Quick Overview：
The SL321 EN853 2ST Hydraulic Hose, also known as a two-wire braided hydraulic hose, medium- to high-pressure hose, or SAE 100R2AT hose, is engineered for reliable hydraulic fluid transfer in medium- to high-pressure applications. It handles petroleum-based, water-based, and biodegradable fluids while operating from -40°C to +100°C (-40°F to +212°F). With strong resistance to oil, abrasion, and weathering, and a flexible design for tight installations, it is available in 3/16" to 2" (DN5–DN50) sizes. It is widely used in excavators, backhoe loaders, hydraulic lifts, and concrete mixers, helping operators achieve efficient, safe, and long-lasting hydraulic performance.
