Heat Shrink Bullet Connectors Full Insulated Electrical Crimp Wire Terminals Assortment Kit, Red Blue Yellow,100 Pack

Overall I am not sure if shrink tube terminals are a good practice although I loved the idea.Having used another brand I was looking for something better.I did not use these because the shrink tube appears to be smaller than the other brand and I already have experienced problems.This is a general view of the concept of this style of terminal1. Crimping the terminal using the expected crimp pliers can break through the shrink tube2. The shrink tube can creep back exposing the terminal3. Sometimes difficult to get a good crimp that will hole the wire where you have used the correct size. Crimping tighter can cut through the shrink tube.4. Bullets don't always grab tight when inserted one into anotherI believe that a nylon covering and then use shrink tube may be a better choice as the you are less likely to break through the protective covering.Qualifications for the review - 30+ years in the 12v industry including Car accessory installations.

I needed to replace connectors on the voltage regulator of my Mercury outboard. The original looks like it overheated because of a poor connection and melted. I got these hoping that they would be close to water tight for marine operation. They are not water tight or even resistant. After making the connection I used a water repellent grease on the outside to help keep out condensation.A couple months after making the repair with these I found that Mercury has its own OEM connectors. If I have problems with these LALA connectors I'll swap them for Mercury's.

Good product

Can’t complain. They were received quickly and work just fine.Note that the ad depicts yellow, blue, and pink connectors. I received blue, pink, and green connectors (see pic). Not a big deal but it makes me wonder about why there is a discrepancy between what is pictured and what was received. Is there a larger quality control issue lurking? I mean, these are electrical connectors... 😥The reasons why I rated them four star instead of five:1. There is no case / bag included that keeps these organized. They are shipped in a white bubble mailer and they once you open that, five clear baggies of connectors. I know I’m going to lose these. I’ll put them all in a clear zip lock bag but the finishing touch of a better organizational system would have been an exceptional touch.2. The blue and pink connectors are sent in separate baggies: one for the males, one for the females. Easy to find! But the green connectors are mixed in a single bag. Again, not a big deal, but enough to hold this back from a true five star rating.

I needed to connect wires in the hinge of my car door. These connectors enabled me to repair/reconnect a few broken wires at the break points without having to do a whole extra amount of work/effort to open up the door panel to access the ends.Simply stripped the wire at the break point, inserted the two leads into the F+M connectors, crimped, heated with a heat gun, connected the F+M bullet connectors together and voila the electric window went up and down again.Definitely going to keep a handful of these around.

Save your $. Get a butt connector instead. I wanted to use them to connect a car stereo. The whole point of a bullet connector was to allow you to connect/disconnect the wires from the radio. Bullet connecters are Male/Female that should snap/unsnap. However you cannot heat shrink the female end onto a lose wire and then later connect the male end. However, these ones have to be connected before you heat shrink them. That means are useless as bullet connecters. You might as well buy butt connecters to start with.

The metal is very fragile so you must be so careful or it'll break. The heat shrink on the female ends is a bit long, so once you shrink it, you must trim the excess off in order to get the male end in. Likely a case of you get what you pay for.
