Heat Shrink Tubing

ptfe/ FEP dual wall heat shrink sleeving

PTFE/ FEP dual wall heat shrink consists of a heat shrinkable PTFE sleeving with an inner FEP wall.


The unique properties of the dual wall heat shrink sleeving lends its utilisation in any application that requires a high working temperature, non-stick surface, high electrical resistance and chemical resistance.

With PTFE/ FEP dual wall heat shrink, it is possible to ‘pot’ components in pure fluoroplastic and protect them against mechanical and chemical exposure, even in immersed conditions.

PTFE/ FEP dual wall heat shrink sleeving is available in standard sizes, from 0.9mm to 11mm ID. Find our PTFE/ FEP Dual Wall Heat Shrink Sleeving Sizes.
