It features a 3.5-inch analog dial with a 0 to 100 psi range and a compound scale that extends down to -30 inches Hg vacuum. The stainless steel case carries a Grade 304\/316 rating, and the Bourdon tube is 316 stainless steel for corrosion resistance. Accuracy is rated at 1 percent of full scale. The glycerin or silicone fill dampens needle vibration and protects internal components, making this gauge well suited for systems with pressure pulsation or mechanical shock. Licensed HVAC technicians, plumbers, and pipefitters are the typical installers.\u003c\/p\u003e\u003cp\u003eThis gauge fits residential and commercial applications where a reliable, vibration-resistant pressure indicator is needed. Common install scenarios include boiler systems, chilled water loops, compressed air lines, hydraulic circuits, and refrigerant recovery equipment manifolds. The lower-mount, 1\/4-inch NPT connection allows direct installation into existing pipe taps or manifold ports without additional fittings in most cases. The polycarbonate lens resists impact and provides a clear view of the dial under field conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLiquid-filled case dampens needle vibration and protects the Bourdon tube in high-pulsation systems\u003c\/li\u003e\n\u003cli\u003e316 stainless steel Bourdon tube resists corrosion from aggressive media\u003c\/li\u003e\n\u003cli\u003e304\/316 stainless steel case rated for harsh environments\u003c\/li\u003e\n\u003cli\u003e1 percent of full-scale accuracy for reliable pressure readings\u003c\/li\u003e\n\u003cli\u003eCompound scale: 0 to 100 psi and -30 to 0 inches Hg vacuum on a single dial\u003c\/li\u003e\n\u003cli\u003eMeets CRN, IP54, IP65\/NEMA 4, PED, and RoHS standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure gauge for industrial, commercial, and residential piping systems requiring a 1\/4-inch NPT lower-mount connection and a 3.5-inch dial format.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and depressurize the system fully before removing an existing gauge or threading in this unit. Apply thread sealant tape or pipe dope to the male NPT threads and hand-tighten before using a wrench to avoid cross-threading. Do not overtighten the connection, as this can crack the socket or distort the Bourdon tube.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Range\u003c\/strong\u003e: -30 to 0 inches Hg\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\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: 1\/4 inches NPT\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\u003eCase Material\u003c\/strong\u003e: Stainless Steel (Grade 304\/316)\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\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: 83227\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51540653572402,"sku":"83227","price":224.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/354cb3162489ff68ea41d248e4d39263_12f9abd2-7740-489a-b908-bb4ebe4eeef4.jpg?v=1785860967","url":"https:\/\/voomisupply.com\/products\/ashcroft-83227-pressure-gauge-0-100-psi-3-5in-dial-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
