Product description
3M™ Heat Shrink Tubing FP-301VW has
the same outstanding balance of electrical,
physical and chemical properties as
FP-301 tubing and is specially engineered
for excellent ame resistance.
FP-301VW tubing meets AMS-
DTL-23053/5*, Class 3 requirements. It is
UL Recognized and CSA Certied at
600 volts at 125°C (UL File Nos. E-39100
and VW-1; CSA No. 38227, OFT).
FP-301VW tubing is rated for
continuous operation from –55°C (–67°F)
to 135°C (275°F) and withstands elevated
temperatures to 300°C (572°F) for brief
periods. Minimum shrink temperature for
all FP-301VW tubing is 100°C (212°F).
Typical applications
FP-301VW tubing is ideal for re-
resistant coverings of components
and ammable wire assemblies.
Shrink ratio
FP-301VW tubing has a 2:1 shrink ratio.
When freely recovered, the tubing will
shrink to 50% of its as-supplied internal
diameter. The recovered wall thickness
of the tubing is proportional to the degree
of recovery. High expansion ratios are
available subject to factory quotation.
Colors
Standard color is black. Also available in
blue, clear, green, red, white and yellow.
Price, minimum order quantity and lead
time will vary for these, however.
Standard packaging
Four-foot lengths or large spools.
Cut pieces available subject to
factory quotation.
Ordering information
Order FP-301VW tubing by product
name, size equivalent to expanded inside
diameter, package type and color.
Always order the largest size that will
shrink snugly over the item to be covered.
Example: FP-301VW tubing, 1/4",
4 ft., white.
