Double-Wire Braid Hose SAE 100R2 / EN 853 2SN | Two high-tensile steel-wire braids | Approximately 140–400 bar (2,030–5,800 psi), depending on bore size | Approximately −40°C to +100°C (−40°F to +212°F) | Petroleum-based hydraulic oils and selected water-based fluids approved for the hose construction | Higher pressure capability and improved resistance to external abrasion compared with single-braid hose | Construction machinery, hydraulic cylinders, excavators, forklifts, industrial power units | Use the correct fittings and assembly method; bend radius and impulse performance are critical for long service life. |
Compact Two-Braid Hose SAE 100R16 / EN 857 2SC | Two steel-wire braids with a compact construction | Approximately 160–400 bar (2,320–5,800 psi), depending on bore size | Approximately −40°C to +100°C (−40°F to +212°F) | Petroleum-based hydraulic oils; compatible water-glycol and biodegradable fluids subject to manufacturer approval | Smaller outside diameter and tighter minimum bend radius than many conventional two-wire hoses | Space-limited installations, compact mobile equipment, articulated machinery, complex hose routing | Useful where routing space is restricted, but the specified minimum bend radius must not be exceeded. |
Four-Wire Spiral Hose SAE 100R12 / ISO 3862 4SP | Four alternating layers of high-tensile spiral steel wire | Approximately 210–420 bar (3,045–6,090 psi), depending on bore size and standard | Approximately −40°C to +121°C (−40°F to +250°F) | Petroleum-based hydraulic oils and approved fire-resistant or biodegradable hydraulic fluids | High impulse resistance and reliable performance in demanding high-pressure systems | Heavy construction equipment, mining machinery, high-pressure hydraulic drives, industrial presses | Typically less flexible than braided hose; select fittings and assemblies rated for the same pressure class. |
Six-Wire Spiral Hose SAE 100R13 / ISO 3862 6SP | Six alternating layers of spiral steel wire | Approximately 350–420 bar (5,075–6,090 psi), depending on bore size | Approximately −40°C to +121°C (−40°F to +250°F) | Petroleum-based hydraulic oils and other fluids specifically approved for the tube and cover materials | Very high pressure and high impulse capability for severe-duty applications | Large excavators, mining systems, steel mills, heavy lifting systems, high-pressure equipment | Requires careful routing, adequate clamping, and correctly matched fittings because of its stiffness and weight. |
Textile-Braid Hydraulic Hose SAE 100R3 / SAE 100R6 | Textile braid, with hose construction varying by applicable standard | Approximately 20–80 bar (290–1,160 psi), depending on type and bore size | Approximately −40°C to +100°C (−40°F to +212°F) | Petroleum-based hydraulic oils and selected low-pressure water-based fluids | Lightweight, highly flexible, and suitable for low-pressure return, pilot, and control lines | Return lines, instrumentation circuits, lubrication systems, small machinery, low-pressure controls | Do not substitute for high-pressure wire-reinforced hose; verify the exact standard and pressure rating. |
Suction and Return Hose SAE 100R4 / EN ISO 3949 Applications | Textile reinforcement with embedded steel helix or anti-collapse structure | Usually suction service to approximately −0.8 bar and low-pressure return service typically up to 10–20 bar | Approximately −40°C to +100°C (−40°F to +212°F) | Petroleum-based hydraulic oils; some biodegradable oils and water-based fluids require specific compatibility confirmation | Resists collapse under vacuum and accommodates large flow rates with relatively low restriction | Tank-to-pump suction lines, reservoir return lines, drain lines, circulating oil systems | Never use a standard pressure hose for pump suction unless it is specifically designed and rated for vacuum service. |
Thermoplastic Hydraulic Hose SAE 100R7 / SAE 100R8 | Synthetic-fiber braid, commonly with a thermoplastic tube and cover | Approximately 70–350 bar (1,015–5,075 psi), depending on construction and bore size | Approximately −40°C to +93°C (−40°F to +200°F) | Petroleum-based hydraulic oils; certain water-glycol, phosphate-ester, and biodegradable fluids when specifically approved | Small outside diameter, low fluid permeation, clean appearance, and good resistance to abrasion | Material handling, lift platforms, compact hydraulic systems, pilot lines, robotics, control circuits | Temperature and fluid compatibility can vary considerably; check the tube material and electrical-conductivity requirements. |
PTFE-Lined Hydraulic Hose SAE 100R14 | PTFE inner tube with braided stainless steel or other metallic reinforcement | Approximately 70–210 bar (1,015–3,045 psi), depending on bore size and braid | Approximately −54°C to +260°C (−65°F to +500°F), with pressure derating at elevated temperatures | Mineral oils, many synthetic fluids, water-based fluids, and a broad range of chemicals when PTFE and fittings are compatible | Excellent chemical resistance, low friction, and high-temperature capability | Hot-oil systems, chemical processing, high-temperature hydraulic circuits, gas and fluid transfer | PTFE has limited resistance to bending fatigue and external crushing; follow the specified bend radius and assembly procedure. |
