Typical Applications

The extra flexibility and low shrink

temperature of SFTW-203 tubing make it

ideal for shrink-fit jacketing and

insulation of flexible wire bundles and

temperature sensitive components. T h e

3:1 shrink ratio makes SFTW-203 the

insulation of choice for end terminations

where the connector body is larger than

the cable and for repair applications

where the tubing must be slid over a

c o n n e c t o r. SFTW-203 can also be used

to insulate an oversized component in

line to the wiring.

Shrink Ratio

S F T W-203 has a 3:1 shrink ratio. W h e n

freely recovered, the tubing will shrink to

33% of its as-supplied internal diameter.

The recovered wall thickness of the

tubing is proportional to the degree of

r e c o v e r y.

Ordering Information

Order SFTW-203 by product name, size

equivalent to expanded inner diameter,

c o l o r, and package type. Always order

the largest size that will shrink-fit snugly

over the item to be covered.
