❄️ Zero Refrigerant Loss Design, Cut Massive Maintenance Cost
Equipped with precision solid brass quarter-turn ball valve. Instant full sealing when switching cores, completely stops refrigerant leakage during replacement. Skip expensive refrigerant refills and time-consuming vacuum pumping, maximize working efficiency and save long-term service expense.
🛠️ Dual SAE Port Universal Compatibility for All Cooling Systems
Integrated SAE 1/4" & 5/16" dual ports, paired with R410/R32 brass adapter. Fully compatible with R22, R407, R410, R404, R32, R600 refrigerants, fits split air conditioners, cold storage equipment and most stationary HVAC high-pressure units.
🔩 Premium Brass Build + Heat-Resistant Teflon Seals for Long Service Life
Forged solid brass tool body resists rust, high pressure and extreme working temperature. Included 20 replacement valve cores adopt thick Teflon sealing rings with fluorine resistance, avoiding frequent core aging and air leakage even under long-term high-load use. Knurled anti-slip grip prevents over-torquing damage during operation.
Pressurized Direct Replacement, 10X Faster Repair Workflow
No need to release pressure or power off cooling equipment. Grab, replace and lock cores directly on active pressurized systems. One-step operation eliminates multi-step depressurization & recharging procedures, slashing single valve maintenance time from minutes to seconds for busy field technicians.

Common FAQs
Q1: Can this tool work for automotive air conditioning systems?
Q1: Can this tool work for automotive air conditioning systems?
A: This kit is designed for stationary HVAC, household AC and refrigeration units; not recommended for automotive AC service ports.
Q2: Does the ball valve seal tightly under high system pressure?
Q2: Does the ball valve seal tightly under high system pressure?
A: Yes, precision machined solid brass ball valve forms full airtight seal within 1/4 turn, reliable for standard high-pressure cooling system working pressure.
Q3: Are the included valve cores resistant to high temperature refrigerant?
Q3: Are the included valve cores resistant to high temperature refrigerant?
A: Each spare core comes with high-temperature fluorine-resistant Teflon gaskets, stable under long-running AC heat without seal aging or leakage.
Q4: Do I need to evacuate and recharge the system after replacing cores?
Q4: Do I need to evacuate and recharge the system after replacing cores?
A: No. The sealed ball valve maintains full system pressure during core swap, no vacuum pumping or refrigerant refill required after maintenance.
