If you're looking for speargun rubber that will stretch to %400, hold energy in a loaded state for a long duration with minimal power loss, and have a continuous smooth release instead of a burst that results in muzzle kick and reduced speargun accuracy, then this is the rubber tubing for you.

 

                                                                             Understanding rubber tubing specifications
Measuring rubber tubing
For conventional 5/8" (16mm) speargun bands add 1/4" left wall thickness + 1/8" ID/hole + 1/4" right wall thickness for a total of 5/8" OD. The specification for typical 5/8" speargun bands is 1/8 X 1/4 (ID X Wall).

In comparison Speardiver small hole rubber tubing ID is reduced by half (1/16") and the wall is increased by 1/32". The tubing has a smaller hole and maintains 5/8" OD. The specification for Speardiver small hole 5/8" rubber tubing is 1/16 X 9/32. The same formula applies to all Speardiver small hole rubber tubing: 14mm, 16mm, 17.5mm and 19mm.

Why the format of this rubber tubing was chosen

  • Quality speargun rubber tubing is made of Latex/natural rubber, which comes from the sap of the rubber tree. Latex in its natural color Amber is less resistant to sunlight. An outer layer of black dyed Latex adds UV protection and extends the life and performance of the band.
  • Cut open a band open after a day of spearfishing and you'll see water come out of the hole. The cycles of stretching and compression draw water into the band no matter how well you tie the wishbone, and it remains trapped there. Salt water damages the band from the inside, you can see this layer of deteriorated rubber immediately around the hole of a used band. The small 1/16" hole significantly lessens water intrusion into the band, improving performance and increasing longevity.
  • Less hole equals more rubber at the same diameter, which equals more power without increasing the profile of your speargun.
