Insulated Butt Connectors — BV / PVT Series
Vinyl-insulated butt connectors for in-line splicing of copper wires (0.5–50 mm² / 22–#2 AWG).
Full BV long-body range plus compact PVT short-body options.
Color-coded sleeves for fast size ID; consistent barrels for reliable crimps.
Ideal where insulated butt connectors must deliver a strong, low-resistance splice with strain relief.
Overview
WILLELE BV / PVT Series insulated butt connectors create secure in-line splices for control panels, vehicles and general wiring.
The long-body BV style maximizes crimp area, while the compact PVT short-body saves space in dense panels.
Color sections follow industry practice for quick selection and reliable terminations.
- Vinyl insulation adds grip and dielectric protection; color indicates wire size.
- Barrel geometry supports repeatable crimps with standard ratchet tools.
- Designed for copper conductors; tin-plated for corrosion resistance.
- Ideal wherever insulated butt connectors must provide a strong, low-resistance splice.

Applications
- In-line splices in control panels, machinery and automotive wiring
- Space-constrained areas (use PVT short-body)
- Pair with heat-shrink tube for extra strain relief
Ordering Guide
Choose conductor section (AWG/mm²) and body style (BV long-body or PVT short-body), then match barrel ID (DØ) and length.
WILLELE supplies insulated butt connectors from 0.5–50 mm² with typical currents up to 160 A.
