Description
Made with certified recycled precious metal. Our silver, gold and platinum is refined from certified recycled content rather than newly mined ore, through refiners audited by outside parties.
How we source our metal
Sterling silver seamless hollow round tubing supplied in straight 12" (304.8 mm) lengths for hinge making, tube setting, and structural jewelry components. Smooth, continuous walls give a clean, bright edge around stones and along hinge knuckles.
Features
- Seamless hollow round tubing for precise hinge knuckles, tube settings, and other fabricated components.
- Supplied as straight 12" lengths, ready to cut into custom sections at the bench.
- Interior and exterior diameters coordinated to common wire gauges for use as hinge pins and rivets.
- Wall thickness options from light to extra heavy for decorative to structural applications.
- Exact factory dimensions listed by OD, ID, insert wire gauge, and wall type for accurate planning.
- Compatible with standard silver soldering, stone-setting, and forming techniques used in jewelry studios.

Notes
For hinge making: Select a wire diameter slightly smaller than the tubing inside diameter (ID) so the hinge pin turns freely without binding.
For tube-setting faceted stones:
- Choose a tubing OD approximately 0.5 mm larger than the stone and an ID smaller than the stone so it rests on a seat instead of falling through.
- Use a setting bur the same size as the stone; if the stone falls between bur sizes, choose tubing the next size smaller and expand it slightly with a center punch.
- This method produces a subtle taper in the setting that can be visually appealing and secure.
- Bezel setting tools such as Part #153.154MA can speed up and standardize tube settings.
Shorter 3" lengths of comparable sterling silver tubing are available separately under Part #844-1005MAIN.
