It features a 3.5-inch analog dial with a 0 to 15 psi range and delivers 1% of scale accuracy. The case is constructed from 304\/316 stainless steel, and the Bourdon tube is 316 stainless steel, making this gauge well suited for applications involving moisture, vibration, or corrosive media. The 1\/4-inch NPT lower-mount connection allows direct inline or panel installation. A polycarbonate lens protects the dial face. Licensed and certified trades install this gauge in plumbing, HVAC, and industrial process systems where reliable low-pressure indication is required.\u003c\/p\u003e\n\u003cp\u003eThe ASHCROFT 83169 is appropriate for residential and light commercial plumbing systems, HVAC hydronic loops, compressed air lines, and industrial process piping operating at pressures up to 15 psi. The liquid-filled design dampens needle vibration and protects internal components against pulsation and pressure spikes, extending service life in pump-discharge or compressor-outlet applications. The lower-mount NPT connection suits installations where the gauge mounts directly to a pipe tee, manifold, or test port from below.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 15 psi pressure range with 1% of scale accuracy\u003c\/li\u003e\n  \u003cli\u003e3.5-inch analog dial for easy reading at a distance\u003c\/li\u003e\n  \u003cli\u003eLiquid-filled design dampens vibration and protects against pulsation\u003c\/li\u003e\n  \u003cli\u003e304\/316 stainless steel case and 316 stainless steel Bourdon tube for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT lower-mount connection for direct inline installation\u003c\/li\u003e\n  \u003cli\u003ePolycarbonate lens with IP54 and IP65\/NEMA 4 environmental ratings\u003c\/li\u003e\n  \u003cli\u003eCompliant with CRN, PED, and RoHS standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style or replacement industrial pressure gauge for plumbing, HVAC hydronic, compressed air, and light industrial process systems requiring a 1\/4-inch NPT lower-mount connection and a 0 to 15 psi measurement range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber, pipefitter, or HVAC mechanic. Depressurize and isolate the system before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the NPT threads per the applicable installation code, and tighten to hand-tight plus the manufacturer-recommended turns without over-torquing the stainless steel case. Verify the system is fully purged and re-pressurized to rated test pressure before returning 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 15 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1% of scale\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\u003eMount Type\u003c\/strong\u003e: Lower\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: Stainless Steel (Grade 304\/316)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBourdon Tube Material\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CRN, IP54, IP65\/NEMA 4, PED, RoHS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1009\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 83169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51540747125042,"sku":"83169","price":224.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04c8500bd6d20bc7c8570d4a801337d7.jpg?v=1785863475","url":"https:\/\/voomisupply.com\/products\/ashcroft-83169-pressure-gauge-0-15-psi-3-5in-dial-lower-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
