Flexible PTFE Teflon Pipe Tubing
We manufacture and supply PTFE Tubing and Sleeves from qualitative raw material in cost effective manner so that we can deliver these
tubing in quality standard at reasonable price. PTFE tubing is flexible tubing that is resistant to crimping and blockage. This is the preferred
teflon tubing below 270 oC
Advantages of Tubing:
• Wider Temperature Range: PTFE extruded tubings will work up to 260 oC and shall withstand a peak of 300oC for short durations.
On the lower extreme, PTFE is well known for flexibility even at cryogenic temperatures, say -200 oC
• Superior Electrical Performance: PTFE tubings electrical performance is excellent. The tube posses high degree of concentricity,
a critical parameter in all insulating requirements
• Burst Pressure: Many applications, such as chemical, hydraulic and similar areas, require the tubing to withstand certain minimum
burst pressure. For this reason one can use tubes with lower wall thickness, thus saving on cost. Tubings with SS overbraid are
also available for additional protection
• Abrasion Resistance and Flex: life of PTFE Tubings due to enhance reliability, one can work with lower wall thickness to effect
savings
• Smooth Internals: tubings are perfectly smooth and allow easy insertion of members, especially considering low coefficient of
friction advantage of PTFE
