200PCS Solder Seal Wire Connectors Kit, Upgraded Heat Shrink Butt Wire Connectors, Waterproof Electrical Butt Splice Wire Terminals for Marine Automotive Trailer RV Boat Truck Wiring

These butt shrinks are a no brainer. Self soldering, marine grade. Strong hold permanant! I repaired a 120v 20 amp cord and it worked gr8, will do wonders on dv wiring too

Makes wire splicing easy and seals from moisture. Great product.

Was sceptical at first. Definitely worked as described. Must have for wiring that is out in the weather/ trailers.

The YNZDRWA Solder Seal Wire Connectors Kit offers a decent solution for quick and secure wiring in various automotive, marine, and trailer applications. I've used these connectors on multiple projects, and they’ve proven to be quite handy.Pros:- Ease of Use: The connectors are straightforward to use—just heat them up, and they shrink to form a strong, water-resistant seal around the wires.- Waterproof: The waterproof feature works well in environments where moisture or water exposure is a concern, such as marine or trailer wiring.- Good Variety: The 200-piece kit provides a range of sizes, making it versatile enough for different wiring needs.Cons:- Durability: While they work well initially, I found that they can be a bit fragile if exposed to too much heat or movement after installation.- Heat Source Required: You will need a heat gun or a similar heat source to properly use these connectors, which might be inconvenient in some situations.Overall, the YNZDRWA Solder Seal Wire Connectors Kit is a useful addition for quick electrical repairs, especially in water-prone areas. However, care must be taken to ensure a solid connection and avoid over-heating the wires during installation.
