Default Flex Replacement Lines

Tom,
I would certainly be interested!
Could you work up some estimates assuming various sales levels using -2 and -3?
Sounds like a potential improvement in safety and maybe a greater margin before air bubbles in the lines!
Cheers

Well, we broke out the drawings and made a few minor tweeks. Lookiing at feasiblilty. The injector side is the hardest, because it needs the -2 ball seat ends, like AN800. Not that big a deal other than you need a 90* and that gets alittle tricky. The flow divider side could be AN800, OR AN flare, and change the nipples to AN816-2 Steel. Just as easy to keep it the way it is, and use AN800 on both sides of the hose.

Only big issue I see is the variations of hose end angles to connect at the flow divider. Because this is experimental, flow divider configurations are all over the place. BUT---can it be done? Yep.

I sent Steve a sample of what I wanted so he could machine 1 or 2 on the HAAS. Stay tuned.

Tom

Probably a long shot and might make the assembly too tall, but what about creating an AN800 male seat to AN2 male flare adapter for the nozzle? Then standard AN-2 hose ends could be used.

HI Lars----needs to be a 90*, and in all proablity something brazed like the pic below. Problem is capturing the nut, and its a brass 5/16-32 nut, and it would be hard to do, and defeat the purpose of a strong, billet, unbrazed fitting.

But, I may look into it to see.

OH---the fitting in the post above is NOT brazed, it has a pinned(wired) on nut, and there just isnt room on a primer nut. AND expensive to do.

I was actually thinking a straight adapter with a 90 on the hose, but that is probably too tall.

Regardless, I was eyeing my own injector lines suspiciously a couple of days ago. Add my name to the customer list if you come up with a solution, Tom.
