Tying the Tube Knot – Snelling a Tuna Circle Hook with 80lb Monofilament Line Video

Video description: How to snell a fish hook using a Tube or Nail knot. In this case, we are tying 80lb monofilament to a Tuna Circle hook. This knot is very strong and easy to tie. I used a short 110mm section of an old broken fishing rod for the tube. The Tube knot can be used for very light lines when making bait rigs all the way up to 200lb mono for heavy groper rigs to fish in very deep water.
1. Begin by passing the tag end of your mo9nofilament through the eye of the hook from the barb side. Allow a good 250 to 300mm for the knot. There is no need to cut the other end of the line from the spool at this stage. Then lay your tube along the hook shank. Make about 9 wraps from the bend towards the hook eye going around the tube and the hook shank. Then push the tag end through the tube. The line, in this case, is a heavy 200lb monofilament.

The tube knot is by far the best method of attaching deep-sea tuna circle hooks to heavy monofilament droppers. This knot retains almost total line strength. Alternative methods are to use crimps or to simply push a dropper loop through the eye and over the hook.

Note the side of the hook eye from which the monofilament exits when tying the tube knot. This is very important! The mono should always come out of the hook eye on the same side as the hook point. This continues the circle and improves your hook-up rate considerably. I have actually seen “name brand” pre-tied rigs where the line has been passed through the eye of the hook from the wrong side.

The tube knot can be tied successfully with very heavy monofilament – in excess of 200kg. The reason for heavy monofilament is to gain a measure of protection against the rasp-like mouths of deep-sea species like groper. There is nothing worse than winding up from a great depth only to find your hooks bitten­ off or that your knots holding them have come undone!

2. Slide the tube out toward the hook bend. Wet the knot with saliva before sliding the knot up against the eye before tightening. Finally, pull up tight with pliers.

To tie the tube knot well, particularly in heavy monofilament, requires a bit of practice. The secret is to wind the mono around the hook shank under the correct tension. This requires practice. Too tight and it is hard to remove the tube, on the other hand too loose and the knot will tend to fall apart in your hand.

For the tube, I have found a 100mm tip section from an old flyrod to be just ideal. This also has a slight taper making it easier to slide out.

Always moisten your knot before pulling up tight. You’ll also find when using heavy mono that you’ll need to pull both ends of the line with pliers in order to get the completed knot tight and snug looking.

3. Snip off excess mono. Finally, note the side from which the monofilament exits the eye of the hook. This is very important if the hook is to “set” automatically.

After a bit of practice, you will find this knot easy to tie. Though it can be a bit tricky, to begin with. It works equally well with lighter monofilament.

The tube knot is also ideal for tying a second fixed hook (instead of a slider) in place higher up the dropper. This rig is often used by snapper fishermen.

With lighter lines don’t pull too hard with pliers or you will damage the knot.
