They all have the tubes - if there is water in your tank, it will not come at you at 140 psi, or if there is other shit, it will not come at you going down head first, unless there is a whole lot of it. If your dive rite came without tubes, check the package again, they do not ship the tubes screwed in, you have to do that, and use a pair of channel locks to tighten them. If you take them off, you can check for water without taking the valve off. Since it is a better idea to take off the valve and look now and then, and since this can be done with no tools at all, use the pipettes, it may save you from a mouthfull, especially if you get air from Strokepost. In fact, you may want to get the deluxe long ones for that local, and an oil filter, and be sure to wear rubber gloves when kitting up. - g Egil Aabel Naesguthe wrote: > > Every one agrees that the Dive Rite, Scuba Pro and Sea Elite (I have not > seen these myself) valves are equivalent, but why do only the Scuba Pro > valves have the thin tube sticking down inside the tank below the threads? > What is it supposed to do?

It can't be that critical if Dive Rite omits these tubes. > > Egil. > > ==================================================================== > Egil Aabel Naesguthe > > Queen's University E-mail: egil@me*.qu*.ca* > Dept. of Mechanical Engineering > Kingston, ON Phone: +1 613-545 6730 > K7L 3N6 > Canada Fax: +1 613-545 6489 > ==================================================================== -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
