Different formulations and brands of plumber’s tape will typically have different temperature ratings, but the majority cover a fairly wide range of operating conditions.

The minimum safe operating temperature for PTFE tapes is around -200 Celsius, while the upper limits of heat performance tend to be at around +260 Celsius. PTFE itself has a high melting/decomposition point (of around +327 Celsius), but it begins to deteriorate as temperatures rise through the +200 to +260 Celsius range.19mm PTFE Tape Manfuacturers

 

 

Not all thread seal tapes will be able to withstand this full array of safe operating temperatures - plumber’s tapes intended for use in high-temperature applications will be marked as such. Always check the specified heat rating in the product information provided by the supplier and manufacturer.
