Hi Carroll,
Thank you for your question. The outer diameter of the compression ring is 2.54 inches and the inner diameter of 1.89 inches. If this is not the size you need, please provide us with the model number from the air compressor that this is used on and we will be happy to check on the correct part for you. The model number will usually be on a label found on the tank. If you could resubmit your question with this information, we would be happy to help you. We look forward to hearing from you!
