We utilize Wirefy heat shrink in our work. It's a great product.


Good quality handy set to keep in your shop

Great crimper if you are really strong.

Crimper works great, but I cannot complete the crimp even with two hands. The only way I can get the tool to release is by putting the handles in a large vise to complete the crimp.

Order was messed up

So ordered 2 items after paying for the order there was a third item added notified company immediately but company sent and charged me for the extra order anyway and because of this yeah they refunded my me for the extra order but it cost $17.05 to send it back as of this date they I have not refunded the $17.05 shipping charge and I have notified the company of this I’ll keep you posted customer service should of caught this mistake immediately but chose to send it anyway very poor customer service!!

Frustrating to say the least.

I love the wirefy crimper and dies. I originally ordered the five piece set, which is great, but I later needed additional dies, and when I went to order them, I learned they cannot be purchased individually. They can only be purchased with the eleven piece set. The dies that can’t be purchased individual are the A2 (insulated quick connects) and A6 (large insulated flag terminals)). As far as I am aware all the other dies CAN be purchased individually. I contacted Wirefy and inquired about this. Answer was they don’t sale these ones individually, no explanation as to why. To me, that makes no sense…… asinine! They said I could order the eleven piece kit to get those two dies, but why would I, when I already have the crimper and dies. I could’ve ordered the eleven piece set had I.known about this issue. I would have given five stars if all dies where available for individual purchese.

Great products.

Just started with a need for uninsulated butt connectors. Ended up ordering terminal ends and shrink tubing. Can not wait to use.

Solder seal wire connectors

Great product won’t go back to but splice connectors


Best crimper I've ever used. Period.

Best wire terminals ever!

These are my new go to for wire terminals, the heat shrink works incredibly well and I love that you can see it actually adhering to the wire. Very good quality!

Die C not good for weather pack open barrel terminals

Overall the tool is great. (I got the 8-piece set.) But on weather pack open barrel terminals, the "C" die crimps the seal too tight. Probably works fine for regular open-barrel terminals, but for the weather pack style I had better results with an Iwiss IWS-1324b, doing separate crimps for the wire and the seal.

Also: I had to order an A1 die separately. Since Wirefy sells lots of heat shrink butt connectors, it seems like that one should be part of the kit.

Crimping Tool Set 11 PCS with Interchangeable Dies and Wire Stripping Tool

Great price and great service and great product

Best connections

Great product, great price

Quality connectors

Good quality, only drawback is the heat shrink shield will not seal to the smaller gauges (< 18g) of wire. Is close but does not adhere as it will on larger gauge wire.

Clean wiring repair

Outstanding quality! Do yourself a favor and purchase the heat shrink tubing to go along with the butt connectors.

Heat Shrink tube

Works very well, shrinks down as indicated on the website. Definitely worth the money if you want custom length coverings on your cables.

Great product. On time early delivery. Thanks yall.
