High Pressure Hydraulic Hose. SAE 100R12 hydraulic hose for petroleum and water-based hydraulic fluid. It contains 4 spiral plies of heavy wire wrapped in alternating directions. One braid or ply of material may be used over the inner tube and/or over the wire reinforcement binding the synthetic rubber to the wire. Reinforced with four high tensile steel spirals, this hose is designed for hydraulic systems with high peak pressures and arduous operating conditions. The special synthetic cover is designed to resist hydraulic oil, weather, and abrasion. The synthetic rubber tube is resistant to mineral, vegetable, and glycol based hydraulic oils. A MSHA cover is available. 3/8" to 2" ID -40°F to 248°F (257°F intermittent)
