PETG
Every fitting we ship is printed in PETG. It's the right default for fittings: tough without being brittle, good chemical resistance, handles water and most coolants without swelling, and holds a thread. It bridges the gap between easy-printing PLA (which creeps under load and softens in a hot garage) and engineering filaments that cost more than the problem usually deserves.
Colors
| Color | Notes |
|---|---|
| Black | The workhorse. UV-stable, hides layer lines best. |
| Green | |
| Red | |
| Orange | High visibility. |
| Blue | |
| Clear | Translucent — handy when you want to see flow or fill level. |
| Purple | |
| White | |
| Yellow |
Pick the color in the configurator; it's part of the part spec and prints exactly as ordered.
Where PETG Is the Wrong Answer
We'd rather tell you now than after it fails. Skip printed PETG for: food contact and potable (drinking) water, since a printed part is not food safe, continuous service above roughly 140°F, pressurized air (stored energy in a plastic vessel is a safety problem, not a materials problem), fuel and aggressive solvents, and any structural part where failure hurts something. If you're not sure, describe the job in your quote request — a person reads every one.

Need something PETG can't do? Ask in your quote request. If a job genuinely calls for a different filament, we'll tell you whether we can run it — and tell you honestly if we can't.
