Product description
3M™ Heat Shrink Tubing FP-301 offers
an outstanding balance of electrical,
physical and chemical properties
for a wide variety of industrial and
military applications. Rated for 135°C
(275°F) continuous operation, all
FP-301 tubing is split resistant,
mechanically tough, easily marked
and resists cold ow.
FP-301 tubing meets AMS-
DTL-23053/5* Class 1 & 2 requirements.
It is UL Recognized and CSA Certied at
600 volts at 125°C (257°F) (UL File
No. E-39100; CSA No. 38227).
FP-301 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 short
periods. Minimum shrink temperature for
all FP-301 tubing is 100°C (212°F).
Typical applications
FP-301 tubing is typically used as a
shrink-t electrical insulation over cable
splices and terminations. It is also used
for lightweight wire harness covering,
wire marking, wire bundling, component
packaging and re-resistant covering.
Shrink ratio
FP-301 polyolen 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-ratio FP-301 tubing
meeting AMS-DTL-23053/5* Class
1 requirements for overexpansion is
available subject to factory quotation.
Colors
Class 1 (ame retardant): black. Class
2 (non-ame retardant): clear. Also
available in Class 1: blue, green, red,
white and yellow. Price, minimum order
quantity and lead times will vary for
these, however.
Standard packaging
Four-foot lengths, large spools
(21" diameter) and small spools
(8-1/2" diameter).
Ordering information
Order FP-301 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-301 tubing, 1/4", 4 ft., white.
