The MG-S401 Aluminum 4-Valve Manifold Gauge with Square Black-Yellow Sheath uses a four-handwheel, four-port design with a black VB-401 valve body. It comes with a PG-63 pressure gauge head by default, wrapped in a Square Black-Yellow Sheath, and the gauge head is replaceable.
Product Advantages
1. The four handwheels control different lines, so one connection is enough to switch between vacuum evacuation, charging, and leak checking.
2. The Square Black-Yellow Sheath sits stably, and the black-yellow color scheme is highly recognizable in the workshop.
3. The PG-63 gauge head is the same as on the MG-S201 H/L, so gauge head models are unified across the S series and spare parts are easier to manage.
Applicable Scenarios
Suitable for repair shops and chain outlets already using the black-yellow S series that need to upgrade to four-valve operation.
We can design and develop according to the needs of our customers to meet the requirements of different clients.
