For Chainmaille: Works most often with 20 gauge jump rings . The thickness of this oring usually compensates for the lower AR that should be used when replacing jump rings with EPDM rubber orings. Works great for European 4 in 1, Japanese & Dodecahedron patterns.
For leather: This size fits 2mm, 3mm and flat 3mm leather cord.
Other uses: These work really well as spacers to protect strung beads. These are also used as stitch markers for Knitting & Crochet and can also be used for Macrame. EPDM Orings were developed to form a waterproof seal. They can be used with LED lights to form a waterproof seal between the bulb and hardware. These have also been used for body piercings that often require a stopper of this sort, tattoo equipment, paint guns, bicycle & Industrial parts.
Sizing: The ID or Inner Diameter is the size of the hole. Generally, choose an inner diamter slightly smaller than you require. The rubber will stretch to fit over items and form a strong seal or hold items in place.
