Flaring the end of a tube is a process typically used to form a liquid tight, airtight connection at the end of a tube. There are two ways to accomplish a flared tube end. Rotary, or spinning the flared end, or ram forming. This fabrication method offers a long lasting seal that matches the exact shape of matching fittings such as J.I.C. nuts and sleeves. The single flare is available in both 37 degrees and 45 degrees and meets MIL spec #33584 and SAE specifications.
Double Lap Flaring
Double Lap Flaring offers additional strength for tube ends that are subjected to more stress and fatigue. The joint is designed so that the inside surface of the flare has a larger diameter so it does not interfere with flow characteristics of the system. Double lap flaring can be formed in the same shapes and meets the same specifications as the Single Flare.
