Our NanoTight Tubing Sleeve is specifically cut to a precise 1.6″ length. Our sleeves are carefully manufactured using FEP fluoropolymer -€“ a highly inert, melt-processed polymer that serves as an excellent alternative to PTFE. These sleeves are available in a light tinted color that allows easy identification of the ID. They are primarily used with NanoTight Fittings and work well with Super Flangeless Fittings. It comes in orange and natural color. Brochure
