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.

Achieve permanent, waterproof electrical connections with these 50PCS Heat Shrinkable Wire Connectors. The SST21 sleeves feature a pre-installed solder ring and adhesive sealant, creating a strong, insulated splice rated for AWG 22-18 wire. This professional-grade solution ensures superior conductivity and long-term reliability in demanding environments. Features and Benefits - Tinned Solder Ring & Adhesive Lining - Melts and flows during heating to create a strong mechanical and electrical bond while the adhesive forms a waterproof, corrosion-resistant seal. - High-Quality Polyolefin Sleeve - Provides excellent insulation, flame retardancy (UL VW-1 certified), and resistance to abrasion, chemicals, and UV exposure for durable protection. - Wide Compatibility for AWG 22-18 - Accommodates a common range of wire gauges, making this 50-piece kit versatile for various projects without needing multiple connector sizes. - Color-Coded Sleeves (Red) - Allows for quick visual identification of connector size and ensures you select the correct sleeve for the wire gauge you are working with. - Simple Heat Application - Using a standard heat gun, the sleeve shrinks uniformly in seconds, activating the solder and sealant for a fast, professional finish every time. Applications - Automotive & Marine Wiring Repairs - Ideal for splicing wires in vehicles, boats, or RVs where vibration and moisture resistance are critical for safety and longevity. - Outdoor Lighting & Irrigation Systems - Create waterproof splices for low-voltage landscape lighting, sprinkler system solenoids, and other exterior electrical installations. - DIY Electronics & Appliance Repair - Perfect for securing connections in home projects, repairing small appliances, or building custom cables with a clean, insulated finish. - Professional Electrical Maintenance - A reliable, time-saving solution for electricians and technicians performing field repairs on control wiring, sensors, and low-voltage circuits.
