Our EPDM rubber orings are custom made for us. We have spent years developing this color selection for all you industrial, craft and jewelry making needs.
For Chainmaille: This size is an exact match to the 18g 3/16" Jump Ring. With only a thickness of 1.2mm, this size works best in weaves where the O-Rings in each row will be doubled. Examples would be Full Persian or Helm Weave.
For leather: These can also be used with leather on 6mm cord and even with 6mm multi cotton cord. They will conform to a flat surface well because they are skinny but are a bit too large for 5mm flat leather.
Other uses: These are also used as stitch markers for Knitting & Crochet and can also be used for Macrame. EPDM O-Rings were developed to form a waterproof seal. They can be used with LED lights to form a waterproof seal between the bulb and hardware. Other applications may include body piercings, tattoo equipment, paint guns, bicycle & Industrial parts, or bottle seals.
Sizing: The ID or Inner Diameter is the size of the hole. Generally, choose an inner diameter slightly smaller than you require. The rubber will stretch to fit over items and form a strong seal or hold items in place.
