It features a 4.5-inch dial for easy readability at a distance, a compound pressure range of 30 to 0 to 150 psi, and a stated accuracy of 0.5% of scale. The aluminum case keeps the unit lightweight without sacrificing durability, while the stainless steel wetted parts provide corrosion resistance in contact with system fluid. This gauge mounts via a rear flange configuration and uses a 1\/4-inch NPT thread connection. It is a dry-fill gauge with no liquid filler. Licensed plumbers, HVAC technicians, and pipefitters install this type of gauge during system commissioning, diagnostic work, and routine pressure testing.\u003c\/p\u003e\u003cp\u003eThe ASHCROFT 80246XLL suits residential and commercial applications where a compound pressure reading is needed. The compound range covering both vacuum and positive pressure makes it appropriate for refrigeration circuits, hydronic heating systems, water supply lines, and compressed air systems. The rear flange mount allows for panel or bracket installation where the gauge face must remain flush or recessed. The 4.5-inch dial is well suited for equipment rooms and mechanical spaces where technicians need to read pressure from several feet away without removing access panels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompound range of 30 to 0 to 150 psi covers both vacuum and positive pressure in a single gauge\u003c\/li\u003e\n\u003cli\u003e4.5-inch analog dial provides high visibility in mechanical rooms and equipment enclosures\u003c\/li\u003e\n\u003cli\u003e0.5% of scale accuracy supports reliable diagnostic and commissioning readings\u003c\/li\u003e\n\u003cli\u003eStainless steel wetted parts resist corrosion when in contact with system media\u003c\/li\u003e\n\u003cli\u003eAluminum case reduces overall weight while maintaining structural integrity\u003c\/li\u003e\n\u003cli\u003eRear flange mount allows secure panel or bracket installation\u003c\/li\u003e\n\u003cli\u003eDry-fill design with no liquid filler simplifies handling and disposal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style or replacement analog pressure gauge for residential and commercial HVAC, plumbing, refrigeration, and compressed air systems requiring a rear flange mounted, 1\/4-inch NPT, compound-range instrument.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or pipefitter in accordance with applicable local codes and ASME B40.100 gauge standards. Shut off system pressure and relieve any residual pressure in the line before removing or installing the gauge. Use appropriate thread sealant on the NPT connection and avoid over-tightening, which can damage the gauge socket or case. Verify that the system operating pressure falls within the gauge range before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 30 to 0 to 150 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 Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Rear Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Stainless Steel\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 80246XLL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51544008655154,"sku":"80246XLL","price":746.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95f8bcdc83bc5f5350f7bcbd810e2402_406d4a70-59a6-469f-b056-2a2be078c706.jpg?v=1785922920","url":"https:\/\/voomisupply.com\/products\/ashcroft-80246xll-pressure-gauge-4-5-in-rear-flange-30-0-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
