Manufactured using 100% polyurethane sheeting, they are highly stable in the presence of oil, grease and aliphatic hydrocarbons (petrol). However, aromatic hydrocarbons and chlorine can occasionally produce slight swelling. They are insoluble in alcohol, water and ether, but less resistant to hot water and steam.


Antistatic: With a copper wire parallel to the wire spiral for better electrostatic discharge.

Food grade: With special food-grade polyurethane for transporting foodstuffs.


Suitable for suction of all types of abrasive particles such as sawdust, chips, granular products, salt, sugar and powder of all types including cement.

Ideal for all kinds of machinery for the wood industry.

The hoses can be ordered with wire fitted parallel to the spiral wire, to improve static electricity discharge.

These hoses can also be used for foodstuff transporting, but this should be indicated when ordering so that the grade suitable for foodstuffs can be supplied.


This tube is made of 2 overlapping sheets of polyurethane, half of one sheet overlapping half of the other and welded together, with copper or brass-platted steel wire sandwiched between both sheets.


From -18ºC to +80ºC (up to 100ºC for short periods of time)

From -0,4ºF to +176ºF (up to 212ºF for short periods of time)


These hoses are manufactured in the following inner diameters: 50mm to 500mm. (1,97’’ to 19,68’’)

Minimum length: 5m (16,4ft)

Maximum length: 30m (98,43ft)

If IDs are between 50 and 200mm (1,97’’ and 7,87’’) the hoses are supplied in a polyester net in order to reduce the shipment fee. Any diameter longer than 200mm (7,87’’) will be supplied in paper boxes.
