R12 hose is a four-layer steel wire helical reinforced hydraulic hose that complies with the SAE J517 100R12 (corresponding to ISO 3862 R12) standard. Its core positioning is "high pressure, pulse resistance, and resistance to harsh working conditions". The following is a brief description from multiple dimensions:
Inner rubber layer: Mostly nitrile rubber (NBR), resistant to mineral oil and hydraulic oil corrosion, ensuring pure medium transmission.
Reinforcing layer: Four layers of high-strength steel wire are spirally wound, which is the core of its high-pressure and anti-pulse performance, and can resist fatigue cracking caused by frequent pressure fluctuations.
Outer rubber layer: Commonly used are chloroprene rubber (CR) or ethylene propylene diene monomer rubber (EPDM), which are wear-resistant, ozone-resistant and UV-resistant, and suitable for outdoor/industrial oily environments.
Pressure: Working pressure 2500-4000 psi (172-276 bar, decreasing as size increases), burst pressure is four times the working pressure, suitable for high-pressure hydraulic systems;
Temperature: Conventional -40 °C to + 100°C, can tolerate higher temperatures in the short term, suitable for high and low temperature outdoor/workshop scenarios.
Compatibility: Mainly compatible with mineral-based hydraulic oil. Some special inner rubbers can be compatible with food-grade hydraulic oil (FDA certification required).
Construction machinery: Oil cylinders for excavators/cranes, vibration motor pipelines for rollers;
Mining and metallurgy: Hydraulic supports, high-pressure circuits for breakers;
Industrial equipment: Injection molding machine clamping cylinder, hydraulic press pipeline;
Special scenarios: The flame-retardant model with MSHA certification is used in underground mines, and the FDA-certified model is used in food processing equipment.
