What is a dual gauge?
Dual-gauge track can consist of three rails, sharing one "common" rail; or four rails, with the rails of the narrower gauge lying between those of the broader gauge. In the three-rail configuration, wear and tear of the common rail is greater than with the two other outer rails.
What is an OO gauge?
- O-16.5 is the modelling of approximately 2ft 3in gauge prototypes in 7mm scale using OO gauge track (16.5mm).
- On30, is ¼in :1ft scale, using OO gauge track, therefore producing close to prototype 2ft 6in gauge.
- 16mm narrow-gauge uses 16mm:1ft models, running on 32mm gauge track to produce models of 2ft narrow-gauge prototypes.

What is the purpose of a gauge manifold set?
What Is a Manifold Gauge Set Used For? Manifold gauges are used to monitor heating or cooling systems, specifically the pressure of refrigerants. These tools are used to control the flow of pressure or gas. HVAC gauges can either be small handheld devices, or bigger machines used in a professional HVAC shop.

What is better a 3 or a 4 port manifold set?
Normally, a three-port manifold is adequate for general tasks. For vacuum pull applications and larger HVAC systems, four ports may be necessary.
What are the 2 types of gauges found on a gauge manifold set?
All manifold gauges have high- and low-pressure gauges. Some older designs come with three gauges - one is used for measuring compressor output.
What should AC pressure be with engine running?
The system should be about 25 to 30 psi on the low side and 200 to 250 psi on the high side. If the ambient temperature is higher or lower than normal (70 to 80°F) the pressures will go up or down accordingly.
What should AC manifold gauges read?
What are my A/C pressure readings telling me about my A/C system?An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.250 PSI / 30 PSI = You have air somewhere in the system.250 PSI / 50 PSI = The system is overcharged and the condenser is not cooling.More items...•

What is a main difference between two valve and the four gauge manifold?
2-valve manifold gauges are more lightweight compared to their 4-valve counterparts. Usually, 2-valve manifold gauges are used on gauge pressure transmitters (the user needs to isolate the transmitter and vent the pressure off).
How do you read a manifold gauge?
GENERAL MANIFOLD INFORMATION: The right (red) side of the manifold is the high side and the red gauge is the high pressure gauge. The left (blue) side of the manifold is the low side and the blue gauge is the vacuum/pressure gauge.
What are the parts of manifold gauge?
GAUGE MANIFOLD It consists of three chamber devices; low-pressure chamber, high-pressure chamber, and utility chamber. These chambers provide control over the flow of gas and pressure. These are crucial for HVAC gauges basic performance.
Where should the yellow hose of manifold gauge be connected?
They are color-coded to distinguish them. The blue hose is for the low-pressure gauge, while the red one is for the system's high-pressure valve. The yellow hose can be used for both low and high-pressure valves. It goes to whichever valve is open.

What is a manifold gauge set?
An air conditioning manifold gauge set is a must-have tool for anyone who is interested in performing some basic system work at home, such as checking pressure in a/c lines, determining if there's a leak, adding small amounts of refrigerant, or performing a complete evacuation and recharge. Compact, hand-held manifold gauge sets are used universally when servicing home air conditioning systems as well as automotive ones, and professional technicians use them same way you can in your back yard. Although shops typically have large, costly machines that do the evacuating and recharging work, similar results can be achieved with equipment that can be purchased inexpensively and stored easily.
How do hoses work on a manifold?
Hoses on a/c manifold sets easily connect and disconnect to fittings on the vehicle with Schrader style valve couplings. Some hoses are designed with "manual" couplers that feature a quick release button on top which must be depressed manually to lock the connection in place, and other hoses are designed with "automatic" couplers which click into place with a simple push. Instead of using a pushbutton to release, a lock ring is moved by hand. Whichever style is used, it is important that the blue hose is connected to the vehicle's low pressure side, and the red hose is connected to the vehicle's high pressure side.
Does a vacuum gauge have a reading?
Only the low-pressure side gauge has a reading for vacuum. When the system is being evacuated, the needle will travel to the other side of zero to reflect negative pressure (vacuum) in the lines as shown here. If the system holds vacuum pressure without dropping for 30 minutes after being evacuated, there are no leaks in the system.
What is the blue side of a manifold?
The left (blue) side of the manifold is the low side and the blue gauge is the vacuum/pressure gauge. Separate passages from the low and high side fittings to their respective gauges allow one to check pressure and vacuum readings. The manifold body connects all three fittings to each other by internal passages.
How to disconnect a manifold?
To disconnect the manifold when the system is filled and operating properly, close the BLUE (low side) and RED (high side) hand valves on the manifold. To disconnect the manual coupler, turn the knob on it until finger tight. Slide the coupler sleeve up, releasing the coupler from the vehicle’s service port.
Can you open the high side valve on a manifold gauge?
Caution: Never open the high side valve on manifold gauge set when the A/C System is operating.
