Lee Precision 44 Special / 44 Magnum replacement crimp sleeve SU3143

Lee Precision Crimp Sleeve 44 Special / 44 Magnum

The crimp sleeve is the internal sleeve that physically performs the case mouth closure in Lee Precision Factory Crimp Dies. Under pressure from the knurled adjustment screw, the sleeve contracts around the case mouth and applies a uniform crimp around the entire circumference, independent of the length of the individual case. This replacement part allows you to restore efficiency to a die whose sleeve is worn, scratched, or damaged, without replacing the entire die.

The sleeve is specific to the 44 Special and 44 Magnum calibers and must be installed in the correct orientation: the larger diameter end must face upwards, towards the knurled adjustment screw. If installed backwards, the crimp will be irregular or not achieved at all. It is the first component to check when a crimping die that has been in use for a long time stops providing a consistent closure.

This sleeve is the intended replacement for the Carbide Factory Crimp Die and for the die sets in the same caliber family: the Carbide Factory Crimp Die 44 Special / 44 Magnum (Lee code 90863) and the 4 Die Set 44 Special Carbide (Lee code 90966).
