Composite hose made from polyester fabrics and films with an aromatic barrier layer, reinforced with internal and external wire helixes.

Principal Applications

Bituflex is suitable for the transfer of bitumen and tar at elevated temperatures, primarily for wand/hand bar applications.

Safety Note

Bitumen is generally handled at elevated temperatures. Medical specialists advise that burns from bitumen usually affect the full thickness of skin, generally requiring a skin graft. Use of suitable personal protective equipment is strongly recommended.
