Flexible hose made of PVC-coated polyester fabric on the outside and aluminized fiberglass fabric on the inside.

Easy assembly thanks to the reinforced ends (approximately double the thickness of the rest of the hose) without metal spirals which allow the hose to be secured using hose clamps easily found on the market.

Tube supplied complete with suspension rings or rings at the ends for fixing to the ground or wall.
Chemically resistant metal spiral because the fluid conveyed is outside the hose and does not alter its characteristics. The interior of the hose is virtually smooth, with minimal pressure drops. High tensile strength. The internal aluminum foil makes it exceptionally resistant to sparks.
