## Questions & Answers

**Q: why do you crimp the connector 3x?  One for each wire, what is the 3rd?**
A: I’m not sure why you have to crimp 3x’s unless their tool is designed that way? I only crimped  twice in my engine compartment of my pickup and have had no issues.

**Q: Will these work for 10/2 wire at 230V and 20 amps?**
A: You should be able to use on 230 volt 20 amp.  The yellow should handle 30 amp minimum. Usually if the wires fit in it. It will work

**Q: Do you have the Butt connectors that are 12-10 on one end and 16-14 on the other**
A: No, they are the same on each end. The colors indicate the size, as well they are labeled.

**Q: Can these be submerged? I want to use them for a bilge pump.**
A: Yes you can, the discription of the product says they are Marine Grade Waterproof Wire Connectors.

### ⭐⭐⭐⭐⭐ Works great

### ⭐⭐⭐⭐⭐ Buy These and the matching Crimp tool from Hassitronica!
*by P***O on September 13, 2025*

These are fantastic crimps. Buy the hassitronica crimp tool. Bought some ring terminal crimps from another brand and they included some butt crimps. All of them were low quality, weak crimps that didnt hold. These crimp solidly and the shrink wrap really holds the wire in place. I havent measured ohms across them but they seem to make solid connections. I am using them on an aem twin fire cdi igntion system which draws lots of power without issue as well as every other connection on my project car. Great value, will purchase again once I run out as I am on my second set already.
