OPST Junction Tubing is specialist silicone tubing designed for rigging intruder flies, articulated patterns, and tube flies with trailing hooks. Each pack contains 50cm of premium silicone tubing — enough for multiple flies depending on your rigging style and hook sizes. Available in Black and White, and currently at clearance pricing whilst stocks last.
Why Use Junction Tubing?
Junction tubing creates a flexible, hinged connection between the fly body and the trailing hook. This articulated design allows the hook to move independently from the fly, reducing the leverage fish can use to throw the hook during the fight — significantly improving landing rates when fishing for powerful species such as Atlantic salmon, sea trout, and pike. The tubing also protects the fly body from damage during aggressive takes.

What Flies Use Junction Tubing?
- Intruder patterns for Atlantic salmon on Scandinavian and Scottish rivers
- Articulated streamers for pike and large trout across European freshwaters
- Tube flies with trailing hooks for Baltic sea trout and salmon

Colour Guide
Black tubing blends with dark fly patterns and is less visible in low-light or coloured water conditions. White tubing suits lighter-coloured flies and can add a subtle visual point of interest. Many tyers keep both colours to match their full range of patterns.
Frequently Asked Questions
What is OPST Junction Tubing?
OPST Junction Tubing is specialist silicone tubing used in fly tying to create a flexible, hinged connection between the body of an intruder or articulated fly and its trailing hook. Each pack contains 50cm of tubing in either Black or White.
Why do intruder flies need junction tubing?
Junction tubing creates a hinged connection that allows the trailing hook to move independently from the fly body. This reduces the leverage fish can use to throw the hook during the fight, significantly improving landing rates — particularly important when targeting powerful species such as Atlantic salmon, sea trout, and pike in strong currents.
How do you rig junction tubing on a fly?
The tubing slides over the eye of the trailing hook and secures it to the shank or tube of the fly body. This creates a hinged connection that allows natural movement in the current whilst keeping the hook firmly attached. When a fish is hooked, the fly body can slide up the leader, reducing the risk of the hook pulling free.
What flies can I use junction tubing on?
Junction tubing is used on intruder patterns, articulated streamers, tube flies with trailing hooks, and any large fly pattern that requires a hinged hook connection. It is particularly well suited to Atlantic salmon flies, sea trout patterns, pike streamers, and modern Spey flies tied for European rivers and coastlines.
Which colour junction tubing should I choose?
Black tubing blends with dark patterns and is less visible in low-light or peaty water conditions. White tubing suits lighter flies and can add a subtle visual element to the pattern. Many tyers stock both colours to cover their full range of patterns.
How much tubing is in a pack?
Each pack contains 50cm of premium silicone junction tubing — enough for multiple flies depending on your rigging style and the hook sizes you are using.
Is OPST Junction Tubing available in Europe?
Yes — OPST Junction Tubing is available from Balticflyfisher with shipping across Europe. It is currently available at clearance pricing — an excellent opportunity to stock up on a fundamental fly tying component at reduced cost whilst stocks last.
