Spare part or a new length
This tube is the spare part for a 100 mm reservoir. It also lets you convert a reservoir of the series to a different length. For that you need struts of the same length, which are sold separately: the 100mm struts come in black, raw aluminum, red and blue. The same tube in other lengths is the 150mm and the 200mm version.
Changing the tube
Open the lid with a quarter turn counterclockwise, undo the four M4x12 screws under it and lift off the top. The tube then pulls out to the top. Watch the O-rings while you do it so none gets lost. When the new tube goes in, check that the O-rings sit correctly and are not damaged.
Watercool uses O-rings of two strengths, 4 mm and 5 mm, to make up for the length tolerance of the glass tubes. Reuse the exact strength you found in your reservoir. Spare O-rings come as the O-Rings for Glass Tube kit.
Notes
- Drain the reservoir and take it out of the loop before any change, and check all seals before the first start-up.
