Yellow Jacket Yellow Jacket 78060 Complete Test Kit, 0-35" W.C

I recently purchased the Yellow Jacket 78060 Complete Gas Pressure Test Kit for fine-tuning my furnace and gas appliances, and it’s become my go-to tool for low‑pressure diagnostics. ** Standout Features - Sensitive diaphragm gauge (0–35″ W.C. & oz/in²) — provides crisp, precise readings perfect for natural gas and LP adjustments. - Robust single‑bellows brass diaphragm — engineered to resist over‑pressure far better than older dual‑bellows models. - User‑friendly design — includes a tube nipple fitting for quick manifold connections and comes in a hard carrying case—much simpler than using a manometer. - Made in the USA — built to last with quality craftsmanship. ** What I Loved - Exceptional accuracy — real-world use confirms it's spot-on compared to pricier digital gauges. One pro reviewer even said it was “spot‑on compared to professional digital equipment. - Durable and well-made — sturdy construction and a protective case mean this tool can withstand worksite conditions. - Great value — around $75 gives you everything you need in a compact analog kit that's faster and cleaner than bulky manometers. * Minor Quirks - Analog readability — lacks a digital display, so it requires steady eyes and care under low light. - Limited range — the 0–35″ W.C. scale is ideal for most gas setups but not suited for higher-pressure systems. - No instructions on how to use, but a YouTube search will fix that. ** Final Verdict** For HVAC technicians, DIYers, or homeowners working with gas appliances, the Yellow Jacket 78060 is a smart investment. It delivers razor-sharp accuracy, professional-grade durability, and easy usability—all in a portable package. Whether you're installing, troubleshooting, or certifying gas systems, this kit handles it cleanly and correctly. Highly recommended!

Needed to address the new regulator for my new garage propane heater. I'm sure glad I bought this pressure gauge that has the water column right ends. I had the unit running right out of the box on the regulator presets and thought everything was fine. When I connected the gauge it pinned the needle in the pressure was way too high. The Flame looked the same to me before and after adjustments. I don't know why it matters if the pressure is high or low but now I have the Peace of Mind knowing it's right on. It will be handy to have for your son travel trailers, motorhomes and other campers as well as home use. Very satisfied with the product the back and the delivery and everything about it.

My Dometic fridge worked on 110V AC just fine and appeared to be working on gas; but it wasn't cooling well. The thermal link was good, it didn't need to be reset, the lights were on. the indicator lights weren't blinking like if there was a gas failure, there was a flame, the chimney was hot and the fan was on. When I pulled the test plug and attached this I discovered that the one year old regulator was only putting out 5" with the fridge on and 6" with it off. The side regulated propane port gave the same reading. I replaced the regulator and now have 12" on the gauge and 11" with the water heater on. This saved an expensive visit to the dealer or visit from a mobile RV tech. This gauge now lives in the RV along with the multi-meter.

I purchased this to do leak tests on propane systems. Overall the product is excellent and has proven to be accurate. The rubber tips on the hose do tear after awhile, but they are replaceable. Leave the meter in the case to protect it from getting out of calibration. The rubber hose is plenty long enough to make a connection. If you test natural gas or propane pressures, I'd say smash the buy button on this.

Use it almost daily as a RV technician, have tested it against a u-tube manometer and it's bang on. I don't think it's an adjustable manometer though which is it's only downfall

Great pressure sensitive device. Accurate!

This is a nice quality unit. The gauge is fixed to the container, or I haven't used enough force on it to pop it out. It is not a big deal and it will probably lead to a longer life for the gauge. The hose good quality and fairly long, at least 3' maybe 4'. Worked well for adjusting my propane regulators and fireplace valve when I switched from NG to LP. I won't use this everyday but it is nice to have in to toolbox for when i need it next time.

Item is not in use as yet. Needed for mechanical class.
