Hydraulic hose Hyperline FX AS

for gasPTFEanti-static

When electrically resistive fluids like solvents and fuels, or multiphase mixtures are passed through natural PTFE hose at high flow rates, a static charge build up occurs on the inner wall of the PTFE liner. This can discharge to the nearest conductor (e.g. SS braid) that creates a pin-hole in the PTFE liner resulting in a leak-path. Antistatic PTFE includes a small quantity of a special high purity carbon black, which ensures safe static charge dissipation in accordance with International Standards. Antistatic Hose Assemblies When “AS” (Antistatic) grade hose is specified the hose or hose assembly supplied will be tested in accordance with EN ISO 8031 to meet the Antistatic requirements of EN 16643. This requires, for an antistatic liner or antistatic cover, that the resistance between an appropriately placed foam electrode and a metallic end fitting will be between 103 to 108 ohms per assembly. For hose assemblies which meet these requirements an appropriate Grade “Ω” marking is applied in accordance with EN 16643 if requested. Note: When in service, at least one end fitting must be connected to earth, to permit dissipation of the static charge from the end fitting. EC - ELECTRICAL CONTINUITY (Also known as ‘Electrically Bonded’ & 'M' grade) All Hyperline FX hose assemblies are electrically continuous, except AM (Aramid Fibre) and TO (Tube Only) grade hose assemblies. Electrical Continuity requires that the hose assembly supplied is electrically continuous, or conductive, between metal end fittings at each end of the hose (whether GP or AS grade).
