Kuject SSP100R Solder Seal Wire Connectors, Red, 22–18 AWG, 100-Pack
Product description
For splicing wires in automotive, marine, boat, or home projects, Kuject SSP100R connectors combine a solder ring and heat-shrink sleeve in one connection. Apply heat with a heat gun to join and seal the wires without a separate crimping step.
The transparent sleeves let you see the connection as you work, while the red connectors are sized for 22–18 AWG wire. A 100-piece pack provides connectors for multiple repairs or wiring tasks.
Two hot-melt adhesive rings help seal each splice against moisture and abrasion. That makes this format useful where a protected wire joint matters, including vehicle and marine wiring.
Technical overview
- Type: Solder seal heat-shrink butt connectors
- Wire size: 22–18 AWG
- Color: Red
- Quantity: 100 connectors
- Shrink ratio: 3:1
- Tool: Heat gun
- Design: Transparent sleeve with solder and two hot-melt adhesive rings
Unlike a conventional butt connector that relies on a crimping step, these sleeves use heat to melt the solder ring and shrink the tubing around the wire splice. The integrated format is intended for joining wires without a separate soldering or crimping operation. Once connected, the sleeve can bend to fit a confined area, which is useful when wiring access is limited.
Practical tips
Match the connector to 22–18 AWG wire and use a heat gun to warm the sleeve evenly. Rotate the connector during heating so the solder ring melts across the exposed wires and the tubing shrinks around the joint. The clear body gives you a view of the connection during this process. The two adhesive rings help form a seal, making the connectors suited to wiring tasks where exposure to moisture or abrasion is a consideration.
A practical use is joining wires in a vehicle or boat repair where the splice needs a protective sleeve and the work area calls for a compact connection. For this heat-applied approach, the heat gun is the required tool, it handles both the soldering and heat-shrink steps.
Getting the most from it
Plan the wire route before making the splice, especially in a narrow space. With the wires positioned, center the connection in the sleeve and apply heat evenly while turning it. This helps the solder ring melt around the splice and the tubing form around the joint. The flexible sleeve can then accommodate bends after connection, which is helpful when routing wiring around surrounding components.
Customers often describe the connectors as easy to use with a heat gun and versatile across wiring projects, one reported using them with WS2811 LED lights. Feedback on the soldering process is mixed, with some buyers saying it takes substantial heat or that connections can separate after repeated use. Even heating and selecting the specified wire gauge are practical considerations for this style of connector.
Before you decide
What wire size do these connectors fit? They are designed for 22–18 AWG wire, so match the connector to the wire gauge for the project.
What tool is needed to make a connection? Use a heat gun to melt the solder ring and shrink the sleeve around the splice.
Are they intended for moisture-exposed wiring? The sleeves have two hot-melt adhesive rings to help seal the splice against moisture and abrasion, making them suitable for marine and automotive wiring applications.
When it makes sense
Kuject SSP100R is a practical fit for projects that call for a heat-applied wire splice in 22–18 AWG, particularly automotive, marine, boat, or home wiring. The integrated solder-and-shrink design, transparent sleeve, and adhesive sealing rings bring joining and protection into one connector, while the 100-piece pack supports multiple wiring tasks.
