Product Description:
The SAE 100R8 / EN 855 R8 / ISO 3949 Type R8 thermoplastic hydraulic hose is designed for modern hydraulic systems requiring lightweight, flexible, and reliable performance. It features a thermoplastic inner tube resistant to petroleum-based, synthetic, and water-based hydraulic fluids, reinforced with high-strength synthetic fiber layers, and protected by a durable thermoplastic outer cover. Non-conductive orange versions are available for applications near high-voltage equipment, providing operator safety and system reliability.
Construction:
Tube:
oil-resistant Nylon/Polyamide (PA) or Copolyester
Reinforcement:
two textile braids
Cover:
oil, water, heat, abrasion, weather, and ozone-resistant Nylon/Polyamide (PA) or Polyurethane/PU/TPU
Temperature Range:
-40°C to +100°C (-40°F to +212°F), intermittent up to +125°C (+257°F)
Applications:
Suitable for mobile and industrial hydraulic systems handling petroleum-based, synthetic, and water-based fluids.
