Manifold Gauge Set Series

Our Manifold Gauge Set Series supplies manifold gauges together with matching accessories as complete sets, ready to connect to equipment out of the box, saving the trouble of buying parts one by one. The line covers several tiers, including classic brass, aluminum 2-valve, aluminum 4-valve, digital ball valve, digital manifolds, and dedicated R744 sets, with a range of set numbers by refrigerant, fitting, and application. It suits automotive A/C repair shops and the charging, vacuum evacuation, and pressure testing of residential and commercial refrigeration equipment. Each set includes a manifold gauge and matching accessories such as charging hoses and quick couplers, with the exact configuration varying by model.

Brass Classic Gauge Sets (MG-B301-01/-02, MG-B302-01/-02): Built around a brass valve body with strong corrosion and pressure resistance. The B301 sets use a fixed standard gauge head, while the B302 sets have replaceable gauge heads. The MG-B302-02 is configured for R22, R134a, R404, and R410 refrigerants.

Aluminum 2-Valve Gauge Sets: Based on a lightweight aluminum valve body, with sheath styles including the Moon-cake Sheath, vintage One-piece Sheath, Square Black-Yellow Sheath, and FT Sheath. Configurations are offered to suit different needs, including R134a-dedicated, R1234yf-dedicated, multi-refrigerant, adjustable gauge head, Land Rover fitting (including a version that supports R1234yf), and new refrigerant versions, along with ball valve models (MG-S311-01, MG-M311-01/-02). The A302 sets are also available with a white, light blue, or black valve body.

Aluminum 4-Valve Gauge Sets (MG-A401/S401/M401 series): The four-handwheel, four-port structure can connect high-pressure, low-pressure, vacuum, and refrigerant supply lines at the same time, so vacuum evacuation, charging, and recovery do not require repeated hose changes. The S401 and M401 series each come in three configurations (basic, refrigerant version, and all-refrigerant version), and the A401 is the Moon-cake Sheath version.

Digital Ball Valve Gauge Sets (MG-E201/E301): A ball valve structure paired with digital electronic gauge heads gives intuitive pressure readings. The MG-E201-01 is the residential single-gauge set, and the MG-E301 is offered in commercial and automotive dual-gauge versions.

Digital Manifold Sets (MG-E302/E303/E305): Covering mid-level, advanced, and universal smart tiers, each with its own dedicated sheath. The E302 and E303 are both offered in commercial and automotive configurations, and the E305 is the universal smart model for technical service teams that want one tool that does it all.

R744 Set: Centered on the dedicated MG-R744 gauge, for R744 (CO₂) refrigerant systems, suited to technicians and repair shops servicing new automotive A/C systems that use CO₂ refrigerant.

From entry-level brass sets to professional digital manifold sets, the series meets the varied needs of repair businesses of different sizes in budget, refrigerant type, and working scenario.
