Pressure Resistance for Flexible Connectors
Flexible Length up to 300mm
0,34 Bar / 5.0 PSI For temperatures up to 90 °C / 195°F
-0,2 Bar / -2.9 PSI For temperatures up to 90 °C / 195°F
These pressures may cause expanded or contracted shapes.
Filcoflex can additionally add reinforcement rings to reduce contraction or expansion of the cylindrical shape.
Please contact us for more information for higher pressures, higher vacuum, or longer lengths.
Weighing Applications
Very suitable for high volume weight and capacity weighing and dosing applications where the required accuracy is >1kg. If the required accuracy is <1KG, please contact Filcoflex and explore Weighing Flexible Connections like silicone bellows, poly urethane bellows, PU-UF03 sleeves or PTFE 310 fabric.
Chemical Resistance

ATEX & Explosion Safety
PU-UF3 has been tested for its electrostatic properties, and has been found ATEX compliant and safe to use in all dust explosion hazardous areas, such as ATEX zones 20, 21, 22.*
Surface Resistance: 5 x 1012 Ω IEC 60093/EN1149 and TRGS 727
Volume Resistance: 3 x 1011 Ω IEC 60093/EN1149-1 and TRGS 727
No propagating brush discharges could be determined.
Non Conductive but safe to use up to a length of 1000mm.*
PU-UF3 has also been explosion pressure tested and found safe to up to an explosion pressure of 1,5 Bar up to a length of 300mm.
Availability for shapes, couplings and product features
PU-UF3 can be custom made in to almost any flexible sleeve and many other products. This document summarizes all the different shapes, end couplings and product features that are available for this flexible material.
