Conversions Tech Heat-Shrink Butt Splice Connector (22–18 AWG, Red) — Adhesive-Lined Sealed Crimp Splice (Bag of 100)
The Conversions Tech Heat-Shrink Butt Splice (22–18 AWG) is a precision inline crimp splice connector designed for reliable electrical continuity and environmental sealing in compact wiring applications. Built with a tin-plated copper splice barrel and a heat-shrink insulation sleeve with hot-melt adhesive liner, this connector forms a tight, moisture-resistant bond to wire insulation during installation—helping protect connections from corrosion, vibration, and ingress in automotive, marine, and industrial environments.
Supplied in bags of 100, this format is ideal for service teams, OEM harness assembly, maintenance departments, and electrical contractors who need consistent, production-ready quantities.
Key Engineering Advantages
- Compact AWG range: Optimized for 22–18 AWG stranded copper conductors.
- Sealed insulation system: Heat-shrink tubing with hot-melt adhesive liner activates during recovery to help block moisture and contaminants.
- Low-resistance termination: Tin-plated copper barrel supports stable conductivity and corrosion resistance.
- Inline butt splice geometry: Clean, space-efficient wire-to-wire splicing.
- Production-friendly packaging: Supplied in bags of 100 for inventory control and job-site efficiency.
Typical Applications
- Automotive and powersports harness repairs
- Marine electronics and low-current circuits
- Industrial controls and instrumentation wiring
- Security, lighting, and low-voltage accessory installations

Installation Best Practices
- Strip conductors to fully seat copper inside the splice barrel without exposed strands.
- Use a crimp tool rated for 22–18 AWG butt connectors to ensure proper compression.
- Apply even heat with a controlled heat gun until the tubing fully recovers and adhesive flows at both ends.
- Avoid sharp bends at the splice to maintain strain relief and long-term reliability.
FAQs
1) What wire sizes does this connector support?
This butt splice is designed for 22–18 AWG stranded copper conductors.
2) How many connectors are included?
Each unit is supplied in a bag of 100 heat-shrink butt splice connectors.
3) Is this splice water-resistant?
Yes. When properly heated, the adhesive-lined heat-shrink insulation helps seal the connection against moisture.
4) What material is the barrel made from?
The splice barrel is tin-plated copper for conductivity and corrosion resistance.
5) Can this be used in automotive wiring?
Yes. It is commonly used in automotive, powersports, and accessory circuits within the supported AWG range.
6) Do I need special tools?
A quality crimp tool designed for 22–18 AWG butt splices and a heat gun are recommended.
7) What does the red color indicate?
Red insulation indicates the 22–18 AWG wire size range for quick visual identification.
8) Is this suitable for vibration environments?
Yes. The sealed heat-shrink design provides strain relief and is commonly used in vibration-prone applications.
9) Can this be used outdoors?
When properly installed, it is suitable for outdoor and exposed locations where moisture protection is required.
10) How do I verify a proper installation?
After shrinking, the tubing should be fully recovered with visible adhesive flow at both ends and no exposed conductor.
11) Is this intended for OEM production use?
Yes. The bag-of-100 packaging and consistent sizing make it suitable for OEM harness assembly and maintenance operations.
