Do's and Donts
✅ Do’s
🛠️ Use for secure wire connections – Ideal for automotive, outdoor lighting, marine applications, and solar systems.
🔥 Properly solder wires before shrinking – Ensure a solid electrical connection before heat-shrinking the waterproof seal.
💧 Verify full shrink coverage – Apply heat evenly so the tubing fully seals around the wires, keeping moisture out.
❌ Don’ts
❌ Don’t skip soldering – Simply crimping or twisting wires without solder reduces connection reliability.
🌡️ Don’t overheat – Excessive heat can damage the connector or insulation.
🌧️ Don’t submerge long-term – Waterproof protects against rain and splashes, but avoid permanent underwater use.
