Qibaok Heat Shrink Ring Connectors 300 PCS Insulated Electrical Crimp Heat Shrink Wire Connectors Marine Automotive Copper Ring Terminals Kit

I’ve been using these to crimp ring connectors onto 16 gauge tinned marine wire. I had 100% failure rate on doing a pull test. I’m using an Ancor brand crimper, so it’s not the crimpers problem. Since I didn’t have anything else available, I ended up using the 18 gauge crimp setting to get a tight connection. Also, the adhesive does not extend all the way over the barrel, allowing room for moisture inside the barrel. I would not recommend these where corrosion and vibration resistance are important.

Good product

I used them on my boat and golf cart and they all work great. Worth every penny and will order again.

I purchased butt connectors made by the same company and they seemed fine, but these ring connectors will not crimp securely. I tried half a dozen times and approached it from different angles and nothing made a solid connection that would not easily pull out. Some people gave these very high reviews, but there are a significant number of bad reviews. They must have a poor quality control process that allows for bad batches.*** UPDATE ***I'm changing my review from one star to four. I bought one of the Qibaok crimping tools and I can now get a good secure crimp. The cheap crimpers I have used for years just will not work with these connectors. Deducting one start because the heat shrink leaves a little bit of the wire exposed on the end towards the terminal, so these connections will not be water tight. Overall, not bad for the price.

Overall a good product for a relativity reasonable price. Did have a couple of pieces that the shrinking and sealing of the wire was not ideal and I had to redo over. Found one defective end but other than that they seem to work well. I still recommend these connectors.

These are what we used in control cabinets when T&B was low on stock due to Covid delays in production. They are worth the money but make sure you get a crimper meant for heat shrink style terms.

These are great for my dump truck great alternative as opposed to just using the tape this looks more professional

Works great for me.I added a photo of the tool I use.It punctures the heat shrink a little bit,but a dab of silicone works fine after shrinking it.

these work great with a good selection of sizes
