Set of connectors and heat-shrinkable tubes INNE URZ4053 — 678 pieces

Set of connectors and heat-shrinkable tubes INNE URZ4053 — 678 pieces is a comprehensive kit of electrical connectors and insulating tubes designed for creating and repairing wire joints in a range of applications. The kit combines multiple connector types and heat-shrinkable tubing lengths to provide insulated, mechanically secure connections for small wiring tasks. It is supplied by INNE and packaged to suit hobbyists, technicians and general repair work.

Advantages

The kit contains a broad assortment of connectors and heat-shrinkable tubes in one set, which reduces the need to purchase individual components. Heat-shrinkable tubes provide reliable insulation and strain relief after heating, improving connection durability. The variety of connector styles included supports different wire sizes and connection methods, and components are designed for straightforward application without specialized crimping tools in many cases.

Suitable for

• Automotive wiring repairs and additions
• Marine electrical systems and small boat electronics
• Household electrical repairs and appliance maintenance
• Hobby electronics, model building and DIY projects

Key specifications

• Total number of pieces: 678 (mix of connectors and heat-shrinkable tubes)
• Contents include multiple types of electrical connectors and corresponding heat-shrink tubing
• Material: insulated connector materials and thermally shrinkable polymer tubing
• Wire compatibility: assorted wire cross-sections for small to medium gauge wiring
• Function: electrical insulation, mechanical protection and strain relief for wire joints

How to use

Select the appropriate connector and matching heat-shrinkable tube for the wire diameter. Prepare wires by stripping insulation to the recommended length, insert wires into the connector and complete the mechanical connection according to the connector type (crimp, solder or push-fit). Slide the heat-shrinkable tube over the joint and apply heat evenly with a heat gun, lighter or other controlled heat source until the tubing shrinks and adheres around the connection, ensuring full coverage and a snug fit. Allow cooled assembly before subjecting to mechanical stress or electrical load.

Usage recommendations

For best results, use proper wire stripping and crimping tools to ensure secure connections. Apply heat evenly from a safe distance to avoid overheating surrounding insulation or components. Choose connectors and tubing sizes that closely match the wire gauge and intended environment; for outdoor or marine use consider additional sealing or corrosion-resistant practices.
