Solid Connectors

Perfect marine grade connectors for rewiring my 1999 Ranger.

Excellent product and service.

The shrink wrap tubing from Wirefy is great, never have any issues no matter the diameter of the tubing. Ordering from them was just as easy and fast if not faster than ordering from Amazon. Will actually be heading back to Wirefy's website now to order more from them. Highly recommend dealing with them.

Best multi die set crimper

I am so happy with the crimper making my job easier when crimping different wire connection. It's all in one tool, easy changing dies for my crimping needs. Recommend the 11 pcs kit and add a variety of connector kits. Nice rugged box to keep all together in one place and has compartment to add to the collection of dies. if you have questions, they get back promptly. Very happy with the purchase.

Wirefy Works Great

The 'Heat Shrink Fork Connectors' are excellent. Used other brands and by far Wirefy connectors are the best quality and there performance is unmatched. Also, I highly recommend purchasing the Wirefy 11 pcs Crimping Tool Kit. It includes everything you need to accomplish all the variety of terminals and connector on the market. Never had any issue with the tool and connectors during or after the attachment process is completed.

Does the job

Top quality connectors with the heat shrink makes the connection weather proof and more secure!

Wire Crimper Tool

Great tool crimps the wire tight every time for a good connection. I recommend this tool.

Heat shrink butt connectors

These are the best butt connectors I have ever used
Ready to get rid of all the other connectors that I have!


Ordered heat shrink from Wirefy order shipped the same day arrived as scheduled no issues. The heat shrink was exactly what I ordered no substitutions, works great for our manufacturing applications, and was the best price I could find anywhere. No worries about ordering from them again.


I'd buy it again.

Did not work

Solder connectors were terrible and didn't work!

This order came quickly and were just what I wanted. Thanks.

Good assortment and price

Higher quality, quick delivery

Nice to upgrade my crumpets with a full set that is easily upgraded by adding individual dies later on.

No instructions anywhere

How the hell do you use the adjustable compression wheel? No instructions in the package or on this website.

Fork connectors

Super connectors and it hold wire very secure.

Wirefy crimping tool and dies

I was very impressed with the technical support I got on what die to use for certain application. Also I have been impressed with the tool itself.

Work perfectly and I've used almost all of them. Lots of wire repair I guess
