Where did you source these 1" NPT to 1" liquid tight cord grip fittings at. I'm going to "steal" your idea, but going to put some ball valves in the middle and fittings on both ends so I can use half of it to heat my fresh salt water prior to water changes when needed. Will the heat from the heater not hurt the seals over time? Awesome job on the whole build. Thanks!
