Ashcroft 61379S04LXLL200 Pressure Gauge 6 in 0-200 Psi

Product Description

The ASHCROFT 61379S04LXLL200 is a 6-inch analog pressure gauge designed for accurate pressure monitoring in industrial and mechanical systems. It features a lower-mount 1/2-inch threaded connection, an aluminum case, and stainless steel wetted parts for compatibility with a wide range of media including water, air, steam, and mild chemicals. The gauge covers a pressure range of 0 to 200 psi with an accuracy of 0.5 percent of scale, making it suitable where reliable, readable indication matters. It is a dry-fill unit with no liquid filler, keeping weight down and simplifying installation in low-vibration environments. Licensed HVAC technicians, plumbers, and mechanical contractors install this type of gauge routinely on piping systems, pressure vessels, and mechanical equipment.

This gauge is suited for residential and commercial plumbing, HVAC, and general mechanical applications where a standard 6-inch dial provides clear visibility from a distance. The lower-mount configuration positions the connection at the base of the gauge, which is common for panel-mount or pipe-top installations. The stainless steel wetted parts make it appropriate for use with mildly corrosive fluids or potable water systems. The aluminum case keeps overall weight low while providing adequate protection in typical indoor or sheltered mechanical room environments. It is a direct-reading instrument requiring no external power source.

Key Features

• 6-inch dial diameter for high visibility at distance
• 0 to 200 psi pressure range with 0.5 percent of scale accuracy
• Lower-mount 1/2-inch threaded connection for pipe-top or panel-base installation
• Stainless steel wetted parts for compatibility with water, air, and mildly corrosive media
• Aluminum case construction keeps unit weight low
• Dry-fill analog design requires no liquid filler and no external power

Compatibility

Designed as an OEM-style replacement or direct-install analog pressure gauge for residential and commercial piping, HVAC, and mechanical systems requiring a 6-inch lower-mount gauge with a 1/2-inch threaded connection and a 0 to 200 psi range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes. Shut off and depressurize the system fully before removing the existing gauge or threading in the new one. Use appropriate thread sealant or PTFE tape on the 1/2-inch male threads and tighten to hand-tight plus a controlled amount per standard practice — avoid over-torquing, which can crack the gauge socket or distort the bourdon tube. Mount in a low-vibration location where possible; continuous vibration in a dry-fill gauge can shorten service life.
