BACOENG 3.6CFM AC Vacuum Pump and Gauge Set
This BACOENG Vacuum Pump Kit features a 3-way manifold gauge set with an oversized sight glass for clear refrigerant flow observation. The compact AC vacuum pump delivers a strong 3.6 CFM flow rate powered by a 1/4HP motor, achieving an ultimate vacuum of 0.8Pa. High-pressure hoses comply with SAE-J2196 standards, including color-coded red, blue, and yellow hoses, each 5 feet long. This set supports R410A refrigerants, making it suitable for mini split air conditioner evacuation and recharging tasks.
R410A Recharge Kit AC Charging Hose with Manifold Gauge
This Tigbear R410A Recharge Kit offers 59-inch durable refrigerant charging hoses with 1/4” SAE male and female flare threads. The low-pressure gauge reads up to 550 PSI and the hoses can work up to 800 PSI, bursting at 4000 PSI. It includes a straight swivel brass adapter for converting 5/16″ SAE ports to 1/4″ SAE gauge hoses, as well as an R134A tank adapter with valve core removal for ease of vacuuming and charging across different refrigerant types, including R410A and R134A.
Wells R410A Mini Split Adapter Kit, 12PCS
The Wells 12-piece Adapter Kit includes straight, 45-degree, and 90-degree adapters with thimbles, valve core remover, and gaskets. Constructed from high-quality brass alloy, these adapters provide excellent sealing to prevent fluorine leaks. The versatile kit is perfectly suited for HVAC repairs and mini split vacuum pump port conversions, ensuring safe, reliable, and durable connections for R410A charging applications.
SURIEEN R410A Recharge Kit AC Charging Hose
The SURIEEN charging hose kit accommodates R410A, R134A, and R22 refrigerants. Equipped with 59-inch high-strength hoses rated at 800 PSI working pressure, it comes with a multi-scale gauge for easy monitoring of different refrigerants. This kit features heavy-duty brass connectors resistant to corrosion and oxidation, along with a rubber-coated gauge to prevent damage. Removable valve cores enhance vacuuming efficiency, ideal for mini split HVAC use.
CANIPHA R410A Mini Split Adapter Kit
The CANIPHA Mini Split Adapter offers a compact brass coupling nut designed for secure 5/16″ to 1/4″ SAE port adaptations. It features deep knurling for easy hand-tightening and a thimble design with a sealing ring to prevent leaks. Manufactured from durable brass, it resists deformation and high pressure, making it suitable for new R410A mini split air conditioners and refrigeration systems requiring reliable vacuum pump connections.
Buying Guide for Mini Split Charging Kits
Choosing the right mini split charging kit involves understanding specific features and compatibility. Below are key factors to consider:
Refrigerant Compatibility
Mini split systems commonly use R410A refrigerant. Ensure the kit supports R410A and, if needed, other refrigerants like R134A or R22. Multi-refrigerant gauges and adapters expand versatility.
Vacuum Pump Capacity
A higher CFM (cubic feet per minute) rating means quicker evacuation of air and moisture from the system. Look for pumps around 3.6 CFM or higher for efficient operation.
Hose Quality and Length
Durable hoses compliant with SAE-J2196 standards are preferred for high pressure resistance and longevity. Hose length around 5 feet or longer offers flexibility during servicing.
Manifold Gauge Features
A manifold with clear gauges and sight glasses allows accurate refrigerant flow observation. Multi-scale gauges for R410A, R134A, and R22 improve user convenience.
Adapter Types and Sealing
Adapters should provide excellent sealing to prevent refrigerant leaks, especially when connecting 5/16” SAE ports to 1/4” SAE hoses. Kits offering various angled adapters and valve core removers add versatility and ease of maintenance.
Material Durability
High-quality brass construction for adapters and heavy-duty rubber on hoses increase reliability and safety. Resistance to corrosion and mechanical wear ensures longevity.
Ease of Use
Features like deep knurled nuts for hand-tightening, removable valve cores, and color-coded hoses improve the working experience. Compact and portable designs support convenient transport and storage.
