SG Tool Aid 23221 3/16" Double Wall Adhesive Heat Shrink Tubing 20-Pack

The SG Tool Aid 23221 double wall adhesive heat shrink tubing provides professional-grade wire protection and sealing for automotive, marine, and electrical applications. Each tube features a dual-layer construction with an inner adhesive lining that melts when heated, creating a waterproof, strain-relieved connection that protects against moisture, corrosion, and abrasion.

Key Features:

• 3/16" diameter double wall heat shrink tubing with adhesive inner layer
• 20 pieces per bag for multiple repairs and projects
• 6" length tubes provide ample coverage for most connections
• Includes red and black tubes for color-coded wiring identification
• Adhesive-lined construction creates waterproof, insulated seal when heated
• Ideal for marine, automotive, trailer, and outdoor electrical connections

Simply slide the tube over your wire connection, apply heat with a heat gun or torch, and watch as the tubing shrinks tight while the inner adhesive melts to form a secure, environmental seal. The dual-wall design offers superior protection compared to standard heat shrink tubing, making it perfect for harsh environments where moisture and vibration are concerns.
