Great quality and variety set

I am impressed by the variety and quality of this heat shrink butt connector set. It will save me time running around town trying to find connectors when I need them. The variety will cover just about any wiring connection situation for 10-22 gauge wire. The heat shrink feature adds security to connections and prevents moisture from attacking connections and promoting corrosion. I also purchased the 270 pcs connector set from Wirefy and was equally impressed with the quality and selection. I suggest investing in a good crimping tool such as a new ratcheting or hydraulic crimper which will simplify and ensure quality crimp connections.

The best deal and best heat-shrink butt-connectors you can buy!

My father bought these and recommended that I ditch my old crimps for my solar panel fix and use these great heat-sealed crimps. Used a Titan Crimper and they worked great. Loved having the assortment as I had different gauge wires to mend. My father and I are ditching our old butt-connectors and will ONLY use these moving forward. Heat-sealed great with our heat gun. Great products!

crimp and seal in one connector

I was very happy with the connectors there was a very good selection in one box yesterday I used them at a marina for landscape lighting they crimped very good and the heat seal was very .very good made a excellent connection each time

YES.....I like these Butt Connectors!

Yes....as a marine mechanic and boat owner, I'm happy with this product ! I use them mostly for boat trailers and other marine applications, and the "double wall" or " lined with glue" feature is absolutely ESSENTIAL !! If you heat (I use a Wagner HT400 heat gun, available on AMAZON) the heat shrink tubing, and you do NOT see glue oozing out the end....you better run ! ( For the garbage can !)

Having the right parts is everything

I am neck-deep in a project to straighten out my boat's wiring, and needed these connectors for several reasons (add new circuits, extend existing circuits to new switch/fuse panels, replace failing low-quality connectors). They performed as expected, especially when combined with the correct crimping tool (which I also recommend - see my review for https://www.amazon.com/gp/product/B07GFXHH91/ ). The crimp holds the wire tightly, and the adhesive-line shrink tube sealed the connection adequately.

The result is a super strong connection with very low risk of the wire ...

Wirefy connectors have significantly heavier gauge coated copper crimp barrels than the other vendors, and the shrink tube inside has a strong adhesive/sealant that seems to melt right into the wire insulation. They're translucent, so you can see the wire and where you're crimping, to confirm everything is in the right position before you squeeze. The result is a super strong connection with very low risk of the wire ever pulling out, a common event with lower quality crimps. These are all I will buy now. I just re-read this. I sound like a paid-off shill for Wirefy. I'm not. :) Wrote this to benefit other crimpers.

These work as well as the ones I pay 3x for ...

Nothing sexy about butt shrink connectors but these do a great job! the quality of the materials is really sturdy - no issue with tearing the insulation when using the correct crimping tool. I use a heat gun on high and have no issues with burning, the insulation - 5 stars - works as advertised and priced right... use a rubber band to hold the little plastic box shut...

Just what I needed

I got these for various projects that pop up around the house and shop from time to time. They seem to be of high quality and are packed in a plastic organizer tray. These are all that I will probably ever need. They bond to the wires after crimping by use of a heat gun (or lighter) and am adhesive seals the connection. Great for use in outdoor or marine environments.

Exactly what they are supposed to be

These are good heat-shrink butt connectors. Be aware that these are not the new type with the built in solder. These are only crimp butt connectors with heat shrink plastic around them. As long as you know what you are ordering, you will be very satisfied. I've used a few of these and they work fine.

Good packaging, high quality, great assortment.

Received the crimps fast, well packaged and more importantly the small compartment case is well constructed. Looks like something you can use for a while and not worry about the parts getting mixed up. These barrel crimps are better than previous crimps I've used as they have a longer shrink sleeve. I'm using them on a boat, primarily. The quality is high, the materials are good and the shrink ratio is great. I particular like the adhesive that provides a good seal Will def buy these again when needed
