Panduit

Panduit BS18-C Butt Splice Connector 18 AWG Copper

SKU CH-EMPN-QTZCY

A copper butt splice connector for crimping 22 to 18 AWG wires, rated to 2,000 V and 302 °F with a brazed seam and tin-plated barrel

  • TypeElectrical Connectors
  • Crimps 18 AWG wire securely with brazed seam barrel
  • Handles up to 2,000 V for high-voltage applications
  • Operates at 302 °F maximum temperature for harsh environments
  • Tin-plated copper body resists corrosion and ensures conductivity
  • Meets CSA C 22.2 No. 65 and UL 486C safety standards

Purpose and fit

The Panduit BS18-C is a bare copper butt splice designed for crimp terminations on 18 to 22 AWG conductors. It suits installers joining solid or stranded wire in panels, harnesses or automotive looms where insulation is supplied separately.

Wire range

The connector accepts a minimum of 22 AWG and a maximum of 18 AWG, with a barrel inside diameter of .076 in and outside diameter of .14 in. Using wire outside this range will prevent a reliable crimp and may fail inspection.

Thermal and electrical limits

Rated to 302 Degrees F maximum operating temperature and 2,000 V, the tin-plated copper body meets UL 486C and CSA C 22.2 No. 65. The brazed seam resists opening under thermal cycling, and the crimp-style termination adds no active cooling requirement.

Questions about this item

What does the 18 AWG maximum wire size mean when I am crimping this splice?

It accepts solid or stranded copper conductors up to 18 AWG and down to 22 AWG, so a single splice covers that whole range.

The UL 486C and CSA C22.2 No. 65 listings — what do they cap in practice?

They certify the connector for up to 2,000 V and a maximum operating temperature of 302 °F in copper wiring systems.

With a 0.62 in overall length and 0.14 in barrel OD, what clearance do I need in a tight harness?

Allow roughly 0.62 in of straight run for the body plus room for the crimp tool jaws around the 0.14 in barrel.
