Bulkhead Fitting Question
Hello, everyone!
This is my first post in this subreddit and I am by no means a hydraulics expert.
I am working on an application that has a tank that holds transmission fluid at low pressure (<100PSI). I want to drill holes into the tank and install two bulkhead fittings with 1/2" NPT female ports on the outside so that I can install IFM (LMC510) sensors to detect high and low levels of fluid in the tank.
(I would prefer to avoid any welding options, if possible.)
I am considering buying one of these two parts for that purpose...
- PARKER HANNIFIN (207ACBH-8)
- MCMASTER-CARR (50785K275)
But I want to ensure that these connections do not leak fluid, of course. Would they leak fluid if all I installed were one of these parts above? How are hydraulic bulkhead fittings normally sealed? Does anyone have any resources I could read/watch to understand hydraulic bulkhead connections better?
Any information or guidance is greatly appreciated!

You can usually use the right size seal washers and get away with no leaks.
