installation Warnings
Never twist oil hose during installation (mark alignment line)
Maintain bend radius at least 10x hose OD
Use proper adapters and flanges for port connections
Torque fittings to specification (over-tightening damages threads)
Maintenance and Inspection
Monthly checklist:
Check cover for cuts, abrasion, or swelling
Inspect crimped fittings for slippage or corrosion
Feel for hard spots or soft sections (indicates liner degradation)
Monitor for pinhole leaks (use cardboard, not hands)
