Questions about this product
- Do I need a crimper to use these solder seal connectors, and how do I heat them?
- You can use an AWG 22-18 insulated terminal crimper to secure the connection first. Then, apply heat with a heat gun or controlled flame to melt the solder and shrink the sleeve. The internal adhesive activates at around 110°C, while the solder fully melts at 135°C.
- What wire sizes do these red connectors fit, and how many come in the pack?
- This kit includes 50 red connectors designed specifically for AWG 22 to AWG 18 wire gauges. They have an unshrunk outer diameter of about 4.8 mm and shrink down to roughly 3.2 mm. This size is ideal for common thin-gauge electronics and automotive wiring.
- Can I use these wire connectors in wet outdoor areas or marine environments?
- Yes, these connectors are perfect for wet environments because they have an IP67 waterproof rating. The internal adhesive melts to seal out moisture, salt, and corrosion. They also withstand extreme temperatures ranging from -55°C up to 125°C.
