Description

This 10-pack of large-diameter red heat shrink tubing is designed for professional-grade insulation, protection, and bundling of substantial cables, hoses, or multi-wire connections. Each tube measures 300mm (approx. 12 inches) in length with a 20mm starting diameter, offering a versatile solution for heavy-duty automotive, marine, and industrial applications.

Key Features & Specifications:

  • Material: Red Polyolefin (Flexible, Durable)

  • Supplied Diameter: 20mm (Before Shrinking)

  • Recovered Diameter: ~10mm (After Shrinking - 2:1 Ratio)

  • Length: 10 pieces, each 300mm long

  • Shrink Temperature: 105°C

  • Operating Temperature Range: -50°C to +125°C

  • Shrink Ratio: 2:1

Core Benefits & Applications:

  • Harness Protection: Ideal for creating a durable, abrasion-resistant outer jacket over large wire harnesses, multiple battery cables, or hydraulic/pneumatic hose bundles.

  • Insulation & Environmental Seal: Provides excellent electrical insulation and a basic seal against moisture and dust for heavy-gauge connections on starters, inverters, or welding equipment.

  • Strain Relief & Organization: Consolidates and organizes thick, unwieldy cables into a single, manageable sleeve, preventing tangles and reducing wear from vibration.

  • High-Visibility Identification: The bright red color allows for easy circuit identification or safety marking in complex installations.

How to Use: Slide the tube over the cable bundle or connection. Apply heat evenly with a heat gun, moving continuously until the tube shrinks tightly and conforms to the shape. For large diameters, heat in a circular pattern and work in sections for an even finish.

  • I have made multiple purchases from this company, and their service consistently exceeds my expectations. Last week, I urgently needed some parts and, based on my previous positive experiences, I chose TINKR once again. As expected, their service was exceptional. A special thanks to Greg at TINKR for a job well done.
