Product Description 3M™ FP-301 Tubing offers an outstanding balance of electrical, physical and chemical properties for a wide variety of industrial and military applications. Rated for 135°C continuous operation, all FP-301 Tubing is split resistant, mechanically tough, easily marked and resists cold flow. FP-301 Tubing meets MIL-DTL-23053/5 Class 1 & 2 and AMS-3636, AMS-3637 requirements. It is ULRecognized and
CSACertified at 600 volts @ 125°C (UL File Nos. E-39100 and E-69751; CSANo. 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-fit electrical insulation over cable splices and terminations. It is also used for lightweight wire harness covering, wire marking, wire bundling, component packaging and fire-resistant covering.
Shrink Ration
FP-301 polyolefin 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 MIL-DTL-23053/5 Class 1 requirements for overexpansion is available subject to factory quotation.
Standard Colors
FP-301, Class 1 (flame retardant)–black, white, red, blue, green (1/16 "-1" green only) and yellow. FP-301, Class 2 (nonflame retardant)–clear. Other colors available subject to factory quotation.
Standard Packaging
Four-foot lengths, large spools (21" diameter) and small spools (8-1/2" diameter).
Ordering Information
Order FP-301 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, 1/4", 4 ft., white.
