    I have been searching the internet to no avail for a generic version of the items depicted below. It is a silicone type band with an integrated o-ring used as both a backup to the o-ring that holds a glove on the ring of a dryglove system, as well as provides protection and adornment to the edge of the glove stretched around the ring.

    These rings are used by various companies such as Waterproof and Fourth Element. I am looking for a generic source for these and am obviously not using the correct search term.

    Does anyone know what the correct nomenclature for these are and/or know of a non-dive industry source (wholesale or retail) for them?

    They're called cuff rings or drysuit glove rings.

    Thanks...though I am looking for the non-dive industry name for them so I can find an available, affordable source for a generic version of them.

    I doubt there is one. I think they are purpose built.

    Plausible....but I am hoping that there is an actual non-dive industry use/nomenclature for them.

    I have found P-Shaped gasket material is similar but cannot find a source that has it as rings in different diameters.

    I tend to think that companies like Fourth Element and Waterproof look in a product offering catalog for silicone products and choose the product that matches the profile they want and then they specify color and logo.

    Looking at the ones that come with the Fourth Element Ellipse dryglove system I am wondering if they are a "P" silicone extrusion that is then spliced and vulcanized into a ring.

    If it's something you can use, LP has Bare cuff rings for $17.95

    From the picture the Ultima rings are a molded part. I can't tell on the fourth element. Extruding and then bonding would leave a potential failure point along the axis that would be seeing the most force when the ring is stretched. Also the cutting to length and joining process would be expensive to control to within a reasonable tolerance. With a multi cavity mold there are no secondary operations required besides marking.

    I would guess that these are made for each manufacturer to interface with their system, I doubt they take a catalog ring and then design their whole system around it.

    I can't tell exactly what the cross section looks like but if you're looking for something similar I would start at McMaster Carr and look through their offerings for O-rings and Shaft Seals. A quick look shows a few things that might work.

    Thanks but if I am not mistaken, what LP is depicting/advertising is a rebranded si-tech PU ring for their round quick cuff system....the PU ring is the part glued into the suit sleeve.

    Probably but so what?

    You wanted a cuff ring, I showed you one - actually 2 for $18.

    Or you can pay $132 for the entire system from Fourth Element and throw most of it away.

    Good luck in your search.
