Nitrile Rubber Cock Rings

NEW: Metrics – Now available in sizes from 16mm to 38mm. They are a bit thicker (6mm) than the standard rings, for a slightly bolder presence. The 1mm increment sizing allows you to find a precise fit for your head or shaft. Scroll down the drop down box to see the selection.

Choose from our huge selection of strong and durable Buna-Nitrile Rubber rings. They are non-stretchable, but very pliable and have just a bit of give. These rings have multiple applications:

Experimentation – Not certain of the exact size you need for a particular use? These rings are an easy and inexpensive way to experiment with different sizes before investing in a a metal cock ring. And they are indispensable if you are sizing yourself out for a custom chastity device.

Retainers – The smaller sizes can be worn in front of a heavy head or shaft ring to keep it from sliding off, as shown here:

Partitions – Use them as partitions between stacked metal rings to avoid clanging or skin pinching, or to add variation and color to your stack.

Our standard size rings are available in sizes from 7/16 inch up to 2-3/4 inch. They’re 3/16 inch (almost 5mm) thick and non-stretchable, but very pliable and have just a bit of give. All sizes are “nominal”, meaning that the actual inside diameter may be a fraction less than the stated size. The drop down list shows all the sizes, along with some money-saving sets (when available).
