  • Crimp sleeve for flexible tubing
    Patent number: 8123257
    Abstract: A crimp sleeve includes a cylindrical side wall having a plurality of slots cut therein to form a plurality of fingers. Each finger includes a shank and an inwardly extending tab. The shanks of the fingers are formed at an inward angle relative to the sleeve wall. The tips of the tabs define a tip diameter which forms an interference fit with the nipple on which the sleeve is to be installed. The interference fit between the tabs and the nipple allows the sleeve to be pre-loaded on the nipple. When the end of a length of tubing is inserted in the sleeve, the tubing will contact the shanks of the fingers and urge the fingers outwardly, increasing the tip diameter.
