Our EPDM Rubber Orings are custom made for us.  We have spent years developing this line of colors appropriate for your industrial or jewelry making needs.

For Chainmaille: Works most often with 16g 5/16" jump rings or as a replacement for them in closed ring form.  The thickness and slight size difference of this oring usually compensates for the lower AR that should be used when replacing jump rings with EPDM rubber orings.  

For leather: This size fits Regaliz leather (10x6.5mm oval leather cord).  It is most often used to hold sliders and other design elements in place.

Other uses: These are often 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.
