Invaluable tool for a geothermal closed loop furnace
This review is for the MEASUREMAN Brass Gauge Adaptor 1/4NPT Female,2-1/2 OAL x 1-2/5" x 1/8" Probe with Stainless Steel Sheath. The 1/8" probe comes with a "Pete" plug. This is a self sealing valve to allow the probe to be inserted and measure the pressure of a closed water loop, commonly found in residential geothermal heat pumps. I'm sure there are other applications, but my application was to check and service my 15 year old geothermal unit. The simplest solution is to just hook a pressure gauge to the 1/8" probe, insert it into the pete plug, and read the pressure. You can see from the photos how you can screw the probe onto a pressure gauge with a 1/4" NPT male fitting. In my case, there were already 2 Pete plugs installed on my furnace, so the included one was not needed or used, but will be good for a spare. It is an invaluable tool for a homeowner, or geothermal technician to check the pressure of the closed loop of a geothermal furnace. I believe MEASUREMAN also sell a kit including the gauge, or at least did at the time of this review. It is made from brass and stainless steel. Note: the gauge in the picture is not included, but there just to illustrate how the probe can be used.

Has a needle protector
Works great. Even came with a cover that screws on to protect the needle.

Great for geothermal technicians
I work on geothermal units and these are perfect for my gauges so I can read pressures on the loops

Product function
Seems good quality except the plug has no hole so you can stick the probe in and threw to check pressure
