Tenara Lifetime Guaranteed Thread features unique PTFE (polytetrafluoroethylene) fiber construction that extends the life of fabric seams and ultimately the products in which it is used. GORE® Tenara has high strength and durability that for over 10 years has proven to be unaffected by exposure to UV rays, cleaning agents, pollution, saltwater, air, rain and snow.
Great for outdoor, awning and marine applications, Tenara thread will not rot if left outside all year round. It remains colorfast even in extreme temperatures and frost. Although more expensive, Tenara is a greater value than other polyester threads when considering life span and re-stitching costs. Choose Tenara thread to improve the performance of outdoor fabrics where seam life and integrity are of the utmost importance.
Tenara M1000H is similar in weight to V-138. Heavy Tenara thread requires a needle size of #19 or #20. Smaller needles may cause skipped stitches and/or the double ply thread to unravel above the eye of the needle. Tenara thread does not require as much upper tension as normal polyester thread. Heavy Tenara thread usually requires less tensioning which will result in a good-looking stitch on both the top side of the fabric and bottom, but the knot on the bottom side usually does not pull up into the fabric all the way.
We recommend using Tenara thread with rotary hook sewing machines like the Sailrite® Fabricator®, 111, Professional and Big-N-Tall. Not sure if your machine has a rotary hook? Learn more in our Rotary vs. Oscillating Hook Sewing Machines article.

Tenara works well on Sailrite 111
Was pleasantly surprised at the performance of this product while stitching our trimaran nets on the Sailrite 111. Minimal skipped stitches on the very heavy nets and hardly any when sewing other materials. Thanks to Sailrite for the guidance videos for providing tips on machine adjustments for this different kind of thread.
Great thread for my genoa and Lazy bag
Thread is good
Great product! I used it previously 10 years ago on my marine cushions and they are still going strong!
The best Thread i used
Finally a PTFE thread I can fly with
This is the BEST thread I have ever used for marine canvas. My industrial Pfaff loves it and I can sew as fast as I dare. The 92 size would break if I barely went over idle. I only use this thread now.
Tenera thread use
The thread quality is excellent. The problem is to adjust the sewing machine. The thread is very slippery. The result is very nice but hard to work with.
