The previous owner used 1/8NPT to AN fittings on the gate and now the gate leaks where the 2 actuator halves mate, but right by the fittings. Bill is suspecting that threading the NPT fittings in too tight could have caused a small crack which is now causing the leak. And as for using thread sealant on non tapered fittings, this came from my build thread on 8th:
Interesting. My thought process is that the sealant creates a 'seal' so no gas or liquid can escape. Don't see why it wouldn't work. I guess we'll see how it goes, one way to find out! If you want the washers to work, I would use crush washers vs regular washers. That would make a difference in my mind, but who knows. [MENTION=28]Spaz[/MENTION] [MENTION=56]Adm_rsx[/MENTION]
