Can VISIFLON TO braidless Teflon hose be used above 100Â°C, and how does temperature affect its working pressure and vacuum performance?

Can VISIFLON TO braidless Teflon hose be used above 100Â°C, and how does temperature affect its working pressure and vacuum performance? Yes . VISIFLON TO braidless Teflon hose can be used above 100Â°C (continuous operating range is â70Â°C to +100Â°C, with capability up to +230Â°C), but its rated working pressure applies only up to 100Â°C and vacuum rating only up to 80Â°C. Above these temperatures both working pressure and vacuum performance decrease. Typical working pressures at or below 100Â°C range from 2 to 4 bar depending on hose diameter; above 100Â°C expect reduced pressure capacity and diminished vacuum holding. If you plan operation above 100Â°C (or vacuum above 80Â°C), you must account for the reduced performance and perform appropriate tests under actual operating conditions to verify safety and suitability.

Is the VISIFLON TO braidless Teflon hose suitable for transferring food or pharmaceuticals requiring FDA-compliant materials?

Yes. The VISIFLON TO braidless Teflon hose is suitable for transferring food and pharmaceuticals requiring FDA-compliant materials: the standard (natural, translucent) VISIFLON TO meets FDA 21 CFR 177.1550 and the antistatic VISIFLON TO AS (carbon-infused) meets FDA 21 CFR 178.3297. It is made of high-quality spiral corrugated PTFE, allows visual flow control, is flame-retardant, and is rated for operation â70Â°C to +100Â°C (service up to +230Â°C with reduced pressure capability). Note working-pressure limits (2â4 bar depending on diameter) apply up to 100Â°C (vacuum performance up to 80Â°C); for use above these temps perform application-specific testing and consider pressure/vacuum reductions.

How should I install fittings on the VISIFLON TO braidless Teflon hose to ensure proper sealing and performance?

To ensure proper sealing and performance when installing fittings on the VISIFLON TO braidless Teflon hose, follow these steps: 1. Prepare the hose tail - Use special equipment to straighten the spiral corrugations along the length of the fitting tail. Straightening is essential to create a smooth contact surface for the ferrule and to avoid leaks. 2. Choose compatible fittings and ferrules - Use fittings and stainless-steel ferrules designed for unbraided PTFE hoses. Materials and dimensions must match the hose inner/outer diameters and intended pressure range (2â4 bar depending on diameter). 3. Assembly method - Slide the stainless-steel ferrule over the straightened hose tail. - Insert the fitting insert fully into the hose, ensuring correct engagement depth and alignment. - Crimp the ferrule firmly with an appropriate crimping tool calibrated for the ferrule type and hose size. Proper crimping compresses the ferrule evenly onto the straightened corrugations to create a reliable seal. 4. Temperature and pressure considerations - Verify working pressure only up to 100Â°C (vacuum ratings up to 80Â°C). Above these temperatures the allowable pressure and vacuum decrease; if service will exceed these limits, perform tests under actual operating conditions and select fittings rated for higher temperatures if needed. 5. Antistatic option - For applications with static-risk fluids or environments, use VISIFLON TO AS (carbon-infused) and matching antistatic-capable fittings to ensure charge dissipation. 6. Final checks - Inspect crimped joints for uniform compression and absence of gaps. - Pressure-test the assembly at operating conditions before putting into service. - Confirm compliance with relevant standards (e.g., FDA where required). Following these steps ensures secure, leak-free fittings and reliable performance of the VISIFLON TO braidless Teflon hose.

The unbraided version TO (Tube Only) of the VISIFLON hose, made of high-quality spiral corrugated PTFE (right-handed), provides exceptional flexibility, elasticity, and vibration resistance among Teflon hoses. The VISIFLON TO hose can be used for the transfer of chemicals, foodstuffs, fuels, oils, paints, solvents, adhesives, dyes, and detergents under very low pressure conditions. The standard version of VISIFLON TO is made of natural, translucent PTFE, allowing for visual flow control. The antistatic version VISIFLON TO AS made of carbon-infused 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 VISIFLON TO, 21 CFR 178.3297 for VISIFLON TO AS). It is flame-retardant (UL94 V-0) and has a high oxygen index (LOI). Hose assembly requires straightening the corrugations along the length of the tail of the fitting, performed on special equipment. The fittings can then be installed by crimping with stainless steel ferrules. The working pressure value for the unbraided VISIFLON Teflon hose applies only up to a temperature of 100°C, and in the case of vacuum, up to a temperature of 80°C. Above these temperatures, 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. Hose material: spiral corrugated PTFE (Teflon). Operating temperature: from -70°C to +100°C (up to +230°C). Working pressure: from 2 bar to 4 bar – depending on the hose diameter.
