Burndy SP18BG25 Vinyl-Insulated Copper Butt Splice

Burndy Vinyl-Insulated Copper Butt Splice, 22-18 AWG

The Burndy vinyl-insulated copper butt splice is built to join conductors in the 22-18 AWG wire range. Machined from seamless copper for a continuous, high-conductivity current path, this splice features a funnel entry that guides stripped wire into the barrel and a tin-plated finish that helps resist corrosion over the life of the connection. A vinyl insulation sleeve covers the completed compression joint, shielding the splice point from accidental contact and moisture while keeping the connection compact enough for tight enclosures, terminal blocks, and junction boxes. It is a straightforward, professional-grade way to make a dependable in-line splice on small-gauge control, signal, and lighting circuits.

Key Features

• Wire Range: Sized for 22-18 AWG conductors, making it well suited for small-gauge control, signal, and lighting circuit wiring.
• Seamless Copper Construction: A seamless copper barrel provides a continuous, high-conductivity current path with no weld seam to compromise the joint.
• Funnel Entry Design: The funnel-shaped entry guides stripped conductors into the barrel, easing installation and reducing the chance of strand damage during insertion.
• Compression-Style Connection: Engineered as a compression splice, delivering a mechanically secure, low-resistance joint between conductors once crimped.
• Tin-Plated Finish: Tin plating over the copper barrel helps resist corrosion and oxidation, supporting long-term conductivity and connection integrity.
• Vinyl Insulation Sleeve: A vinyl insulating cover shields the completed splice, helping guard against accidental contact and moisture intrusion after crimping.
• Compact In-Line Profile: The butt-splice format keeps the finished connection low-profile, making it easier to route and manage inside crowded enclosures and junction boxes.
