Power Beyond or HPCO valve help needed

[MtnViewRanch]

When taking fittings apart, which would you rather clean up before reassembly, paste or tape?

Neither one is difficult to clean up. The people that get in a hurry are the ones who forget.

I just took the Gesen V12 valve apart and built a power beyond adapter to fit it. I posted several photos and a dimensioned drawing in my photo album, Bobs Backhoe on this site. I will put it back together and test it in a few days if the weather holds out. Hopefully this will avoid the problems with too much pressure on the seals of any valve in the system.

The original adapter I built had a 1/4 NPT internal thread, but no standard hydraulic fittings are available to fit a 3/8 hose. A 3/8 NPT would work, but the wall thickness would be rather thin, so I changed the design and used a O-ring seal type fitting with a 9/16-18 thread. This will accomodate a standard 3/8 hydraulic fitting and provides a better seal with plenty of wall thickness, although it takes a little more machining. A PDF version of the drawing is attached.
