I’m assuming you’re teflon taping your various threaded connections. Mistakes I’ve seen on robots and professionally:
- Tubing cut crooked with wire cutters.
- 5+ wraps of teflon, 2-3 is enough.
- Bad, damaged, or poorly seated o-rings + gaskets.
- Missing blank plate on manifold replaced with blue tape. No, I don’t know why.
- Loose anything/everything.
- OVER tightened fittings, causing cracks or deformations. Decently snug is about right. If you’re straining/risking a hernia, it’s definitely too tight.
Our usual standard was less than 5psi drop overnight and pneumatics wasn’t done till they could hit that.
