We do not currently carry the Q2-F-1/8-01-SS1000FT heat shrink tubing from Qualtek, however we can offer Q2-F-1/8-01-SS500FT from the same manufacturer. As seen on the snip from their part numbering guide the only difference between the two is the packaging and length of the spool.
We also offer this product precut to a number of different lengths, please use the link below to see all of the length options we offer for this product.
