All, am having some issues with a double threaded bulkhead micro leaking. When I first installed it I had no issues for 5 years but on re install it does not leak from the bulk head area but from the threads where the hose barb elbow threads in. I seem to have over tightened the fitting and split the bulkhead most likely because I used dope instead of tape over lubricating it. Its currently outer wrapped in teflon tape so the drip runs down the length of the hose back into the sump area instead of dripping on my floor and I have a new bulkhead arriving tomorrow. The question is whats the rule of thumb for tightening these types of fittings. Seems like you can get them pretty tight pretty easy splitting the bulk head, but not tight enough and they leak. Also, the outer bulkhead gasket in the pic is temporary, once I get the new bulkhead I will only be using the inner gasket.
