While the list seems to like to bash stuff -- its evident from many of the
posts that heresay takes precedent over facts -- so here are some facts
regarding my oms manifolds 

One uses an OMS manifold with captured o-ring on OMS tanks with OMS tank
bands. You torque the valve in place, you adjust the bands for the right
height all on a flat level surface -- you then tighten the cross bar
section and then lock down the bands. 

It does not take rocket science to do this --- guess what ? They stay fine
-- I have been using OMS manifolds on 8 sets of tanks since the first batch
came to states. Not a SINGLE Failure. They have been dropped, banged,
stacked, tossed into trucks, slid across a boat deck in the middle of the
Atlantic, been to the WilkesBare, Doria, Republic, Monitor and a few other
places ...  

Here is the key to using most anything.  Use all the correct parts. You
must use the 8" bands for the 8 inch tanks, the 6.9-7.5 for the 6.9-7.25
tanks -- there is a welded spacer on the bands to keep them from key
stoning -- if you use a different band they dont work -- just like if you
use the wrong band on any manifold 

A few pointers and this applies to ALL tank sets 

on the tank bands --- the bolt that you mount the back plate to --- set the
depth of that bolt -- then double nut the rod to the band -- 

Aircraft Nut - flat washer BAND lock washer Nut ---------BAND lock washer NUT 

this will keep the rod from spinning when you lock the bands in place --- 

after a long drive or a few days on a boat -- put a ratchet to the bands
the vibrations will sometimes loosen the nuts --- 

cant have your nuts loose ya know .....

btw -- i also have diverite and Sherwood manifolds -- they all work fine
