YELLOW JACKET 78060 Complete Gas Pressure Test Kit - Accurate Manifold

Our review of the YELLOW JACKET 78060 Complete Gas Pressure Test Kit finds it best for HVAC technicians and experienced DIYers who need a compact, accurate tool for setting manifold pressure on natural or L.P. gas systems. The single biggest reason to buy is the sensitive diaphragm gauge calibrated in inches of water column and ounces per square inch, which makes it far easier to get reliable readings than a traditional manometer. Built to withstand higher over-pressure and including a tube nipple for quick hookup, it is a practical, field-ready gauge kit made in the United States.

Key Features

• Sensitive diaphragm gauge: Measures in inches of water column and ounces per square inch so technicians can set manifold pressure precisely for burners and furnaces.
• Improved lamination strength: The reinforced diaphragm (bellows) bonded to a brass plate resists higher over-pressure, reducing the chance of damage during testing.
• Single bellows design: Replaces older double bellows with a stronger seal that holds calibration and improves long-term reliability in routine service work.
• Tube nipple connection: The included tube nipple provides an easy, secure connection to a system manifold for faster setup and fewer leaks during measurement.
• Compact kit format: Smaller and easier to handle than a manometer, the kit travels easily in a tool bag and is simpler to use at tight service locations.

Who It's For

The YELLOW JACKET 78060 is aimed at HVAC professionals who frequently set or verify manifold pressure on furnaces, boilers, and other gas appliances, and at competent DIYers who understand gas systems and safe testing practices. Its clear calibration in in Wc and oz/in2 makes it especially useful when accuracy matters, such as when adjusting burners or confirming regulator output.

Those who should look elsewhere include users who need a digital data-logging gauge or a wider field of view for display; this is a mechanical diaphragm gauge and prioritizes rugged simplicity over electronic features. Also avoid this if you need adapters not included with the kit, since the package is basic by design.

Pros & Cons

Pros

• Accurate, sensitive diaphragm gauge provides reliable readings for manifold pressure adjustments.
• Improved lamination and single bellows on a brass plate increase durability under over-pressure conditions.
• Tube nipple allows quick connection to a system manifold for faster, cleaner testing.
• Compact and easier to use than a manometer, making it convenient in the field.

Cons

• Not a digital gauge, so it lacks electronic logging or advanced display features some users may want.
• Fit receives mixed feedback from customers, so additional fittings or adapters may be required for some manifolds.

Frequently Asked Questions

Is this gauge accurate enough for furnace switch testing?
Yes, customers report accurate readings and successful furnace switch testing thanks to the sensitive diaphragm calibration in in Wc and oz/in2.

Will the kit withstand accidental over-pressure?
The improved lamination and single bellows bonded to a brass plate are designed to resist higher over-pressure and reduce damage risk.

Does it include all fittings for every manifold?
The kit includes a tube nipple for easy connection, but some users report mixed fit; additional adapters may be needed for certain manifolds.
