How I Choose the Right Size
One thing I never skip is matching the connector to the wire size. If the connector is too large, my connection may be weak. If it is too small, the wire may not fit properly. I usually check the wire gauge printed on the package and compare it to the wire I’m working with. This saves me time and helps me avoid redoing the job.
My Preference for Quality and Durability
I always lean toward connectors that feel sturdy and well-made. A good connector should shrink evenly, seal tightly, and hold the solder securely once heated.

- Heat evenly until the solder melts and the tubing shrinks
- Let the connector cool before moving the wire

If a connector costs a little more but gives me a stronger seal and better connection, I consider that better value.
