Product Information
Full details
This guide is for electricians and DIY enthusiasts needing secure wire connections. The Loops 6.4mm Red Heat Shrink Ring Terminals provide a robust, insulated, and weatherproof seal for 22-18 AWG wires. While offering excellent protection, their specialized nature means they require a heat source for proper application, unlike standard crimp terminals.

FAQs
What is the purpose of the adhesive lining?
The adhesive lining melts and flows when heated, creating a watertight and vibration-resistant seal around the wire and terminal, protecting the connection from environmental factors.
Can I use these on thicker wires?
No, these terminals are specifically designed for wire gauges between 22 AWG and 18 AWG. Using thicker wire may prevent proper insertion and crimping, and could compromise the seal.
What heat source should I use?
A heat gun is recommended for best results. A high-temperature hairdryer may work for smaller applications, but a dedicated heat shrink torch or heat gun provides more consistent and adequate heat.
How do I know when the connection is secure?
The heat shrink tubing will appear tight and smooth around the connection. You should see a small amount of the internal adhesive gently flow out from the ends of the tubing, indicating a complete seal.
What does the red color signify?
In electrical wiring, red is the standard color code for terminals designed for 22-18 AWG wire, helping with identification and compliance.
Are these reusable?
No, once the heat shrink tubing is applied and sealed, the terminal cannot be removed or reused.
Troubleshooting
Heat shrink tubing not shrinking uniformly
Ensure consistent heat application. Move the heat source slowly and evenly over the entire length of the tubing. Avoid concentrating heat on one spot.
Adhesive not sealing the connection
Ensure the tubing is heated sufficiently for the adhesive to melt and flow. Check that the wire gauge is within the 22-18 AWG range specified for this terminal.
Connection feels loose after crimping
Re-crimp the terminal using appropriate pressure. Ensure the wire is stripped to the correct length and fully inserted into the terminal barrel before crimping. Use a high-quality crimping tool.
Wire insulation melting during heat application
Reduce the heat intensity or move the heat source further away. Apply heat more quickly and evenly to shrink the tubing before the wire insulation degrades.
Pros and Cons
Pros
- Provides a watertight and vibration-resistant seal.
- Color-coded for easy identification.
- Durable and long-lasting connection.
- Suitable for automotive, marine, and general electrical work.
- Quick and easy application with a heat source.
Cons
- Requires a heat gun or other heat source for installation.
- Not reusable once applied.
- Specific wire gauge range (22-18 AWG) limits broader application.
- Can be less forgiving of over-crimping than non-heat shrink options.
Setup, Compatibility & Care
Setup:
- Prepare Wire: Strip the end of the wire to the appropriate length (typically 5-7mm for this terminal size).
- Insert Wire: Slide the stripped wire end into the ring terminal until it is fully seated.
- Crimp: Use a suitable crimping tool for 22-18 AWG wire to ensure a firm mechanical connection between the wire and the terminal barrel.
- Apply Heat: Use a heat gun or a specialized heat shrink torch. Apply heat evenly to the tubing, starting from the center of the connection and working outwards towards the ends. The tubing will shrink and the internal adhesive will melt and flow, creating a seal.
Compatibility:
- Wire Gauge: Compatible with wires ranging from 22 AWG to 18 AWG.
- Screw Size: The 6.4mm diameter ring is designed for M4 (or #8) screws or posts.
- Environment: Suitable for automotive, marine, industrial, and general electrical applications.
Care:
These are single-use components. Once installed, they do not require ongoing maintenance. Ensure the connection is protected from excessive physical stress after installation. Avoid exposing the terminals to extreme temperatures beyond their rated operating range (typically -55°C to 125°C).
