The MG-B301 is the standard gauge head model in the Brass Classic manifold gauge series. Its valve body (model VB-301) is made of brass and comes with PG-01/PG-05 pressure gauge heads and a protective sheath, suitable for charging, vacuum evacuation, and pressure testing on automotive A/C and residential and commercial refrigeration equipment.
Product Advantages
1. The sturdy brass valve body offers strong corrosion and pressure resistance, withstanding repeated operation and pressure shocks in refrigerant systems over the long term.
2. Equipped by default with PG-01/PG-05 pressure gauge heads for clear readings and ready-to-use standard configuration; the gauge heads are fixed and non-replaceable, keeping the structure simple and stable.
3. The protective sheath around the valve body reduces everyday bumps and scratches and extends service life.
4. The applicable refrigerants are determined by the gauge head fitted, so the matching gauge head configuration can be chosen according to the equipment being serviced.
Applicable Scenarios
Suitable for automotive A/C repair shops, technicians servicing residential and commercial refrigeration equipment, and professional users who prefer classic brass and value durability and stability.
