Great assortment of solid brass and metal O ring hardware for bag making, leather crafters, repair, and clothing designs. O rings are a popular style choice to accompany leather straps, grommets, chain and other ring hardware. You will find a variety of sizes and color options within our collection to make it easy to find the perfect style of O ring for your designs. We have three different styles that include welded, cast and split. Each style has a purpose in designs, A cast o ring gives a unifying look and is very durable because it was molded as 1 unit. Split O Rings are not solid all the way around, and have a "slit" in the metal. Welded O Rings are similar to split rings but were "welded" together."
