It features a 3.5-inch dial face, stainless steel case, and bronze wetted parts, making it well suited for demanding service environments. The center back mount configuration allows direct panel or piping installation with a 1\/4-inch threaded connection. Accuracy is rated at 1 percent of full scale, which meets typical industrial and mechanical service requirements. This gauge is dry-fill, with no liquid filler, keeping it lightweight at 0.25 pounds. Licensed plumbers, pipefitters, HVAC technicians, and mechanical contractors are the primary installers of this type of instrument.\u003c\/p\u003e\n\u003cp\u003eThis gauge is applicable in residential, commercial, and light industrial settings where compound pressure readings are needed, such as refrigeration systems, hydronic heating loops, compressed air lines, and water supply monitoring. The stainless steel case resists corrosion in humid or wash-down environments, while the bronze wetted parts are compatible with a wide range of non-corrosive media. Center back mount placement suits panel-mounted instrument arrays and direct pipe-tapping applications where a clean, flush-mounted appearance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompound pressure range: 30 to 0 to 100 psi for both vacuum and positive pressure measurement\u003c\/li\u003e\n  \u003cli\u003e3.5-inch analog dial for easy field reading at a distance\u003c\/li\u003e\n  \u003cli\u003e1 percent of full-scale accuracy for reliable instrumentation-grade readings\u003c\/li\u003e\n  \u003cli\u003eStainless steel case provides corrosion resistance in harsh or wet environments\u003c\/li\u003e\n  \u003cli\u003eBronze wetted parts compatible with common non-corrosive media including water and air\u003c\/li\u003e\n  \u003cli\u003eDry-fill design — no liquid filler — reduces weight and simplifies handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure gauge for residential and commercial mechanical systems requiring a 1\/4-inch center back mount, 3.5-inch dial, compound range analog gauge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local mechanical codes. Depressurize and isolate the system fully before removing an existing gauge or making the threaded connection. Apply appropriate thread sealant to the 1\/4-inch male threads and tighten to the fitting using a wrench on the gauge's hex fitting — never apply torque through the case or dial. Verify the system pressure range is within the gauge's rated scale 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: 30 to 0 to 100 psi (compound)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1 percent of full scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Center Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Bronze\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: 0.25 pounds\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: 35109A2BLLV\/100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51541682323762,"sku":"35109A2BLLV\/100","price":237.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3bbea092f5b4780ca847ece6230fc4a_21d48551-ad3e-4357-91ff-bf39f9e919e0.jpg?v=1785882137","url":"https:\/\/voomisupply.com\/products\/ashcroft-35109a2bllv-100-pressure-gauge-3-5in-30-0-100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
