Decoy T-2 Urethane Tube

Protect your fishing leader from abrasion and line damage with the Decoy T-2 Urethane Tube, a flexible protective sleeve designed for heavy-duty fishing rigs, crimped leaders and big game fishing applications.

The Decoy T-2 Urethane Tube is a practical rigging accessory designed to protect fishing leaders at high-stress connection points. Made from flexible urethane material, this transparent protective tubing helps reduce abrasion and wear where fishing line comes into contact with metal components, knots, crimps and other parts of a fishing rig.

Ideal for GT fishing, heavy jigging and light tackle game fishing, the Decoy T-2 can be fitted over sections of leader to provide additional protection when targeting powerful species such as giant trevally, kingfish, amberjack and dogtooth tuna. Available in multiple internal diameters to accommodate different leader sizes, each pack contains 1 metre of tubing that can be cut to the required length for custom rigging applications.

Key Benefits

• Protective Urethane Construction – Flexible tubing helps protect fishing leaders against abrasion and wear at high-stress connection points.
• Reduces Line Damage – Provides a protective barrier between the leader and metal components, helping minimise friction and potential line damage.
• Ideal for Crimped Leaders – Suitable for protecting leader sections around crimps, loops and other heavy-duty rigging connections.
• Heavy-Duty Fishing Applications – Particularly useful for GT fishing, heavy jigging and light tackle game fishing.
• Flexible and Easy to Work With – Urethane material allows the tubing to follow leader loops and bends during rig assembly.
• Multiple Diameter Options – Available in four internal diameters to suit a range of leader thicknesses.
• Customisable Length – Supplied in a 1 metre length that can be trimmed to suit individual rigging requirements.
• Transparent Finish – Clear tubing provides a discreet protective sleeve without adding unnecessary colour to the rig.
• Versatile Rigging Accessory – Suitable for use with heavy monofilament and fluorocarbon leaders, provided the correct tubing diameter is selected.

Size Guide

Tube Internal Diameter	Recommended Leader Class
0.6mm	Approx. 3–8 Gou (Japanese Line Size)
0.8mm	Approx. 6–16 Gou (24–65lb)
1.0mm	Approx. 16–30 Gou

Size recommendations are based on the manufacturer's Japanese monofilament line classifications. Actual leader diameter varies between brands and materials. Check your leader's diameter before selecting a tube size.

Expert Advice

The Decoy T-2 Urethane Tube is particularly useful when building heavy-duty fishing leaders where abrasion and concentrated pressure can weaken the line. Common applications include protecting leader loops around solid rings, swivels and other terminal tackle connections.

For GT casting and heavy jigging, position a suitable length of tubing over the leader section that will contact the metal component. The manufacturer recommends approximately 10–30cm of tubing for certain leader protection applications, although the required length will depend on the rig and connection being used.

When making crimped leaders, slide the tubing onto the leader before forming the loop and securing the crimp. Position the tubing so it protects the section most likely to experience friction or abrasion. Always ensure the crimp and leader connection are correctly assembled and tested independently of the protective tubing.

Choose a tube with an internal diameter that comfortably accommodates your leader without excessive force. Because monofilament and fluorocarbon diameters can vary significantly between manufacturers, use the actual line diameter rather than breaking strain alone when selecting the correct size.

Frequently Asked Questions

What is Decoy T-2 Urethane Tube used for?

Decoy T-2 Urethane Tube is designed to protect fishing leaders from abrasion and wear, particularly around crimps, knots, loops and metal terminal tackle connections. It is commonly used for GT fishing, heavy jigging and game fishing rigs.

What size Decoy T-2 Urethane Tube should I use?

The correct size depends on the diameter of your fishing leader. Decoy offers internal diameters of 0.6mm, 0.8mm, 1.0mm and 1.5mm. Check the actual diameter of your monofilament or fluorocarbon leader and select tubing that allows the line to pass through comfortably.

How much tubing is included in each pack?

Each pack of Decoy T-2 Urethane Tube contains 1 metre of clear protective tubing. It can be cut into shorter sections to suit different leader configurations and rigging requirements.

Can Decoy T-2 Urethane Tube prevent fishing line from breaking?

The tubing helps reduce abrasion and friction at vulnerable connection points, which may reduce the risk of line damage. However, it does not increase the rated breaking strain of your leader or replace correctly tied knots, properly fitted crimps and regular rig inspections.
