2:1 Viton - Flexible Heatshrink Tubing
Shrinks To 1/2 its original diameter!
2:1 Viton is a rubber-like, highly fluid resistant, flame
retardant flouro-elastomer heatshrink tubing with
high solvent resistance.
The product is recommended for applications where
resistance to aggressive solvents and high tempera-
tures is required. Bundling, harnessing and environ-
mental protection within engine compartments is one
such application.

Measure the Shrinkflex® tubing to length
and cut with a scissor. The thickness of
your bundle, as well as the desired final
appearance, will determine the length of the tubing you
cut. Generally, a piece 1 1/2” - 2” long will accommodate
almost any need. Single wires, or smaller bundles, require
shorter pieces.
Slip the Shrinkflex® tubing over the
bundle and position it so that both the
sleeved and unsleeved portions are suf-
ficiently covered. Notice the small pieces of tubing in-
stalled on single wires as part of a color coding system. If
your project requires multiple operations, always work up
from the smallest to the largest bundle.
Gently apply heat to Shrinkflex® tubing
from a heat gun, hair dryer or torch with
an appropriate attachment. Keep the
heat source far enough away so that hot metal or direct
flame does not come in contact with the tubing, wires or
sleeving. Move the heat around the bundle to prevent
damaging the sleeving and to ensure that all areas of the
tubing have been shrunk. Once cooled, your installation
is complete.
