Sigal EXTREME rubber, features a tiny internal bore hole and available in a range of outer diameters: 13mm, 14.5mm, 16mm, 17.5mm or 19mm. The SIGAL EXTREME are black rubbers with a very thin coextrusion in a deep purple color. Price is per 10cm.

We will cut a continuous length so you get exactly the amount of rubber you need! Need less than a metre - just order the part metres (in 10 cm increments) as required!

The uniqueness of these rubber is the reduced size of the central hole for the housing of the wishbones: while in the traditional rubber the width of the central hole is 3mm, the width of EXTREME is of only 1mm! This feature increases the power applied, considering that the amount of rubber present in the given space is 2mm more. It also provides better speargun maneuverability due to the low profile to power ratio eg. 14mm bands have equivalent power to 16mm. Small internal hole still allows all conventional bridles to be inserted, with lubrication.

This rubber has been tested with an elongation factor of 360% but is able to withstand higher stretch factors if more power is required.

• Choose from a variety of outer diameters
  
• Deep purple over black
• Tiny 1mm internal bore
