PTFE Heat Shrink Tubing 4:1 • Fractional

PTFE Heat Shrink Tubing 4:1 is a high temperature Fluoropolymer that has the highest shrink ratio available among the Fluoropolymer’s. Heat Shrink PTFE Tubing offers the ultimate performance with the highest continuous working temperature. 4:1 Heat Shrink PTFE is designed for applications where hose or pipe fittngs can not be removed in order to apply the Teflon sleeve. Being able to slip the tubing over odd shaped fittings and nuts allow for quick install of a protective PTFE sleeve over machine parts with out having to break down an entire system. In addition to the many chemical and corrisive properties found in PTFE, the Thin Wall of Heat Shrink PTFE 4:1 promotes quick installation while keeping the covered tubing flexible.

PTFE Shrink Tubing’s applications include insulating, terminating, moisture sealing, splicing, and wire bundling. Colored Heat Shrink Ptfe tubing can also be a great visual for coding wires. See the Data Sheet for a summary of Heat Shrinkable PTFE Tubing & its properties.
