  • Tin-plated copper barrel ensures low-resistance crimp connections
  • Rated 600 V meeting MIL-T-7928 and UL E9809 standards
  • Compatible with ERG4001, WT112M, WT145C crimp tools

Wire splice for 22-18 AWG

The Sta-Kon 2RA18 is a crimp butt splice connector built for wires from 22 AWG to 18 AWG. Red nylon insulation identifies the size range and withstands up to 221 Degrees F. A tin-plated copper barrel with an overlapped seam provides a secure crimp joint rated for 600 V maximum voltage.

Crimp tooling and space savings

The connector accepts hand tools such as the ERG4001, WT112M and WT145C for a controlled crimp without solder. Its 1.19 in overall length and 0.115 in barrel inside diameter keep the joint compact inside tight harnesses or junction boxes. The nylon body resists vibration and chemical exposure in automotive and industrial environments.

Step up from bare wire twists

This splice replaces twisted wire nuts or tape joints that can loosen over time. The crimp termination meets MIL-T-7928 and UL E9809 standards for reliable conductivity. The jump is worth it when a permanent, insulated connection is required for 22 to 18 AWG circuits in panel wiring, vehicle repair or appliance assembly.

Questions about this item

What is the highest temperature this butt splice connector can withstand before the nylon insulation degrades?

The nylon insulation is rated for a maximum operating temperature of 221 degrees Fahrenheit.

How much heat does the crimped copper barrel generate when carrying continuous current at the 600 V rating?

Heat rise depends on the actual current load and wire gauge used; the connector itself is rated for 600 V maximum voltage.

Which crimping tool models are required to properly terminate this connector on 22-18 AWG wire?

Compatible installation tools include ERG4001, WT112M and WT145C.
