    Will I ended up ordering my B-2MA2 with the 1/8 MNPT I should have it in a couple of weeks.
    It's looks like the SS-2MA2

    Swagelok

    It should work find with the JBJ Bubble Counter
    I just hope there is enough clearance from the Solenoid to fit the Bubble Counter with out any adopters?

    This was brought to view:

    1. Be certain valve is in the FULL OPEN position, and
    system pressure is relieved.
    2. Thread Jam Nut off Bonnet.
    3. Slide Locking Sleeve above Bonnet Hex.
    4. Using 5/8 in. wrench, tighten Bonnet to 25-30 in.-lb
    (2.8 - 3.4 N•m) to compress packing (TFE Guide Ring).
    5. Slide Locking Sleeve down over Bonnet Hex and Body
    Hex (Body Extension Hex on MG and MGD models).
    6. Tighten Jam Nut against Locking Sleeve.
    7. Test valve for proper operation.
    CAUTION: M Series valves are not designed for shut-off

    I assume that it comes close for shipping and we have to open it up and locking it down for operation ?
    I don't have a 5/8 tork wrench will finger tight and give it a tweak would be good enought for this?

    Will I got my B-2MA2 and WOW it looks like a tank compared to my Clippard Needle Valve ! Well I called my local Swagelok store ask the Representative about the little note that came with the needle valve about the packing adjustment. He explane to me that for our application of CO2 BPS we should not have to do this adjustment at all we are not using pressure of 1000 psig (69 bar. This what I got of line:

    Testing
    Every Swagelok S, M, and L series metering valve is factory tested
    with nitrogen at 1000 psig (69 bar). Shell testing is performed to a
    requirement of no detectable leakage with a liquid leak detector.
    Every Swagelok L series metering valve is tested for bubbletight
    seat shutoff at 100 psig (6.8 bar) differential pressure.

    He said that these needle valves are use for High Pressure application and after awhile they may get loose after awhile and these is just to reset it.
