Rio Level T Welding Tubing
Rio Level T Welding Tubing complements the InTouch Level T sinking material and other fly line, allowing anglers and fly shops to customize the length of each sink tip by welding a loop in the end. Place this heat-shrink tubing over a doubled-back fly line to allow for an easy welded loop to be performed. Both sizes shrink to approximately 50% of their original size.

The welding process is smooth and reliable. I used the regular size for my T-11 sink tip and it held well after heating. The tubing fits perfectly and the loop stays secure during casting.

Works great for customizing sink tips. The large size fits my T-14 line exactly. I appreciate the consistent shrink rate and the ease of use when applying heat.

I’ve used this tubing in several fly setups. The heat-shrink works cleanly and the loop doesn’t loosen during fishing. It’s a small but essential tool for fly tying.
