Assembling doubles with oms manifold

[Rooster1]

I will later this week be assembling an oms isolation manifold on twin 80's. I think the oms manifold is assembled on doubles a liitle different then other manifolds. Anyone here ever do an oms manifold and doubles set up??

But this is a pretty good resource...

UH, yeah, dude... WHy do you think its different??? They are much easier to set up than others with barrel style center piece... Just put both valves in the two cylinders, leaving the center piece separate. Then start the center piece on both tanks, and snug the threads up. Then put the bands on. Tighten bolts on bands when tanks are laying down to assure tanks being in the same plane when tightened. Make sure the center piece is tight. Otherwise, it may leak. Good Luck. Its not that tough...
Just remember one thing: righty tighty, lefty loosy.

The boots on my tanks screwed up the alignent a bit, perfect excuse to dump the boots Other than that i see no difference.

This reminds me: take the boots OFF before you assemble the cylinders...

Thanks. The reason I ask is because I know the oms manifold can acommodate 6.9-8" tanks and since oms uses the "captured oring system" I wasn't sure if the inside of the isolator would have to be adjusted so that the oring on each valve sits snug against the isolator because I would think the difference between the 6.9" to 8 " diameter in tank will change the distance in the isolator connection and might change how the oring sits against the isolator

Diameter on the cylinder may change, but manifold does not change in any way. Thats why bands are so important. The distance between the cylinders will be determined by the manifold, and then the bands are specific to the cylinder and manifold to hold them both together correctly...

No adjustment needed on the OMS manifold...


GOod Luck...

Thanks a million. I had put them on yesterday and couldn't believe how easy it was to do the oms. I don't think there is an easier manifold to set up

well thermo is a bizach, i can tell you that. if i ever get them back together i swear i'll never take them apart again
