Teflon compression-type fitting
Housing from stainless steel, compression cone from Teflon
The compression cones used are made from Teflon. This offers the advantage that the sheathing thermocouple can be quickly replaced with another or the installation length can be modified several times. It is nevertheless recommended that a new compression cone be used each time. The disadvantage is Teflon’s limited temperature resistance of 200 °C maximum.
