It's very frustrating that 99% of the hose adapters sold on Amazon are 1/8 or 1/4 threads and almost all of those adapters sold on Revain are 3/8 threads or larger. I can't find the one I want and ended up buying the wrong one because the hole size wasn't properly advertised on the host adapter I bought. I ended up using a tap and a set of dies to drill a larger hole, which worked better anyway because these temperature sensors require the thread to be grounded when the temperature activates the switching mechanism to ground it. Hose adapters are sold with an anodized color that prevents the bottom from working properly.
