Note: These ratings are for flexible couplings or expansion joints in the fully extended condition. When they are at the neutral length or compressed, it is sometimes possible to exceed the listed temperature at full vacuum; consult the Tampa Rubber Customer Service Department

PTFE expansion joint 3 convolutes  DN25 - DN500
High levels of flexibility require ongoing adjustments.
Fine-tuning to meet requirements from industry and the newest technology.
PTFE expansion joints are particularly suitable for aggressive media. PTFE is virtually non-combustible and resistant to almost all chemicals and solvents.
PTFE expansion joints are commonly used in machine units, machines, industrial equipment and piping systems.
