Also known as breakout boots, these splitters insulate and seal the point where wire splits off from cable. An adhesive lining melts when the splitter is heated and bonds to the underlying surface, creating a water-resistant seal.
Splitters for round cable are often used with armored cable, sheathed cable, and conduit ends.

- Material: Polyolefin Plastic
- Shrink Ratio: See Table
- Dielectric Strength: 200 V/mil
- Shrink Temperature: 250° F
- Temperature Range: -65° to 275° F
A different shrink ratio on each end allows this tubing to fit over cable assemblies and wire harnesses with large connections, or around connectors with a 90° elbow. An adhesive lining melts when the tubing is heated and bonds to the underlying surface, creating a water-resistant seal. The tubing length listed is after shrinking; the length before shrinking is 20-25% shorter.
Lipped tubing has a ridge on the inside of one opening for better retention than non-lipped tubing. It’s often used with grooved adapters—upon shrinking, the lip grips onto the groove.
Dielectric strength is the maximum voltage a material can handle before it starts to breakdown.
