Manifold Gauge with Brass Body

This is a complete manifold gauge set, with high and low oil pressure gauge valve, pressure hoses, etc.

We call it the R22, R410a manifold gauge set because it is suitable for R22, R410 refrigerant, and another common refrigerant. The specific technical data is the following.

How can you find the perfect model for your work?

Choose the length of the pressure hose you need, we have standard 36’’,60’’,72’’.

Choose the refrigerant you will need, normally R12, R22 and R502 can be together, but R410, R134a should be separate because of the different pressure.

Choose the body material you need, brass, or aluminum.

Choose the protective cover or not.

The R22, R134a manifold gauge set has all the good features with a single gauge, like high-quality brass or aluminum alloy body, good design for hand for your easy operation, and durable quality.

Manifold Gauge with Sight Glass

This is a complete R410 R134a manifold gauge set, also includes R12, R22, and R502 refrigerant, along with a pressure hose.

The difference with the above manifold gauge set is this type has a sight glass on the body, to help you check the refrigerant flow during your repair work for Air conditioning.

You can follow the above method to choose the most suitable manifold gauge for yourself. If you have a special request or there is anything not clear about our manifold gauge, just contact us for detail.

Manifold Gauge with Aluminum Body

This is also a complete manifold gauge with a pressure hose but wants you to pay attention to the R410a refrigerant. R410 has a higher pressure than other common refrigerants, so when you order an R410a manifold gauge, please remind us of that.

This type of manifold gauge is similar to the above two types of manifold gauge, the difference is this type has an Aluminum body, with or without sight glass, but the same function. You can pick the major specifications and form your satisfied manifold gauge set.

If you want to buy the parts for the manifold set, maybe for your current set, see the following specs to choose from.

What is a Manifold Gauge, and How Does It Work?

What is a Manifold Gauge, and How Does It Work

A manifold gauge is a tool for checking the pressure in HVAC systems.

It allows the technician to check the system pressure at different locations and then determine which components of the system need to be repaired or serviced.

The manifold gauge consists of a collection of valves that allow for branch connections to be made directly into an HVAC line.

The valve assembly is usually fastened together using a union fitting.

A gauge and a handle are attached to the manifold spool so that when the handle is turned, it opens and closes each individual valve in turn.

What Are the Parts of the Manifold Gauge?

A manifold gauge has three main parts. The first is the body which contains the valves and connects to the input and output of the system.

The second part is a pressure gauge that indicates how much pressure is present in the HVAC line.

The third part is a handle, usually located on top or bottom of the manifold spool, which turns the valves on and off.

Which is Better: a 3 or a 4 Port Manifold Gauge?

Pressure gauges are sold with either 3 or 4 ports.

The difference between the two is that a three-port gauge has one more connection point on the side of the head, allowing for another set of readings without disconnecting anything.

A manifold gauge is always used in pairs, so having an extra connection isn’t needed unless you also want to run multiple pressure tests at the same time.

If you are reading pressure in one part of an HVAC system, chances are the rest is fine. So it may be helpful to have two separate manifold gauges.

The 4-port gauge simply reads more accurately because it has a higher number of ports, making it less likely that there will be any errors in reading.

How Do You Use a Mechanical Manifold Gauge Set?

How Do You Use a Mechanical Manifold Gauge Set

Manifold gauge sets are used by selectively opening valves on the head to determine where air leaks are occurring within an HVAC system.

The manifold is hooked up to the airline of an HVAC system which is typically fed from either a large trunk line or directly from the compressor.

The first step in using a mechanical manifold gauge set is to close all of the inlet valves on the manifold head.

These valves are typically closed by screwing in the stem of the valve with a clockwise motion.

Next, open one port at a time, beginning with the port farthest from the pressure gauge—this forces air out of that particular hose and into the system being tested.

Close the valve to check the system pressure.

There are four different pressures typically tested, including low side, high side, suction line, and condensate line.

The low-pressure gauge is typically attached to the discharge of an HVAC unit.

High-pressure measurements are taken by hooking up the port on the manifold set to a point before any power equipment to determine the pressure at that point in the system.

The suction line is usually attached to a fitting on a compressor or an outdoor unit.

Finally, condensate line pressure measurements are taken from a plant room or outdoor unit.

Suction Side Measurements:

When taking low side readings, the valves should be opened while the pressure remains closed.

Finally, close all of the valves on the head.

The final step in using a mechanical manifold gauge set is to check all four lines again for any variation in pressure readings.

By opening and connecting one valve at a time, it can quickly be determined where the air is escaping within an HVAC system.
