Spearit Shrink Rings

Shrink rings are a professional finishing touch to your home crafted speargun bands. They are used to cover the constrictor cord after tying and can be shrunk to a tight fit with a heat gun.

Our shrink rings are lined with a heat activated adhesive to keep them securely in place.
