The gauge features a 2.5-inch dial with a dual-scale display and a 0 to 100 psi range, providing a 1.5% of scale accuracy rating that meets ASME B40.100 standards. The 304 stainless steel case and brass wetted parts deliver corrosion resistance in wet or vibration-prone environments. Glycerine fill dampens needle movement and protects internal components from pressure spikes and vibration. HVAC technicians, plumbers, and mechanical contractors install this gauge as part of system monitoring, testing, and commissioning setups.\u003c\/p\u003e\n\u003cp\u003eThe PFQ804 is suited for residential and commercial HVAC systems, plumbing and hydronic heating systems, water treatment, and light industrial piping applications. The lower mount configuration with a 0.25-inch NPT connection allows direct in-line or manifold installation. The NSF-61-372 certification makes it appropriate for potable water applications. IP65-rated construction protects against dust and water ingress, extending service life in outdoor or damp mechanical room environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGlycerine-filled case dampens vibration and protects against pressure spikes\u003c\/li\u003e\n  \u003cli\u003e1.5% of scale accuracy meets ASME B40.100 requirements\u003c\/li\u003e\n  \u003cli\u003e304 stainless steel case with brass wetted parts for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eDual-scale analog dial with 2.5-inch diameter for easy field reading\u003c\/li\u003e\n  \u003cli\u003eNSF-61-372 certified for use in potable water systems\u003c\/li\u003e\n  \u003cli\u003eIP65-rated enclosure resists dust and water ingress\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new-installation pressure gauge for systems using a 0.25-inch NPT lower mount connection with a pressure range up to 100 psi.

Shut off system pressure and relieve any residual pressure before removing an existing gauge or installing a new one. Use appropriate thread sealant or PTFE tape on the NPT threads per IPC and IFGC guidelines, and avoid over-tightening to prevent case or fitting damage. Glycerine-filled gauges should be mounted in orientations that keep the lens facing up or outward to prevent air pocket formation in the case.\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 100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 1.5% of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 inches (63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Dual analog\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Lower mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: 0.25 inches NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Filled\u003c\/strong\u003e: Yes, glycerine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material\u003c\/strong\u003e: 304 stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWetted Parts Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLens Material\u003c\/strong\u003e: Polycarbonate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B40.100, CRN, IP65, NSF-61-372\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: WINTERS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PFQ804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WINTERS","offers":[{"title":"Default Title","offer_id":51721387868466,"sku":"PFQ804","price":48.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/369c0a3877364f6fee4855f3bef7c81c_8b2bbb57-c27b-4719-aa67-6f19168399db.jpg?v=1788576977","url":"https:\/\/voomisupply.com\/products\/winters-pfq804-pressure-gauge-0-100-psi-2-5in-dial","provider":"Voomi Supply","version":"1.0","type":"link"}
