2026 Upgraded HVAC Valve Core Removal Tool Kit, 20 Micron Vacuum Rating, Dual 1/4"&5/16" Ports for R22 R410 R32 Systems

Product Brief This professional-grade HVAC valve core removal tool kit enables refrigerant loss-free operation, allowing technicians to replace valve cores without system shutdown or refrigerant release, significantly optimizing on-site efficiency. Engineered with a 20-micron vacuum rating, it performs accurate "Blank Off" vacuum testing during core replacement while preventing condensate release and maintaining system integrity. The dual-ended design features 1/4" and 5/16" interchangeable ports for maximum compatibility across service ports. Compatible with R22, R12, R407C, R410A, R404A, and R32 AC systems, this tool is ideal for home refrigeration equipment (excluding automotive AC). Precision double O-ring ball valve seals ensure leak-proof performance and safe maintenance, while the magnetic end cap securely holds valve cores during service without stopping the machine. Constructed from premium brass with a stainless steel valve stem, featuring strong impact resistance and an external anti-skid texture that prevents excessive force during operation.Specification - Material: Brass body, Stainless steel valve stem - Vacuum Rating: 20 microns - Port Sizes: 1/4" and 5/16" - Seal Type: Double O-Ring Ball Valve Seal - Compatible Refrigerants: R22, R12, R407C, R410A, R404A, R32 - Application: Home refrigeration equipment (Not for automotive AC)Package Contents - 1 × Multi-functional valve core removal tool
