18g - 1” Spare O-rings - Black - Qty 100
Do you have the tendency to lose the O-rings from your jewelry? When you purchase our bag of 100 O-rings, you will never have to worry about that again. The O-rings are made of black nitrile rubber. These rings are available in various sizes, from 18g (1.0mm) through 1" (25mm). If you are looking for larger gauge O-rings, view the Spare Black O-Rings from 28mm up to 48mm here. The rings tend to run larger, so it is suggested that a size smaller be ordered to ensure proper fit. Rings are sold by bags of 100.
Please Note: These O-rings should never be autoclaved to prevent melting.
