Transparent FEP Tube



FEP Tubing (Fluorinated Ethylene Propylene) is the preferred material in production of small diameter tubing of continuous lengths. While some temperature resistance is sacrificed with FEP (to 400º F), its chemical and dielectric properties are similar to those of PTFE.

However, it has several properties PTFE does not have. FEP is one of the clearest plastics available on the market and FEP tubing can be supplied in long, continuous coils. Also, it can be welded and tubes can be sealed by melting.
