Heat-Shrink Tubing 4:1 Small MDPC-X Pre-Cut, Blue — 50 pieces

Pre-cut MDPC-X heat-shrink tubing with a 4:1 shrink ratio in small size, blue colour, pack of 50 pieces. This heat-shrink tubing is intended for insulating and protecting wire connections, solder joints and cable assemblies where a high shrink ratio is required. The pre-cut pieces simplify installation and save time compared with cutting from a continuous sleeve, while the durable material provides mechanical protection, strain relief and basic electrical insulation for DIY electronics, PC modding and repair tasks.

Advantages

The MDPC-X small 4:1 heat-shrink tubing offers consistent shrink performance and reliable fit on a variety of cable diameters after heat application. Pre-cut lengths ensure uniform coverage and reduce preparation time. The blue colour provides visual identification for wiring runs or phase marking. The tubing material resists wear and provides added strain relief at connection points without adding significant bulk.

Suitable for

• Insulating solder joints and wire splices in electronics repair
• Protecting and tidying cable assemblies in PC modding and custom builds
• Providing strain relief and abrasion protection on small-diameter wires
• Color-coding wires and connectors for easier identification

Key specifications

• Shrink ratio: 4:1
• Size category: small (pre-cut pieces sized for small-diameter cables)
• Quantity: 50 pieces per pack
• Colour: blue
• Material: heat-shrink polymer designed for electrical insulation and mechanical protection

How to use

Select a pre-cut tube that fits over the connector or wire before making the final solder or crimp connection. Slide the tubing into position, then apply heat evenly using a heat gun, soldering iron with appropriate tip, or other controlled heat source until the tubing has fully contracted and conforms to the underlying shape. Allow the tubing to cool and verify that it forms a snug, wrinkle-free sheath around the cable or joint.

Usage recommendations

For best results, use a temperature-controlled heat gun and maintain a consistent distance while heating to avoid overheating or scorching. Ensure the tubing fully covers solder joints or exposed conductors and allow cooling time before handling. Use the blue colour for visual organisation of multiple cables and choose the small size when working with thin wires or tight spaces.
