Rubber O-Rings Choose exactly what you need from Cock-a-Hoops selection of rubber o-rings. Made from quality, basic black Buna-N rubber, these rings do the job. Flexible, but not stretchy, they have just a bit of give. All rings have the same thickness - about 5mm (.21 inches). Available in your choice of 18 different sizes based on the inside diameter, from 3/4 inch (19mm) up to 2-1/4 inch (57mm). The sizes are "nominal", meaning that the actual inside diameter may be a tiny fraction less than the stated size. * By popular request, additional sizes have now been added: 2-3/8 inch and 2-1/2 inch. Choose the size(s) you need from the drop down box below the item title at page top. You will see that each ring has both standard and metric sizing. * Please note that you may also choose from ring sets (a set consists of several select rings, one of each size) at a considerable cost savings to you. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Cock-a-Hoops is your ring headquarters!
