Bodul67 Posted February 17, 2021 Share Posted February 17, 2021 I have the AQUATEK Aquarium CO2 Regulator with Integrated COOL TOUCH Solenoid. It's on a timer to turn on & off at specific times. When the timer switches off, the solenoid sticks in the open position. I have to unplug & plug it back in multiple times before the solenoid closes. I unscrewed the solenoid from the brass regulator and found that the rubber O-Ring has been torn slightly and that's the reason the solenoid wouldn't close properly. I reached out to Aquatek about a replacement O-Ring and they replied by I need to order a new solenoid. Of course they would, they want me to pay $40 for a new solenoid rather than pay less than $1 for a new O-Ring. Horrible!!!Has anyone had this same problem and how was it rectified? I can't seem to find the exact O-ring to replace. I found one at Lowes and it's 5/16" ID x 1/16" CS, but it's too thick. The CS is half the thickness around 1/32" that I need.The picture below is the O-ring that I'm talking about. It's NOT a picture of the torn one that I have, it's just a reference to location of O-Ring. Link to comment Share on other sites More sharing options...
CT_ Posted February 17, 2021 Share Posted February 17, 2021 I don't think i've seen orings as thin as 1/32 in normal use. 1/16 is the smallest they usually come. could it be metric? 1x8 maybe? https://www.amazon.com/dp/B07F3J4RX5/ Link to comment Share on other sites More sharing options...
