Designed specifically for pleasure boats, hose REF 817 has a butyl rubber inner tube which has the best impermeability to gasses in the range of elastomers.
Consequently, it is destined to connect effluent circuits on yachts.
With its smooth finish, it has an excellent bend radius allowing different types of mounting inside confined cockpits.
Its white colour allows easy incorporation into sanitary environments.

Hose REF 831 is intended for discharging food products such as suger, powdered milk and flour. it is also used for discharging pvc granulates. in 5mm thickness, it can be rolled flat.
In 7mm thickness, its life span is increased by using a 5mm thick inner tube and through its “round-shape memory” which avoids kinking.
It can be equipped with swaged guillemin end-fittings using aluminium or stainless steel ferrules.

Technical specifications:

Inner tube : white anti-abrasive food quality NR rubber
Reinforcement : 2 textile plies
Outer cover : abrasion and weather resistant CR rubber
Electrical conductivity : copper braid inserted between textile plies
Outer finish : wrapped
Temperature : - 30°C to +60°C
Production lengths : 20 metres
Colour : blue or black
