Ashcroft 61379S2LLLV/300 Pressure Gauge 6 in 300 Psi

Product Description

The ASHCROFT 61379S2LLLV/300 is a process industrial pressure gauge designed for demanding industrial and mechanical system applications. It features a 6-inch analog dial with a 0 to 300 psi pressure range and delivers 0.5% of scale accuracy, making it suitable for process monitoring where reliable readings are critical. The aluminum case houses stainless steel wetted parts, offering corrosion resistance in contact with measured media. The lower mount configuration accepts a 1/4-inch MNPT connection. This gauge is installed by licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals in process piping and pressure monitoring systems.

This gauge fits residential and commercial process piping applications where a durable, non-liquid-filled analog gauge is required. The 6-inch dial provides clear readability at a distance, making it well suited for boiler rooms, compressor skids, pump stations, and industrial fluid handling systems. The lower mount orientation simplifies panel or pipe installation in vertical run configurations. The IP66/NEMA 4X rating and CRN certification extend its use to outdoor and wash-down environments as well as Canadian registered pressure vessel applications.

Compatibility

Designed as an OEM-style replacement or direct-install analog pressure gauge for process piping, boiler, compressor, and pump system applications requiring a 1/4-inch MNPT lower mount connection and a 6-inch dial format.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial technician. Depressurize and isolate the system before removing any existing gauge or fitting. Apply appropriate thread sealant to the 1/4-inch MNPT connection per local plumbing code requirements. Do not overtighten the threaded connection using the case as leverage; use the wrench flats on the fitting only.
