Panduit BSV18X-LY Pan-Term® Vinyl Butt Splice Connector
The Panduit BSV18X-LY is a vinyl-insulated butt splice connector designed for field splicing, repair, and extension of 18–22 AWG solid and stranded copper conductors in commercial electrical and low-voltage installations. Part of Panduit's Pan-Term® connector family, this red-coded splice features extended wire entry and an internal wire stop that ensures consistent crimp depth across every termination—critical when you're running dozens of splices in a single cabinet or junction box and need repeatable mechanical and electrical performance.
Key Features
- 18–22 AWG wire range for standard building wire, control circuits, and low-voltage signal runs
- Extended wire entry accommodates conductors with thicker insulation jackets
- Internal wire stop prevents under-insertion and ensures full contact with the crimp barrel
- Zinc-plated brass barrel for corrosion resistance and reliable conductivity
- Red vinyl insulation color-codes wire gauge and provides 600 V rated dielectric barrier
- Compatible with Panduit CT-100, CT-1550, CT-1551, CT-2300/ST, and CT-2500/L crimp tools
- 1.03" overall length, 0.17" width—compact profile fits tight enclosures
- 50-piece package for job-site convenience
Field splicing is a reality in commercial security, access control, and fire alarm installations—whether you're repairing a cut conductor in a plenum run, extending a wire that came up short during rough-in, or consolidating multiple home runs in a centralized equipment rack. The BSV18X-LY is engineered to deliver gas-tight, vibration-resistant connections that won't degrade over time. The extended wire entry is sized to accept thicker jacket materials (common in plenum-rated and shielded cables), and the internal stop ensures that both conductors seat fully into the crimp barrel before you apply pressure. This eliminates the guesswork that leads to weak crimps, high resistance joints, and intermittent faults six months after turnover.
The red vinyl insulation serves two purposes: it color-codes the connector for 18–22 AWG wire per industry convention, and it provides a 600 V rated dielectric barrier that meets NEC requirements for insulated splices in accessible locations. The zinc-plated brass barrel resists oxidation in humid or coastal environments, and the serrated inner surface deforms the conductor strands during crimping to create a cold-weld joint with contact resistance comparable to a continuous wire. For best results, use a ratcheting crimp tool from Panduit's CT series—these tools apply controlled force and won't release until the crimp cycle is complete, ensuring uniform compression across the entire barrel length.
This 50-piece package is sized for integrators and electricians who need a working supply on the van without committing to a full 500-piece carton. Each connector is manufactured to Panduit's quality standards and is widely cross-referenced against legacy part numbers from AMP, Thomas & Betts, 3M, and Molex—making it a drop-in replacement when you're matching existing inventory or fulfilling a spec callout. When jobsite documentation calls for listed components and repeatable termination quality, the BSV18X-LY delivers the reliability that keeps punch-list callbacks off your schedule.
