Heat-Shrink Sleeves with Glue Silver model 11379 — 328 pcs

Pack of 328 heat-shrink sleeves with internal adhesive from Silver, model 11379, designed to provide reliable insulation and mechanical protection for wire joints, connectors and cable terminations. These heat-shrink tubes shrink uniformly when heated and form a sealed, adhesive-lined barrier that protects against moisture, abrasion and short circuits. The set covers a range of small to medium diameters, offering a practical solution for electrical repairs, harnessing and maintenance tasks in home, automotive and electronics applications.

Advantages

Heat-shrink sleeves with internal glue combine thermal shrinkage and an adhesive lining that flows and bonds as the tube contracts, ensuring a tight waterproof seal and strain relief. The large pack of 328 pieces reduces the need for frequent reordering and provides spare parts for multiple projects. Silver's material composition resists common environmental factors such as oils and typical mechanical wear, delivering consistent electrical insulation and longer-lasting joints when applied correctly.

Suitable for

• Insulating and protecting soldered or crimped wire joints in domestic electrical repairs
• Automotive wiring repairs and harness insulation
• Sealing connections in small electronics and appliances
• Strain relief and abrasion protection for exposed cable terminations

Key specifications

• Pack quantity: 328 pieces covering a range of small to medium diameters
• Material type: heat-shrinkable tubing with heat-activated adhesive lining
• Function: electrical insulation, mechanical protection, moisture sealing and strain relief
• Application temperature: shrinks when heat is applied (standard heat gun or lighter, controlled heat source recommended)
• Typical shrink ratio: designed for reliable contraction to form a tight fit (follow visual fit during application)

How to use

Select a sleeve with an appropriate diameter so that it fits loosely over the joint before heating. Slide the sleeve into position over the exposed area and apply steady, even heat using a heat gun set to an appropriate temperature or another controlled heat source until the tubing uniformly conforms to the underlying wires and the adhesive lining flows to create a seal. Allow the sleeve to cool undisturbed so the adhesive cures and the joint stabilizes. Trim excess tubing before installation if necessary.

Usage recommendations

For reliable results, clean and dry wire surfaces before applying the heat-shrink sleeve, avoid open flames close to sensitive components, and use a temperature-controlled heat gun where possible. Verify fit and insulation integrity after cooling. Store the sleeves in a cool, dry place away from direct sunlight to maintain material properties.
