Housing for resistor? (lemmy.world)

I have some metal film 1/2w 2.2ohm resistors in some car wiring. I'm concerned about the durability of this install and am seeking advice on how to protect the resistor once it's soldered in place. The obvious is heat shrink tubing, but it's there anything more substantial?

I'll be using these resistors in a custom pigtail that will plug into the car wiring. 3D printed housing? I have tried searching and I haven't found anything like that.

I would make sure the solder connection between wire and resistor is very solid, and then encase the stuff in heat shrink tubing with glue in it. (Adhesive Lined Heat Shrink Tubing)

If it's good enough for Nasa, it will work for your car: https://makezine.com/article/technology/computers-mobile/how-to-splice-wire-to-nasa-standards/
