2. Product Overview
The Dorman 85265 is a black heat shrink tubing, 3/16 inch in diameter and 8 feet in length. It is suitable for various electrical insulation and protection applications. The tubing is manufactured from a blend of Polyester, Polyolefin (PE), and Polyvinyl Chloride (PVC).
Key Features:
- Material: Polyester, Polyolefin (PE), Polyvinyl Chloride (PVC)
- Color: Black
- Dimensions: 3/16 inch (4.76 mm) diameter, 8 feet (2.44 m) length
- Shrink Ratio: Shrinks from 3/16" to 3/32"
- Operating Temperature: -55°C (-67°F) to 125°C (257°F)
This image displays the Dorman 85265 heat shrink tubing coiled within its clear plastic packaging. The label on the packaging indicates the model number, length (8 FT, 2.44 M), and key specifications such as shrink ratio (3/16" to 3/32") and operating temperature range (-55°C/-67°F to 125°C/257°F).
3. Setup and Preparation
Before applying the heat shrink tubing, ensure the work area is clean, dry, and well-ventilated. Gather the necessary tools:
- Heat source (a heat gun is recommended for consistent and safe results; avoid open flames)
- Wire cutters or scissors
- The wires or components to be insulated
Measure and cut the heat shrink tubing to the appropriate length, ensuring it fully covers the area requiring insulation or protection, with a slight overlap if necessary.
4. Operating Instructions (Application)
Follow these steps for proper application of the heat shrink tubing:
- Prepare the Connection: Ensure the electrical connection or wire splice is secure and free of sharp edges that could damage the tubing.
- Slide Tubing On: Slide the cut piece of heat shrink tubing over one end of the wire or component, positioning it to cover the desired area completely.
- Apply Heat: Using a heat gun, apply even heat to the tubing. Start from one end and work your way to the other, rotating the wire or component to ensure uniform shrinkage. The tubing will begin to shrink and conform tightly to the shape of the underlying material.
- Inspect: Once the tubing has fully shrunk and appears tight and smooth, remove the heat. Allow the tubing to cool completely before handling or subjecting it to stress. A properly shrunk tube will be firm and provide a sealed, insulated covering.

5. Maintenance
Dorman heat shrink tubing requires minimal maintenance once applied. Ensure it is not exposed to excessive abrasion or sharp objects that could compromise its integrity. Store unused tubing in a cool, dry place away from direct sunlight to maintain its material properties and effectiveness.
6. Troubleshooting
Tubing does not shrink properly:
- Ensure the heat source is adequate and applied evenly. A heat gun is recommended for consistent results.
- Verify the heat is applied for a sufficient duration.
- Check that the tubing size is appropriate for the wire or component; tubing that is too large may not shrink tightly enough.
Tubing appears loose after shrinking:
- Reapply heat evenly, ensuring all sections have fully shrunk.
- Consider using a smaller diameter tubing if the current size is consistently too loose for the application.
