Several isolation manifold isolators. If you're buying these hopefully you know what they are... this is the middle section of the isolation manifold with shut down valve. These are unserviced, untested, sold as is. Easy to rebuild for a few bucks or just toss the dice and dive with it! These are the universal thread and are all interchangeable... so if you've got a Thermo, Halcyon, Dive Rite, Sea Elite or other similar manifold, these will work. They won't work with older Genesis, OMS or likewise manifolds.
