haisstronica 380PCS Marine Grade Heat Shrink Wire Connectors Set, 22-10 AWG Electrical Wire Connectors Kit,Ring Fork Butt Splice(3Color/12Size),with 9" Crimping Tools and Organizer

I have been wanting a kit of connectors that have decent quality shrink wrap.This thought came to me while looking at the price of packs of 10 or so of another brand that is good quality and commonly found at Big Box and Hardware stores.The problem is they are just too expensive.Sure, I could have bought inexpensive connectors at the local HB, but these have just a plastic shroud: it is not shrink wrap.I spotted these connector in a YouTube video, and the presenter said that was all they used.So I bought this kit. The shrink wrap is good quality - it shrinks down tight on the wire, and the kit even came with a crimper.The price is very good. A the local big box, a box of 15 GB insulated terminals is $4.91 - 0.33 per terminal.This kit with 380 pieces worked out to 0.17 per piece, which is just about 50% of the price per unit when purchased 15 at a time.Plus, the crimper is a bonus.

Crimpers work great and the connectors are great! Fast shipping

These connectors and the tool are very well made and work very well. I do auto, general electrical projects (machines, electronics) and marine electronics. The materials used are excellent - copper base that is tinned. Great adhesion and sealing for the insulation, and I love the ratchet tool.For marine applications, it is great that the core material is copper, which is tinned, and great that they seal well. And the butt connectors are welded (no gap in the barrel).But the end connectors are not welded /brazed. The premium end connectors like ANCOR have brazed barrels on the end connectors. More expensive, but better. Also, the circle connectors are ABYC compliant for boats, but the fork connectors are not. They should have a bent hook at the end of the fork. You can do that with some pliers, but it would likely crack the plating. Not huge, but think about it for marine use. In case of an electrical fire on a boat, the insurance company will likely look at ABYC compliance.Again, these are excellent products at a great price, but be careful using them for marine applications. The vast majority of issues in marine electronics happen at the connectors. Great that they are copper, but hooked fork connectors are essential for ABYC compliance, and brazed barrels are a good idea (not sure it is required). You could probably bend the tips of the fork connectors and you'd be OK..That said, based on my 5-star rating, I would definitely buy them again. Great product.

The connectors and crimping tool are meeting my requirements on a recently purchased boat that had to be rewired...

I've been undertaking some vehicle wiring projects lately, adding some lighting to my Overlanding rig, as well as adding a second battery. I had some miscellaneous wiring tools before, but this kit changed my game! The crimpers feel robust and solidly built. They are labelled well and it's very easy to know which set of crimping notches to use for whatever size (gauge) wire and connectors you're using. The heat shrink part really forms a good seal around the wire (I used it with a heat gun, rather than a torch).Overall, I am very pleased with this purchase and it's made my wiring project much easier! If I didn't have this product, I'm sure all the connections that I made and all the wires I had to splice would have been quite frustrating, since before I didn't really have the proper tools for it.This product also comes with a generous amount of butt-connectors and terminal ends. My ***ONLY*** issue is that I did have to drill out one of the round terminal connections because it wasn't large enough for my application. Perhaps some larger sized connectors would be nice, but otherwise, it's great. Still 5 stars. If I had to knock this product for this issue, I'd have to give it a 99 / 100. Happy wiring, everyone.

Worked got what we needed

I really appreciate the ratcheting feature of the crimps

Great product. Had to fix some wiring on my utility trailer and used this handy product. Everything right there to crimp the wires together. Used a heat gun to melt the insulation and it created a watertight fit. The case and crimped are solid. This will be used MANY times in the future.

I've only used this kit on one job so far... butt splices, eye splices, and spade splices, both blue and yellow connectors. So far, I'm very impressed, with both the connectors and the crimp tool...

Very good set
