High Temp Wire Spiral Hydraulic Hose Assembly 4 layers For Heavy Machinery

Our high-temperature wire spiral hydraulic hose assemblies are engineered for heavy machinery operating in extreme heat environments. With 4 layers of high-tensile steel wire spiral reinforcement, they deliver 500,000+ impulse resistance and stable performance from -40℃ to +120℃, ideal for mining, oilfield and construction equipment under continuous high-temperature working conditions.

1. Ultra-High Pressure & Burst Resistance
4 layers of high-tensile steel wire spiral reinforcement deliver extreme pressure-bearing capacity, supporting working pressure up to 445 Bar, ensuring 100% safe operation in heavy-duty hydraulic systems of excavators, breakers and mining equipment.
2. Industry-Leading Impulse Fatigue Resistance
Passes 400,000–500,000 impulse tests (far exceeding industry standards), with exceptional fatigue performance, suitable for long-term continuous heavy-duty operation, effectively extending equipment service life and reducing maintenance costs.
3. Wide Temperature & Extreme Environment Adaptability
Operates reliably from -40℃ to +120℃ (intermittent 125℃), adapting to extreme cold, high heat, and harsh outdoor conditions in construction, mining and oilfield industries, outperforming ordinary hoses in extreme environments.
4. Seamless & Durable Structure Design
Seamless extruded synthetic rubber inner tube (no joints, uniform thickness) ensures stable fluid transmission and superior oil resistance; anti-abrasive synthetic rubber cover withstands oils, fuels, mechanical wear and atmospheric corrosion, doubling service life in harsh working conditions.
5. 100% Leak-Proof Precision Connection
Equipped with no-skive high-precision fittings (DPF4T/DPX4XX series), easy installation, tight connection, zero leakage, eliminating safety risks and downtime caused by hose failure.
6. Multi-Media & Multi-Scenario Compatibility
Suitable for mineral oil, biological oil, glycol-water, water, lubricants and other hydraulic fluids, fully meeting the diverse fluid transmission needs of construction machinery, mining equipment, oilfield operations and general industrial systems.
7. Global Certification & Standard Compliance
Strictly manufactured in accordance with GB/T 10544, SAE 100R12, BS EN 856, ISO and other international standards, certified by MSHA, BV, IATF 16949, ISO 9001, etc., ensuring global quality and reliable supply for domestic and export markets.
8. Full Customization Service
Customizable length, inner diameter, fitting type, logo and packaging, compatible with almost all heavy machinery models, providing one-stop customized solutions for different customer needs.
