The ASHCROFT 61379S02LXLL100 is an analog pressure gauge designed for accurate pressure measurement in mechanical, HVAC, plumbing, and industrial service applications. It features a 6-inch dial for easy readability and covers a pressure range of 0 to 100 psi. The gauge delivers 0.5% of scale accuracy, making it suitable for applications where reliable readings are critical. The aluminum case keeps weight manageable at 3.13 pounds while offering corrosion resistance in typical service environments. Wetted parts are constructed from stainless steel, providing compatibility with a wide range of media. The lower-mount configuration positions the process connection at the bottom of the gauge, which suits panel-mount and pipe-mount installations commonly found in mechanical rooms and equipment rooms.
This gauge is suited for residential and light commercial HVAC systems, plumbing pressure monitoring, boiler systems, compressor outlets, and general industrial piping. The 1/4-inch lower-mount thread connection makes it straightforward to install inline or on a tee fitting. The dry, no-fill design eliminates the need for liquid-filled housing, which simplifies handling and is appropriate for stable-pressure applications without excessive vibration or pulsation.
Designed as an OEM-style replacement or new-installation analog pressure gauge for residential and commercial HVAC, plumbing, and general industrial piping systems requiring a 1/4-inch lower-mount connection and a 0 to 100 psi range.
Installation is typically performed by a licensed HVAC technician, plumber, or qualified mechanical contractor. Shut down and depressurize the system fully before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the 1/4-inch NPT threads per standard plumbing practice and applicable IPC or IFGC guidelines. Do not over-tighten the gauge connection, as this can damage the internal bourdon tube or crack the case.
