CHEZURAquarium decisions A seal works through correct shape and even compression. Dirt, twist, ageing and uneven latches create a water path.

Quick connectors contain their own internal seals and service requirements.
Dry, fill and observe static, then running. Tissue makes tiny droplets visible.
Keep critical spares but do not open only to replace a supple intact ring.
| Situation | What to do | Why |
|---|---|---|

| No exact spare | Do not improvise | Compatibility is critical |
After replace, measure or observe Ring flattened again with the same method. Record Any unexplained dampness is a leak. as well; if neither changes as expected, revisit the diagnosis before adding another intervention.
