Where to find heat shrink with solder (solder seal connectors) for wires lighter than AWG 26?

[parkerchip]

The smallest variety (white) in these things are intended to connect wires between AWG 24 and AWG 26.

Sometimes, I need to connect wires from AWG 28 to AWG 32. Is there a smaller solder seal connector on the market?

Any recommendations are welcome!

Make a Western Union splice and cover it with adhesive heatshrink.

I recall we used rubber grommet hose for strain relief on twisted solid AWG 30. But my guess you could use liquid rubber or nail polish , Brushed on, then wax string tie wraps. Strain relief is essential.
