The version of the HYPERLINE hose without a braid (Tube Only) is externally spiral corrugated (right-handed) and internally smooth. The hose combines the advantages of a flexible corrugated hose and a smooth-walled hose with undisturbed flow. The standard version is made of natural, semi-transparent PTFE, allowing for visual flow monitoring. The antistatic AS version made of carbon-filled Teflon (black) ensures the dissipation and dispersion of electric charges for substances and conditions at risk of static electricity. The hose material meets FDA requirements (21 CFR 177.1550 for the standard hose, 21 CFR 178.3297 for the antistatic version). It is flame-retardant (UL94 V-0) and has a high oxygen index (LOI). It can be used for the transfer of chemicals, foodstuffs, fuels, oils, paints, solvents, adhesives, dyes, and detergents under very low pressure conditions. Ends can be fitted with crimped stainless steel tube sleeves. The relationship between working pressure and temperature for the HYPERLINE FX Teflon hose without a braid applies only up to a temperature of 150°C. Above this temperature, there is a decrease in working pressure and vacuum. If the hose is to be used above these temperatures, this must be taken into account, and appropriate tests should be conducted under operating conditions. Available versions: standard and antistatic. Hose material: PTFE (Teflon). Operating temperature: from -70°C to +150°C (up to +260°C – working pressure of the hose dependent on temperature).
