PTFE Internal Bush – Internal Bush for Pole Tip

The Cresta PTFE Internal Bush provides a smooth internal exit for the top elastic in your pole or top kit. The bush is fitted into the end of the pole tip and reduces the opening to a suitable diameter. This allows you to use finer elastics without having to shorten different tips to uneven lengths.

The lightweight PTFE has a very smooth surface, allowing the elastic to move freely and reducing abrasion against the carbon. This helps extend the life of the elastic and ensures smooth performance during the fight. Especially when several match tips need to remain exactly the same length, this bore-reduction system offers a neat and consistent solution.

Key features

• Internal PTFE bush for poles and top kits
• Reduces the pole tip opening for finer elastic
• Smooth surface limits friction and wear
• Lightweight finish for a neat tip setup
• Helps keep different top kits at the same length

Combine the internal bush with suitable Cresta Hollow Elastic for a complete elastic setup.

How do I choose the right internal tip bush?

Match the outer diameter of the bush to the inner diameter of the shortened pole tip. Also check that the opening is wide enough to allow the chosen elastic to move freely without pinching.

When is a bore-reduction system useful?

This system is particularly useful when the existing tip opening is too large for a thinner elastic. You reduce the passage with the bush without having to shorten the tip further.
