Frequently Asked Questions:

Q. What is a 3 port manifold set?

A. The red hose of a 3 port manifold set connects to the high-pressure port for liquids, the yellow hose to the centre port for recovery or charging and the blue hose to the low-pressure port for vapour.

Q. What does a refrigeration gauge mean?

A. Refrigeration gauges are compound gauges used for measuring both vacuum and positive pressure. They have graded dials with 270 degrees displays and a pressure range of either vacuum-150 PSI or vacuum-300 PSI.

Q. What components make up a manifold gauge?

A. It is made up of three-chamber devices: a utility chamber, a high-pressure chamber and a low-pressure chamber. These chambers offer pressure and gas flow regulation and are essential for the basic operation of HVAC gauges.
