CDV-CD3813 Brass Valve Core Tool Kit 3 Cores

Product Description

The CDV-CD3813 is a brass valve core tool and container kit designed for refrigerant service work on Schrader-type valve fittings. The kit includes three replacement valve cores alongside a compact, knurled-grip tool that allows technicians to remove and install valve cores without fully depressurizing the system. The knurled body provides secure hand torque in tight equipment spaces. This is a practical service item for HVAC technicians who regularly work on refrigerant circuits, air conditioning systems, and refrigeration equipment where valve core replacement is a routine maintenance task.

This kit is suited for residential and light commercial HVAC service applications. The included valve cores are compatible with standard Schrader valve fittings found on refrigerant lines, service ports, and charging ports. Having replacement cores bundled with the tool reduces truck stock complexity and keeps service calls efficient when a leaking or damaged core needs immediate swapping in the field.

Key Features

• Brass construction for corrosion resistance and durability at refrigerant service ports
• Compact knurled design provides controlled grip during core removal and installation
• Includes three valve cores, reducing the need for separate core stock on service calls
• Integrated container keeps cores organized and prevents loss in a tool bag or van stock

Compatibility

Designed for use with standard Schrader-type valve fittings commonly found on residential and light commercial refrigerant service ports.

Installation Notes

Valve core service is typically performed by licensed HVAC technicians during refrigerant system maintenance or leak repair. Before removing a valve core from a pressurized port, verify system pressure and follow all EPA Section 608 refrigerant handling requirements. Use the tool with controlled hand torque only — do not apply power tools or excessive force to the core seat. Reinstall cores to snug contact and verify with a leak check before returning the system to service.
