A swivel body for a packing house washer which includes a hollow housing, a ball joint mounted on a water line coupler which is mounted into the hollow swivel body. The waterline coupler has a hollow neck which is in fluid communication with the swivel body chamber. Water is forced into the swivel body chamber and passes through the waterline coupler into a spray bar. The ball joint fastened to the coupler and neck allows the waterline coupler to articulate within the swivel body. When animal carcasses forcibly contact the sprayer bar, the movement afforded by the ball joint diminishes the likelihood of damage to the sprayer bar or any part of the swivel body. Bushings are used for water tight fitting of the ball joint within the housing. This device is easy to disassemble and repair and has a substantially longer life span than known devices.
