The YELLOW JACKET 63340 is a ratchet bar and catch bolt replacement component designed for use with YELLOW JACKET tube bender kits. This part provides the mechanical engagement that allows the ratchet mechanism to advance tubing through controlled bends without slipping or skipping. It is a service replacement intended for HVAC and refrigeration technicians who maintain or repair tube bending equipment in the field or shop. Rugged construction supports repeated use under the mechanical stress typical of copper and aluminum tube bending work.
This component is suited for HVAC installers and refrigeration technicians who use YELLOW JACKET tube bender kits as part of routine line set fabrication or service work. It is appropriate for both residential and light commercial applications where field-bent tubing is required. Having this replacement part on hand reduces downtime when ratchet components show wear or damage.
Compatible with YELLOW JACKET tube bender kit models 63325 and 63331.
Installation of this replacement part should be performed by a qualified HVAC or refrigeration technician familiar with tube bending equipment. Ensure the tube bender is fully unloaded and free of tubing before disassembling the ratchet mechanism. Inspect surrounding components for wear before installing the new bar and bolt. Follow the manufacturer's assembly sequence to confirm proper engagement before returning the tool to service.
