[AT] Fwd: Re: Hydraulic fitting

[Richard Fink Sr]

------

I know this is to late but i was taught with hyd. fittings place a
hammer on one side and hit the other has always worked for me. And yes
they do make left hand pipe threads and fittings don,t have taps and
dies but know where i can borrow them.

So I put a pipe wrench on it, and this time used  a 4' pipe (used 2' before) on the pipe wrench handle and put everything I had on it.   Still nothing. So I tried the other one. That one came loose. So I went back to the first one.  I basically had to lunge at it -  it finally broke free.
