Rio Fluoroflex Strong Tippet
Ultra-Strong, 100% Fluorocarbon With Exceptionally High Tensile Strength, And Exceptionally Easy To Tie Knots In
RIO’s newest tippet material is an ultra-strong, 100% fluorocarbon with exceptionally high tensile strength. The material is very easy to tie knots in, with high knot strength and a smooth finish that ensures knots seat easily and tightly. The high break strength to diameter ratio makes this a fantastic fluorocarbon for the trout fly fisher. RIO is proud to introduce “half sizes” of core trout diameters, giving anglers an extra choice when faced with the decision to choose between, say 4X and 5X. Our new 6.5X, 5.5X and 4.5X sizes will make those decisions easier. Each Normal spool has 30 yards of top quality material.

It features a high break strength to diameter ratio and is exceptionally easy to tie knots in, with a smooth finish that ensures tight, secure knots. The half-size options (like 4.5X, 5.5X, 6.5X) provide more precise matching to fly line diameters.
Is the tippet suitable for trout fly fishing?
Yes, the high tensile strength and smooth knot performance make it ideal for trout fly fishing, where sensitivity and knot reliability are critical.
How many yards are in each spool?
Each normal spool contains 30 yards of tippet.

Una Hodges –
I’ve used this tippet for several trout fishing trips and found it to be very strong and easy to tie. The knots hold well and don’t slip during casting. The 5.5X size matched perfectly with my fly line and gave a smooth feel in the water.
Mary Peters –
The half-size options are a game changer. I used the 4.5X with my 4X line and it made a big difference in sensitivity. The material is durable and the knots stay secure even after long days on the water.
Amelia Sutherland –
Good strength and easy to tie. The 6.5X size works well with my heavier fly line. A bit more expensive than standard tippets, but worth it for the performance and reliability.
