Heat shrinkable sleeving is intended for use as a snug-fitting electrical insulator over wire bundles, splices, cables, cable harnesses, bus bars, connectors and terminals, metal or fibrous tubing, hydraulic line couplers, high voltage tubes, flexible wave guides and rectifier leads, as extra insulation over hot spot areas, and as a cable blast shield in rocket launching. Specific property values in Section 3 and in the specification sheets should be evaluated for the particular use intended. When a complete moistureproof seal is required, the manufacturer may recommend the use of a suitable sealant at the ends of the sleeving. Heat shrinkable sleeving can be marked before shrinking and be used to identify materials that cannot be marked directly such as unjacketed wire, shielded wire, thermocouple wires, multiconductor cable, asbestos, and fiberglass. Markings shall be in accordance with procedures in MIL-M-81531. It should be noted that the wall thickness dimension in the specification sheet or manufacturer's data sheet refers to the sleeving after unrestricted shrinkage; if shrinkage is restricted by the object to be enclosed, wall thickness will be less. The particular uses for heat shrinkable sleeving are dependent upon the specific properties described by the individual specification sheets. General end use applications follow:

/1: Intended for use on heavy duty cables or harness systems such as ground support.

/2 and/3: Inactive for new design. Shall not be used in any application when outgassing is a problem.

/4: For one step potting, encapsulation, or moisture sealing and corrosion protection of electrical components or terminations.

/5: Used for light duty harness jackets, wire color coding, marking, or identification.

/6: Used for wire identification, marking, or strain relief.

/7: Used for light duty wire identification and component covering.

/8: Used for wire or termination strain relief at elevated temperatures.

/9: Cancelled.

/10: Used for high or low temperature applications or where ablation resistance in high blast flame is required.

/11: Used where strain relief is necessary at high temperatures.

/12: Used at high temperatures where resistance to flame is important to protect high temperature cable, components, and terminations.

/13: Used in elevated temperature applications or where exposure to elevated temperature solvents is expected.

/14: Used as component and electronic lead strain relief where low expansion ratios are satisfactory. Operates over fairly wide temperature range.

/15: Used for repair of heavy duty cables, splice covers.

/16: Used on heavy duty cables and harness systems, which see high levels of physical abuse, and requires resistance to fuels and oils coupled with high and low temperature extremes.

/17: Used for see through wire identification where flame resistant properties are required.

/18: Used as wire markers, insulation, and wire and component relief. Clear material may be considered for use as replacements for non flame retarded clear sleevings.
