Isotta Float Tube 70mm Diameter - Length 80mm



The Isotta 70 mm diameter, 80 mm long float tube for Isotta 25 mm double ball float arms are built entirely in anodised aluminium. The floating tube system allows you to expand on the Isotta 25 mm diameter double ball float arms. This will add buoyancy to your system and allow you to change the buoyancy with interchangeable float tubes. The fastening system closes the sealed chamber and fixes the position on the float tube allowing flexible buoyancy control in water.

Technical Data

  • Anodised anticorodal aluminium
  • O-ring on the fixing screw for proper sealing
  • Ergonomic seal screw for underwater use
