Yellow Jacket 19305 Ac Schrader Valve Core Pack

Product Description

The YELLOW JACKET 19305 is a 10-piece pack of A/C Schrader valve cores designed for use in refrigerant system service valves. Schrader cores control access to refrigerant circuits, enabling technicians to charge, test, and evacuate HVAC and refrigeration systems without uncontrolled refrigerant release. These cores are the serviceable internal component of standard Schrader-type valve bodies. Replacing a leaking or damaged core is a routine maintenance task that restores system integrity and prevents refrigerant loss. Having a pack of 10 on hand covers multiple service calls.

This core pack is suited for residential and light commercial A/C system service. Common applications include repairing leaking valve cores on suction and liquid line service ports, installing fresh cores during refrigerant recharge procedures, and restoring a tight seal on appliance valves after evacuation. HVAC technicians performing seasonal maintenance or troubleshooting refrigerant loss will find this pack a practical addition to their service inventory.

Key Features

• 10 Schrader valve cores per pack for multi-job service coverage
• Designed for use in A/C appliance service valves
• Supports refrigerant charging, system testing, and evacuation procedures
• Direct replacement for leaking or damaged cores to stop refrigerant loss
• Compatible with standard Schrader-type valve body ports found in HVAC and refrigeration systems

Compatibility

Designed as an OEM-style replacement for standard Schrader valve cores used in residential and light commercial A/C and refrigeration service valves.

Installation Notes

Schrader valve core replacement is performed by licensed HVAC technicians using a valve core removal tool. Recover any residual refrigerant and depressurize the circuit before removing the existing core to prevent uncontrolled refrigerant release. After seating the new core, pressure-test the valve port to confirm a leak-free seal before recharging the system. Follow EPA Section 608 requirements for refrigerant handling throughout the service procedure.
