Why there are two widths
The glass tubes have a length tolerance. To alleviate these tolerances in production, Watercool fits O-rings of two different widths, 4 mm and 5 mm, and they can occur in any combination in your reservoir. This set contains both strengths.
When replacing them, you have to note which widths you found when disassembling the reservoir, and make sure to use that same combination again. Where two different widths were used, it is irrelevant which one was mounted where. It's just important that the combination is correct.
Changing the seals
The tube comes out after the top is removed: open the lid, undo the four M4x12 screws under it and pull the tube out upward. Set the new rings in place carefully so they are not damaged. More seals are in our O-rings category, and the tube itself is a spare part too, for example the Glass Tube 150mm.
Notes
- Drain the reservoir and take it out of the loop before any change to it.
- Check all seals before the first start-up. If an O-ring is squeezed or damaged, the reservoir must not be used.
