TP8TN
ISOLATOR
R8 NON CONDUCTIVE TWIN HOSE
RECOMMENDED FOR:
RYCO TP8TN ISOLATOR TWIN Hose consists of two TP8N Series Hoses of the same size, permanently joined together in a flat compact form that can be easily reeled onto payout and return reels on forklifts and cranes. It is also used for hydraulic powered hand tools, such as loppers and chain saws, and other applications requiring two hoses. TP8TN is used where electrical non-conductivity is required (for use
in applications where there is potential for contact with high voltage sources). Suitable for use with mineral, vegetable and most ester based hydraulic fluids. Heat and hydrolysis stabilised for use with water based hydraulic fluids up to +70°C (+158°F). Suitable for use with some gases, fluids and chemicals (contact RYCO Hydraulics Technical Department). Smooth inner tube for high flow rate; and smooth, easily cleaned cover. The aramid reinforcement gives TP8TN
Hose excellent corrosion and fatigue resistance, and low elongation of ±2% at maximum dynamic working pressure.
PERFORMANCE:
Meets or Exceeds the Performance Requirements of: AS 3791 100R8, EN 855 Type R8, ISO 3949, SAE 100R8.
TUBE:
White, oil resistant seamless thermoplastic (Polyester).
REINFORCEMENT:
One or two braids of aramid fibre.
COVER:
Orange, oil and abrasion resistant thermoplastic (Polyurethane). Cover is non-perforated.
FEATURES:
Meets non-conductivity requirements of SAE 100R7,
AS 3791 100R7, EN 855 Type 7 (maximum leakage does not exceed 50 μA when subjected to 75 kV/305 mm or 250 kV/m for 5 minutes). Incorrect storage and use, particularly that leading to oil or moisture entering the reinforcement, may adversely affect electrical properties.
TEMPERATURE RANGE:
From -40°C to +100°C (-40°F to +212°F). Air & Water +70 ˚C (+158 ˚F).
For water, emulsions etc. see page 58.
WORKING PRESSURE:
Maximum working pressures are based on 4:1 safety factor (maximum working pressure to minimum burst pressure).
