What should be done if a Teflon hose has developed a permanent set due to high pressure or temperature exposure?

When a Teflon hose develops a permanent set due to high pressure or temperature exposure, it indicates that the material has been deformed beyond its elastic limit and may no longer perform reliably. This permanent set can lead to issues such as leaks, bursts, or failure to maintain the required fluid flow, which in turn can compromise the overall hydraulic or pneumatic system's integrity and safety.

It is essential to discard the hose to prevent any potential hazards and ensure that the system operates effectively. The integrity of the hose material is critical for safe operations, and attempting to reuse a permanently deformed hose could pose significant risks. Therefore, replacing it with a new hose is the best practice to avoid failures caused by compromised equipment.
