Thomas & Betts STA-KON 2RA18X Butt Splice Wire Cap Connector 18 AWG Max Red Vinyl

SKU CH-A89Q-KHQP7

Red vinyl-insulated butt splice joins 22–18 AWG wires with a crimp connection rated to 600 V and 221 °F

  • Color familyRed
  • Product typeElectrical Connectors
  • Handles 18 AWG maximum wire size for secure splices
  • Vinyl insulation rated to 221°F for thermal durability
  • Brazed seam construction prevents barrel separation under stress
  • UL E9809 listed for verified safety compliance
  • Tin-plated copper body resists corrosion for lasting conductivity

Splice connector for 18 AWG wire

This crimp butt splice joins two solid or stranded conductors up to 18 AWG and down to 22 AWG. The vinyl-insulated barrel is colour-coded red for quick size identification. It suits automotive, marine and general low-voltage wiring tasks where a compact, insulated joint is required.

600 V rating and 221 °F limit

The connector is rated for 600 volts maximum and a continuous operating temperature of 221 degrees Fahrenheit. Vinyl insulation remains flexible within this range but will degrade if exposed to higher heat or solvents. Crimp-only termination means no soldering equipment is needed, yet the joint cannot be reused once compressed.

Brazed seam and tin-plated copper

A brazed seam prevents the barrel from splitting under crimp pressure, while tin-plated copper resists corrosion in damp environments. The 1.13 inch overall length and 0.17 inch barrel bore keep the splice slim for tight loom routing. Compatible crimp tools include ERG4001, WT112M, WT145C and WT2000 models for reliable termination.

Questions about this item

Should I choose the red 18 AWG max butt splice or a different colour for my wire size?

The red vinyl insulation identifies the 22 to 18 AWG range; select this connector when your conductors fall within that gauge window.

What does the 600 V rating mean once the splice is crimped in my circuit?

The 600 V maximum voltage is the insulation withstand limit after a proper crimp; do not exceed it in the installed application.

Which crimp tools work with the brazed-seam barrel on this STA-KON connector?

Compatible installation tools include ERG4001, WT112M, WT145C and WT2000 for a reliable crimp on the tin-plated copper barrel.
