The CDVALVECDVCD3800 C&DV-CD3800 is a valve core service kit designed for HVAC and refrigeration technicians who need a compact, organized solution for valve core storage and installation. The kit includes a plastic storage container sized to hold valve cores, a dual-function core wrench for installing and removing valve cores, and a thread chaser for cleaning and restoring valve port threads in the field. Six valve cores are included, making this a ready-to-use kit straight out of the package. It is well suited for service vans and toolboxes where quick access to valve core components is needed during refrigerant system service.
This kit is intended for use during routine refrigerant system maintenance, leak repair, and valve core replacement on Schrader-type service ports found on air conditioning, refrigeration, and heat pump equipment. It is appropriate for residential and light commercial HVAC work where valve core service is a standard part of the repair workflow. The included thread chaser helps address damaged or contaminated valve port threads that can cause improper seating and refrigerant loss.
Designed for use with standard Schrader-type valve core service ports commonly found on residential and light commercial HVAC, refrigeration, and heat pump systems.
Valve core service should be performed by a licensed HVAC technician following applicable EPA Section 608 refrigerant handling regulations. Recover or isolate refrigerant pressure before removing a valve core to prevent refrigerant release and personal injury. Use the included thread chaser on the valve port before installing a new core to ensure a proper seat and leak-free seal. Verify core seating with a leak detector after service is complete.
