PTFE Tubing

CB-TT (L/T/S)

Non-Shrink Tubing for Electronic Applications

Our tubing made from PTFE material, exhibits high temperature resistance (260°C), corrosion resistance, high insulation, and high strength. Our tubing of models CB-TT-L (150V), CB-TT-T (300V), and CB-TT-S (600V) have passed UL certification (Certification No.: E180918) and are compatible with the UL 1446 insulation system (PD GE ORGE CO/RIPLEY RESIN DASH2B-5 system).

Material: PTFE (Polytetrafluoroethylene)
