ABSTRACT:
A hand operated swager for attaching a fitting to a hose includes a housing having a turning means rotatably mounted at the top portion thereof and a die for radially contracting the fitting onto the hose is removably mounted at the lower portion of the housing. The turning means is fixed against axial movement on the housing, is manually rotatable by the use of a wrench, and includes a ball nut threadably engaged with a pusher assembly that is axially but not rotatably movable relative to the housing whereby rotation of the turning means causes the pusher assembly to move axially into engagement with the fitting but imparts no rotary force to the pusher assembly that might be transmitted to the fitting. The swager also includes spring retainers for removably retaining the die in the housing.
