Key Features

• PACKAGE CONTENTS - This 24-18 AWG wire splice kit includes 100pcs 24-18 Gauge tinned copper non-insulated seamless crimp butt connectors with inspection windows, plus 100pcs 3:1 dual wall adhesive-lined heat shrink tubes. Rated 600V, compatible with solid & stranded Class B/C copper conductors. Terminals support both crimping and soldering, suitable for general wiring projects. The included 3:1 dual wall heat shrink tubing features inner thermoplastic adhesive. When heated, the tube contracts firmly while molten glue fully encapsulates wires to form a durable airtight waterproof seal, maintaining stable electrical conductivity long-term.
• MARINE GRADE TINNED COPPER - These inspection window butt connectors use 99.9% pure C11000 Cu-ETP copper coated with thick matte tin plating for outstanding durability. The tin layer prevents oxidation, rust and galvanic corrosion to preserve stable high conductivity. Meeting marine-grade standards, they hold firm electrical connections in damp, salty corrosive environments and feature great wear resistance for long-lasting permanent wiring.
• SEAMLESS TUBULAR BARREL FOR SECURE, ROBUST CRIMPS - These heavy-duty inspection window terminals are engineered for high-amperage wiring applications, featuring thick one-piece seamless pure copper barrels. Seamless structure prevents barrel splitting while crimping — a typical flaw of cheap seamed splices. They offer great conductivity and rigid crimp strength to build pull-resistant, vibration-stable wire joints that never slip loose. Ideal for heavy-load long-term wiring, these copper splices deliver durable, consistent high-performance electrical connections.
• WITH INSPECTION WINDOW - The butt splice wire connectors in this kit come with a central inspection window for instant visual check, so you can easily confirm wires are fully inserted into the barrel. This opening doubles as a solder port for injecting tin solder between wire conductors and terminals. Adding solder through the window reinforces splices and drastically improves pull resistance. While optional, this extra soldering step is highly recommended to create ultra-stable, long-lasting electrical joints.
• 100% ANNEALED ELECTROLYTIC COPPER - Every SVAAR butt splice connector is crafted from full electrolytic copper with professional annealing treatment as an extra production step. Controlled heating at precise temperatures optimizes the copper’s physical traits for superior crimp performance. Annealing relieves internal material stress and hardness, effectively lowering the risk of barrel cracking when crimping. The enhanced ductility delivered by this process is essential to forming tight, damage-free wire splices.
• LONGER LENGTH TUBULAR BARREL - Our butt splices adopt thick, seamless extended copper barrels featuring high tensile strength, outstanding conductivity and corrosion resistance. The lengthened barrel expands wire contact surface, drastically lifting pull resistance and connection safety. The seamless structure delivers firm crimps to prevent wire slippage and maintain stable long-term splices. Compatible with both crimping and soldering for dual-layer reliability: crimping offers robust mechanical fixation, while soldering further reinforces joint strength and electrical performance.
• SAFER DESIGN & EASY TO USE - All butt connectors in this wire splice kit are made of seamless high-conductivity copper with uniform electro-tin plating. The thick barrel creates firm crimps to avoid wire slippage. Dual-side chamfered openings allow smooth, quick wire insertion. An internal center stop prevents over-insertion to maintain consistent, dependable electrical joints. Each splice is fitted with a central inspection window for visual confirmation of full wire seating, simplifying routine checks and quick troubleshooting.
• RECOMMENDED HEAT SHRINK TUBING - For best results with these wire butt splices, we recommend insulating your connections with dual-wall, adhesive-lined heat shrink tubing. When used with the included heat shrink tubing, these butt connectors provide a secure, insulated seal. Adhesive lined design creates a hermetic seal for maximum durability, corrosion resistance and insulation protection. Additionally, the color-coded heat shrink simplifies polarity identification, making installation hassle-free. The wire shrink wraps are all pre-cut into the most common sizes which improve your work efficiency.
• HOW TO CHOOSE AND USE - SVAAR butt splice connectors give you the flexibility to select from a wide range of wire sizes to match your requirements and applications. When crimping, choose the right butt connectors that fit the wire gauge. Note that some cable manufacturers oversize their cable gauges (this is especially common with audio cables), which may prevent a direct fit. We recommend checking the product dimensions to ensure the connectors fit properly before purchasing.
• BUYER CONFIDENCE - Always match the size and gauge of terminals, cables, and lugs to ensure a proper fit. It’s important to use these connectors with compatible copper cables. We recommend double-checking the dimensions to confirm accuracy before purchasing—this ensures your connections are secure and long-lasting. If you encounter any issues, we stand ready to resolve them for you. Everything you need to get started is included here.
