The YELLOW JACKET 41300 is a Ritchie O-Ring Kit designed for servicing vacuum pumps used in HVAC refrigeration systems. O-ring kits like this one provide the replacement seals needed to restore proper vacuum integrity after routine maintenance or following a leak event. Licensed HVAC technicians install this kit during scheduled pump rebuilds or when worn seals cause vacuum performance to degrade. Keeping a service kit on hand reduces downtime during seasonal refrigerant recovery and evacuation work.
This kit is suited for use in commercial and residential HVAC applications where vacuum pump maintenance is part of routine system service. It is intended for technicians performing evacuation procedures before refrigerant charging on split systems, package units, and other refrigeration equipment. The kit supports proper pump rebuild practice by supplying the necessary O-ring seals in a single package.
Designed as an OEM-style service replacement kit for YELLOW JACKET Ritchie vacuum pumps. Consult YELLOW JACKET documentation to confirm fitment with your specific pump model before installation.
Installation should be performed by a licensed HVAC technician familiar with vacuum pump service procedures. Power down and disconnect the vacuum pump from all electrical sources before disassembly. Follow the pump manufacturer's service manual for proper O-ring seat cleaning, lubrication, and reassembly sequence. Do not reinstall the pump into service until a vacuum decay test confirms seal integrity.
