Our EPDM rubber orings are custom made for us. This is a sample size that is only available in black.

For Chainmaille: Closest in size to 18g 7/32" jump rings.  This ring is large but very skinny.  Use in projects where the O-Ring is either folded in half or doubled.  This O-Ring provides a very high AR to work with.

For leather: These can also be used with leather on larger cord sizes of 6.5mm or larger.  The skinny O-Rings will do well with 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.
