 Style E (After Shrinking) |
- 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.
