Ecm Industries Llc GBX-TK Heat Shrink Butt Splice Kit 24 Piece

Product Description

The ECM INDUSTRIES LLC GBX-TK is a 24-piece heat shrink butt splice kit designed for making secure, moisture-resistant wire connections across a range of conductor sizes. The kit covers 22 AWG through 10 AWG wire, making it suitable for low-voltage control wiring, field repairs, and general electrical splicing tasks. Heat shrink butt splices provide a dual function: they create a reliable mechanical and electrical connection while the heat shrink tubing seals the joint against moisture and contaminants. Electricians, HVAC technicians, and other trade professionals who need a compact, organized splice assortment on the job will find this kit practical for service calls and installation work.

This kit is suited for residential and light commercial wiring applications where insulated butt splices are required. The 22-10 AWG range covers most low-voltage thermostat wire, control circuits, and general branch-circuit conductors encountered in HVAC, electrical, and related trades. The compartmentalized case keeps splice sizes separated and accessible in a tool bag or service van, reducing time spent sorting hardware on the job.

Key Features

• 24 heat shrink butt splices across a 22-10 AWG wire range
• Heat shrink construction seals connections against moisture and environmental exposure
• Compartmentalized case organizes splices by wire gauge for quick access
• Compact carded format stores easily in a tool bag or parts kit
• Covers multiple conductor sizes in a single kit, reducing the need for separate assortments

Compatibility

Designed as a general-purpose heat shrink butt splice assortment compatible with solid and stranded conductors in the 22-10 AWG range, suitable for low-voltage control wiring and standard electrical splicing applications.

Installation Notes

Heat shrink butt splices are installed by licensed electricians or qualified trade technicians following applicable NEC guidelines. Always de-energize the circuit before making any splice connection. Use a calibrated heat gun to shrink the tubing evenly around the connection — open flame tools are not recommended. Inspect the finished splice for complete shrinkage and secure mechanical hold before re-energizing the circuit.
