OK, let’s talk about “thread
sealants”. Usually pipe thread to pipe thread joints are lubricated by Teflon
paste or tape. You’ll notice I said lubricate not seal. The purpose of
the “sealant” is to lubricate the joint and prevent galling, not to
seal. NPT threads are tapered not straight. The taper is what provides the
seal.

Subject: [LML] Recoseal
I
recall the reference to Recoseal as well, but I could not find it in the manual
this afternoon.
For
Bruce's benefit, this was a thread sealant called out for the NPT pipe threads
on the AN fittings going into the hydraulic cylinders. There was no
suggestion that it be used on the flared fitting connection. Your
suggestion is correct -- if you can't get the flared fitting to seal, remake
the flare.
I used
Loctite 565 pipe thread sealant for screwing the fittings into the NPT holes in
the cylinders. Rated to 10,000 psi and can handle gasoline and hydraulic
fluid. Available in a lot of places, although I don't recall whether I
bought it at Home Depot or the local auto parts store.
