  • NOTEThis is a full spool of Ultra TNT Seam Seal Tape (53 yds). Are you looking for smaller amounts? Click HERE for sales by the yard.

    UltraTNT™ PSA Tape is a waterproof seam repair tape with Ultra™ fiber. Constructed with two laters of 0.25 mil polyester film with light grey Ultra™ yarn inserted in the warp and bias. The backing is a pressure sensitive, high-tack, non-yellowing adhesive.

    Designed to be applied to the film side of fabrics to reinforce and waterproof seams. The tape is very stretch-resistant along the length of the roll, where there are straight parallel Ultra™ yarns inserted to control stretch. The Ultra CrossPly™ yarn helps control bias stretch and adds to the tear-resistance of the tape.

    Compared to stitching alone, using a quality seam sealing tape makes your finished product   stronger  (i.e. it lasts longer) and also more   waterproof.

    For some laminated fabrics, it's a   must-have  to prevent issues like stitch elongation.


    - 2 layers of .25 mil Polyester film

    - Light grey Ultra™ yarn inserted in the warp and bias

    - Pressure Sensitive adhesive backing

    Note  - This seam seal tape will work with all of our tapeable fabrics ( X series X-pac,   ECOPAK EPLX,   Challenge Ultra,   Dyneema Composite Fabric,   Venom, etc).

PSA tape

Easy to use. Sticks well to the Challger line of fabric as well as, vx, dyneema. I used to order small lots but went with the full roll to avoid downtime. Great product.

Thanks for the review. This ULTRA TNT PSA Tape is a wonderful project great for taping seams. Ordering full rolls is definitely the way to go! Thanks again :)
