Wirefy heat shrink butt connector

Purchased these along with the wirefy ratcheting crimpers and their heat shrink tubing and I'm glad I did. Used in conjunction with one another these products offer, in my opinion, an extremely durable , incredibly secure wire connection. They don't do anything extra or special but they do what they're meant to do very well. No more worrying if my butt connections are going to pull apart, corrode, or fail. Crimps are uniform and tight, connectors shrink and seal for a watertight connection, and the heat shrink tubing is cut to a prefect size and seals over the connector very nicely as well. Very pleased with all these products. I used these to re-wire my semi truck's headlights and taillights. A head or taillight out can result in loss of revenue, time, and can often incur fines. With these wirefy products, I'm not at all concerned about any of that. 5 stars and they get my recommendation any day.

Works awesome, don’t know if you have a stripping tool that strips to correct length

Great Quality

I already used them to wire accessory lights on my truck, no disappointments, definitely better than cheap big box store connectors.

Heat shrink connectors

This is my second purchase from Wirefyshop. They have excellent products at a good price. I have been using these connectors on boat trailers and snowplows with excellent results. The shrink connections expel a small amount of glue/sealant which provides an excellent barrier for the connection. I have had no failures yet and really don’t expect any. I would highly recommend their products.
