Application Scenarios

It is used for steering pump oil suction flexible connection of 5-ton wheel loaders, suitable for earthwork, quarry mining, sand yard and bulk cargo loading high-intensity working conditions.

• Manufactured strictly according to OEM standards, hose length and inner diameter fully match the original assembly, direct installation without cutting or secondary processing, saving assembly time.
• Multi-layer fiber reinforced structure, good tensile performance, not easy to crack under bending and vibration.
• Excellent oil-resistant rubber formula, resist long-term erosion of hydraulic oil, slow aging rate, not easy to swell or soften.
• Good flexibility, can absorb vibration between rigid pipes, reduce fatigue damage of joints and adjacent pipe fittings.
• Smooth inner wall, low flow resistance, stable oil supply, avoid turbulence and air entrainment.
• Weather-resistant outer rubber, resist dust splash and atmospheric aging, adapt to complex outdoor working conditions.

FAQ 

Q1: Can this low pressure rubber hose be used for high-pressure oil circuits?
A1: No. It is only designed for low-pressure suction circuits. High pressure will cause hose expansion, burst and oil spraying.

Q2: What are the common failure forms of the rubber hose?
A2: Rubber aging and hardening, cracking, swelling after oil soaking, abrasion rupture, loosening at connection.

Q3: What should be noticed before installation?
A3: Check whether the hose inner cavity is clean; insert the hose fully onto the pipe nipple; align the hose clamp and control tightening torque properly.

Q4: Can the hardened and slightly cracked hose continue to be used?
A4: No. The structural strength has declined, it is easy to crack and leak under vibration, replace it immediately.

Q5: What will happen if the hose is bent below the minimum bending radius?
A5: Excessive bending will crush the inner channel, increase oil resistance, accelerate local rubber fatigue and early damage.

Q6: How to maintain the rubber hose in daily use?
A6: Regularly check the surface condition, oil seepage and fastening of hose clamps; keep the hose away from sharp edges.
