I’m using Loctite 567, rated for gasoline and oils to 400 degrees, intended for coarse threads like NPT. It contains Teflon and will set up but not harden so parts can be disassembled if needed. Specs can be found on www.useloctite.com .

My IA taught me that the sealant should be applied so the first one or two threads stay clean. This helps keep any excess from getting into the system and possibly clogging filters or screens. He also told me not to use Teflon tape- fragments can get into the affected system and they have the potential to block small passages, contaminate bearings, etc. -Bill Wade

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.
