1640 Pcs Pre-Insulated/Uninsulated Cable Lugs Crimp Terminals Insulated Wiring Ferrules Butt Connectors Electrical 12-22 AWG for Electrician Splicing Projects 0.5/1/1.5/2.5/4mm²

【Cable End Kits】: The 1640-piece crimp terminal set includes 590 pre-insulated cable ends and 1050 uninsulated crimp terminals. Interface type: AC/DC. Operating frequency: low frequency.

【Uninsulated Butt Connectors】: 5 types of uninsulated electrical terminals: 0.5 mm² (400 pieces), 1.00 mm² (200 pieces), 1.5 mm² (200 pieces), 2.5 mm² (150 pieces), 8 mm length.

4.00 mm² (100 pieces), 9 mm length.

【Pre-Insulated Lugs】: Insulated wire ferrules with PVC heads in 5 types: red 0.5 mm² (200 pieces), blue 1.00 mm² (150 pieces), black 1.5 mm² (100 pieces), yellow 2.5 mm² (80 pieces), green 4.00 mm² (60 pieces).

【Application】: Uninsulated crimp ferrules effectively prevent wire ends from becoming exposed or broken. Copper wire ferrules have good electrical and thermal conductivity, providing reliable connections. These ferrules, designed with an insulating flare, facilitate wire insertion. 【Tin-Plated Copper】: The electrical end connectors are made of red copper, tin-plated to prevent oxidation and rust, making them more durable. Widely used for electrical projects, workshops, automotive electricians, machinery, cars, trucks, motorcycles, etc. 【How to Use】: Remove the wire core from the sheath. The stripped length should be as long as the metal ferrule of the terminal. Place the entire core inside the ferrule of the wire end without exposing it, then crimp the terminal. Before doing so, please adjust the crimping tool according to the thickness of the wire core.
