It features a 4.5-inch analog dial with a measurement range of 0 to 400 psi and delivers 0.5% of scale accuracy, making it suitable for systems where precise pressure monitoring is critical. The gauge uses a 1\/4-inch MNPT rear connection and mounts via a rear flange configuration. Stainless steel wetted parts resist corrosion in harsh process media, while the aluminum case keeps overall weight low at 2.5 pounds. A glass lens provides a clear, durable display face. Licensed HVAC technicians, process pipefitters, and industrial plumbers typically specify and install this gauge.\u003c\/p\u003e\n\u003cp\u003eThis gauge is used in process piping, industrial fluid systems, compressed air lines, and hydraulic circuits where a rear-flange panel-mount configuration is required. The rear flange mount allows direct panel or bulkhead installation with a clean front-face appearance. The no-fill, dry-service design means no glycerin or silicone fill is present, which suits environments where fill-fluid leakage is a concern. It is rated to IP66 and NEMA 4X standards, confirming suitability for washdown, outdoor, and corrosive-atmosphere installations. CRN certification supports use in Canadian pressure vessel and piping systems where provincial registration is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 400 psi measurement range with 0.5% of scale accuracy\u003c\/li\u003e\n  \u003cli\u003e4.5-inch analog dial for easy readability at distance\u003c\/li\u003e\n  \u003cli\u003eStainless steel wetted parts for corrosion resistance in aggressive media\u003c\/li\u003e\n  \u003cli\u003eRear flange mount for clean panel or bulkhead installation\u003c\/li\u003e\n  \u003cli\u003eIP66 and NEMA 4X rated for washdown and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eCRN certified for Canadian pressure system compliance\u003c\/li\u003e\n  \u003cli\u003eDry service (no liquid fill) eliminates fill-fluid contamination risk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style process gauge for industrial and commercial pressure monitoring applications requiring a 1\/4-inch MNPT rear connection with rear flange mounting.

Depressurize and isolate the system before removing any existing gauge or fitting. Apply appropriate thread sealant to the 1\/4-inch MNPT threads per site or code requirements, and tighten using a wrench on the gauge hex fitting — do not apply torque through the case body. Verify the process medium and pressure range are within the gauge specifications before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 400 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.5% of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size and Type\u003c\/strong\u003e: 1\/4 inches MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Rear Flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Glass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CRN, IP66, NEMA 4X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1379\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHCROFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 93754XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51539178520882,"sku":"93754XLL","price":726.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_9e950a85-62a3-4fcf-b77a-e82cc695d65a.jpg?v=1785836022","url":"https:\/\/voomisupply.com\/products\/ashcroft-93754xll-pressure-gauge-0-400-psi-4-5in-rear-flange","provider":"Voomi Supply","version":"1.0","type":"link"}
