Frequently Asked Questions
What is the difference between a 3 and 4 port manifold set?
A three-port manifold set is suitable for basic industrial applications, whereas a four-port manifold is necessary for large HVAC systems and vacuum pulling applications.
Where are Yellow Jacket tools, gauges & manifolds made?
Yellow Jacket manifolds and various HVAC products, such as hoses, gauges, adapters, recovery equipment, tools and kits, are made in the United States of America.
How to use mechanical manifold gauge sets?
Users should first connect the cooling line's high-pressure side to the red port of the measuring gauge and the low-pressure side should be connected to the blue port of the Yellow Jacket measuring gauge set. A vent / waste hose should be attached to the centre of the manifold set-up. Lastly, other gauges or micron meters should be attached to the additional ports of the manifold set.
