## Summary description

Prolech quick connector for electrical conductors, suitable for solid or stranded wires with cross-sections from 1.0 to 2.5 mm². Yellow insulated sleeve, supplied as a pack of 100 pieces. Designed for fast, tool-assisted or hand insertion splicing in domestic and light industrial wiring, repairs, and prototyping where reliable insulated connections are required.

## Long description

The Prolech quick connector 1.0–2.5 mm² yellow pack of 100 is an insulated inline splicing sleeve designed for fast electrical connections of solid and stranded conductors within a 1.0 to 2.5 mm² cross-section range. The connector features a yellow insulated outer sleeve and an internal conductive element that secures and electrically joins wires with minimal preparation. Supplied in a convenient pack of 100, this product is intended for domestic wiring tasks, small repairs and prototype assemblies where insulated, reliable splices are needed.
Advantages
The connector offers quick, repeatable splicing without soldering, enabling faster installation compared with traditional methods. Its insulated sleeve provides basic protection against accidental contact and short circuits when used according to standard wiring practice. The design accommodates both solid and stranded conductors, reducing the need for multiple connector types and simplifying inventory for common wire cross-sections from 1.0 to 2.5 mm².
Suitable for (tasks / use cases)
Household wiring repairs and modifications
Light industrial electrical connections and maintenance
Automotive low-voltage wiring and accessory installations
Prototyping and small electronics assemblies
Temporary or semi-permanent splices in control panels and junction boxes
Key specifications
Compatible conductor cross-section: 1.0–2.5 mm²
Suitable conductor types: solid and stranded copper wire
Insulation: colored insulated sleeve (yellow)
Pack quantity: 100 pieces
Connection type: inline quick splice with internal conductive sleeve
How to use
Strip the conductor insulation according to common practice, insert both wire ends into the connector until they meet the internal conductive element, and apply hand pressure or a suitable insertion tool to complete the splice. Ensure the wires are fully seated and that the insulating sleeve covers exposed conductor. Verify mechanical retention and electrical continuity with appropriate testing equipment before applying power.
Usage recommendations
Use the connector within its specified conductor range (1.0–2.5 mm²) and with copper conductors only. Avoid use on conductors with incompatible insulation thickness or on high-current circuits beyond the connector's design capability. For installations exposed to moisture, vibration, or high temperatures, consider additional sealing, strain relief, or an alternative connector rated for those conditions.
