SAE100R12 four-layer steel wire spiral high-pressure hose assembly manufacturer
1. Product Overview: SAE100R12 Four-Steel-Wire Spiral High Pressure Hydraulic Hose Assembly
Letone SAE100R12 four high-strength steel wire spiral hydraulic hose assembly is equipped with bilingual technical documents in Chinese and English. Developed for heavy-duty high-pressure working conditions such as construction machinery and forest & agricultural machinery, it serves as a core matching assembly for hydraulic pipelines in high-pressure hydraulic systems.
The complete hose assembly consists of a three-layer composite rubber tube body and matched metal joints. Each layer of the rubber tube is specially customized for harsh operating environments: the inner tube is made of black heat-resistant oil synthetic rubber, which resists swelling and corrosion when conveying various hydraulic media for a long time. The middle reinforcement layer adopts four layers of high-strength spiral steel wires, greatly improving the pressure resistance and pulse resistance of the assembly to buffer instantaneous hydraulic impact. The outer layer is a weather and oil resistant synthetic rubber protective layer, blocking outdoor sunlight, muddy water and oil contamination to significantly extend the service life of the whole hose assembly.
This hose assembly features a wide temperature adaptation range, operating stably from -40℃ to +121℃ without hardening, cracking or leakage of the rubber tube under high and low temperatures. It boasts excellent medium compatibility, capable of transporting water-based hydraulic oil, petroleum-based hydraulic oil and biodegradable eco-friendly hydraulic oil, meeting the pipeline supporting demands of most hydraulic equipment.
2. Complete Specifications & Core Performance Parameters
Leotne SAE100R12 hose assembly includes 8 standard diameter sizes ranging from -6 to -32, marked with both inch and millimeter dimensions, covering mainstream pipeline sizes from 3/8 inch to 2 inches. The pressure resistance varies by specification: small-diameter assemblies (-6 to -16) deliver stronger pressure resistance with a maximum working pressure of 28MPa; size -20 has a maximum working pressure of 21MPa; large-diameter assemblies (-24, -32) have a maximum working pressure of 17.5MPa. All specifications adopt a test pressure standard twice the working pressure and a burst pressure standard four times the working pressure, ensuring sufficient safety margin for the hose assembly.
The parameter table records the inner diameter range, reinforcement outer diameter range, hose outer diameter range, minimum bending radius and unit weight of each rubber tube, facilitating hose assembly processing, joint selection and equipment pipeline layout planning.

3. Segmented Application Scenarios
Letone SAE100R12 four steel wire spiral hose assembly is designed for heavy-duty harsh working conditions, widely matched with hydraulic systems of construction, forestry and agricultural machinery.
Construction Machinery: Excavators, loaders, road rollers and cranes require high-pressure hose assemblies for booms, buckets and traveling mechanisms. Construction and mining sites are filled with dust and muddy water; equipment operates with continuous vibration and frequent hydraulic pressure shocks. The four-layer steel wire structure provides excellent fatigue resistance and burst resistance, effectively reducing pipeline leakage and equipment downtime.
Forestry Machinery: Loggers and wood grapplers work outdoors all year round, mostly using biodegradable hydraulic oil under drastic temperature changes and intense UV radiation. The weather-resistant outer rubber layer prevents aging and cracking, with outstanding medium compatibility to support long-term continuous operation of forestry equipment.
Agricultural Machinery: Large tractors, harvesters, tillers and plant protection machines face drastic temperature fluctuations, heavy mud and oil contamination in farmlands. Some agricultural equipment adopts anti-freeze water-based hydraulic media. The full range of specifications matches steering, lifting and oil supply systems, adapting to all-year farm operation in northern and southern China.
In addition, this series of hose assemblies can be matched with high-pressure hydraulic pump stations and hydraulic tools. Small-diameter assemblies are used for high-pressure control oil circuits, while large-diameter assemblies serve as main oil supply pipelines, featuring strong versatility for complete machine matching.
