Tigbear R410A Recharge Kit AC Charging Hose
This kit features a 59-inch durable refrigerant charging hose with 1/4″ SAE male and female flare threads. It supports a maximum working pressure of 800 PSI and a burst pressure of 4000 PSI, making it robust for various AC servicing tasks. It includes an 80 mm low-pressure gauge (0-550 PSI) and a low pressure switch valve with a 1/4″ thread.
The R410A swivel adapter converts 5/16″ SAE vacuum ports to 1/4″ SAE gauge hose ports, improving compatibility with most mini split systems. Also included is a R134A tank adapter with a removable valve core to speed up vacuuming. Constructed from brass, these adapters are designed for long-term use with minimal leak risks.
BACOENG 3.6CFM AC Vacuum Pump and Gauge Set
This vacuum pump kit includes a 3-way manifold gauge set with an easy-to-read sight glass made from anodized aluminum. The compact vacuum pump operates at 3.6 CFM flow rate and 1/4 HP power, delivering an ultimate vacuum level of 0.8 Pa, enough to evacuate refrigerant lines efficiently.
The package has three 5-foot high-pressure hoses compliant with SAE-J2196 standards for durability and safety. The hoses are color-coded red, blue, and yellow for high-pressure, low-pressure, and vacuum pump lines respectively. It also features an included R410a mini split adapter for direct servicing of R410A systems.
CANIPHA R410A Mini Split Adapter Kit
The CANIPHA adapter kit offers a sturdy brass build resistant to high pressure and deformation. Its thimble design and sealing ring provide a strong and leak-free connection, a crucial feature for maintaining system integrity during refrigerant charging.
The coupling nut has deep knurling for quick hand-tightening without requiring tools. This adapter works well with most R410A mini split air conditioners, making it a valuable tool for HVAC professionals and DIYers alike. It also enables seamless conversion of 5/16″ SAE ports to 1/4″ SAE gauge hoses.
VTG VOGTEN 4.5 CFM AC Vacuum Pump and Gauge Set
This comprehensive kit features a 1/3 HP single stage vacuum pump with a higher flow rate of 4.5 CFM, suitable for evacuating mini split systems quickly. It includes a 3-way manifold gauge set with precise dial readings for temperature, pressure, and refrigerant flow.
Additional accessories include three hoses, two R410a adapters converting 1/4″ male to 5/16″ female ports, vacuum pump oil, a puncture can tap, a valve core wrench, and a convenient storage bag. The pump casing is made of aluminum alloy for excellent heat dissipation and corrosion resistance, ensuring durability.
Pioneer KWIK-E-VAC Line Set Flushing Kit
Designed specifically for flushing copper line sets, this kit efficiently removes air and non-condensable gases from the lines and indoor unit. It serves as a cost-effective and practical alternative to expensive quick-connect line sets often used in mini split installations.
The flushing kit simplifies evacuation by cutting down the time and effort needed for line cleaning, resulting in improved air conditioner performance and reliability. It is a handy accessory for HVAC technicians aiming for thorough mini split system maintenance.
Buying Guide for Mini Split Recharge Kits
Compatibility with Refrigerant Type
Ensure the recharge kit supports the refrigerant your mini split system uses, typically R410A or R134A. Many kits specify compatibility; selecting a kit with proper adapters tailored to R410A systems is critical for an effective seal and leak prevention.
Hose Quality and Length
Look for hoses manufactured with durable materials such as reinforced rubber, rated for high pressures (800+ PSI) to prevent bursting. Lengths around 5-6 feet offer flexibility during recharging tasks, without excessive bulk or risk of tangling.
Gauge Accuracy and Type
Choose gauge sets that provide clear, easy-to-read dials or sight glasses for monitoring pressure and refrigerant flow accurately. Anodized aluminum manifolds enhance durability, and manifold sets with three or four ports allow full system diagnostics and servicing.
Vacuum Pump Performance
If included, vacuum pumps should have sufficient flow rate (CFM) to evacuate air and moisture quickly from the system. Pumps with 3.6 to 4.5 CFM and ultimate vacuum levels under 1 Pa meet most residential mini split requirements effectively.
Adapters and Seal Quality
Brass adapters with reliable sealing rings minimize leakage risks. Quick-connect or swivel adapter designs ease installation and removal during servicing. Deep knurling on coupling nuts aids tightening without tools, improving efficiency and safety.
Additional Tools and Accessories
Extra items like valve core removers, can taps, vacuum pump oil, and storage cases add value by simplifying the recharge process and providing all necessary components in one kit.
Portability and Storage
Kits that include storage bags or hard cases make transportation easy for HVAC professionals. Compact and lightweight designs support usage on residential or commercial sites without added logistical hassle.
When choosing a mini split recharge kit, balancing quality, features, and compatibility with your specific AC system ensures effective refrigerant management, maximizing performance and longevity of your unit.
