## Questions & Answers

**Q: How will the bulkhead connector hold up to alcohol based fluids like ethanol?**
A: I don't know, but doesn't the alcohol come in a plastic bottle?

**Q: Are the nuts and screws that come with this stainless steel?**
A: No

**Q: Will these work for a 12v 30amp application? i see a qc rating of 500v/ 30a but not sure how this translates to dc.**
A: I would say so, since I am connected and draw about 25A at 12 volts without any heat being developed. Just use a wire rated for more than 30A

**Q: How can you solder to the back of the male part you cannot reach it?**
A: Twist the plug shell, then put the shell into the cable and solder the cable, and finally twist it back to install the shell
