Filled with glycerine to dampen needle vibration and protect internal components, it features a 2.5-inch dial with a single-scale range of 0 to 100 psi and an accuracy rating of plus or minus 2.5 percent of scale. The stainless steel case and stainless steel wetted parts provide corrosion resistance in demanding service environments. A 1\/4-inch NPT lower-mount connection allows direct inline or panel installation. HVAC technicians, plumbers, and industrial service professionals install this gauge to verify system pressure during commissioning, service, and diagnostics.\u003c\/p\u003e\n\u003cp\u003eThis gauge is suited for residential and light commercial applications where reliable pressure indication is required on gas or liquid systems. The glycerine fill makes it a strong choice for installations with pump-induced pulsation or mechanical vibration that would cause an unfilled gauge to read erratically. The lower-mount NPT configuration fits standard threaded ports on piping, manifolds, and pressure test assemblies commonly found in HVAC refrigerant circuits, hydronic heating systems, water supply lines, and pool and spa equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGlycerine-filled case dampens vibration and pulsation for stable needle reading\u003c\/li\u003e\n  \u003cli\u003e0 to 100 psi single-scale range with analog dial display\u003c\/li\u003e\n  \u003cli\u003e2.5-inch dial diameter for clear readability in tight service locations\u003c\/li\u003e\n  \u003cli\u003eStainless steel case (304 grade) and stainless steel wetted parts for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT lower-mount connection for standard inline installation\u003c\/li\u003e\n  \u003cli\u003eSuitable for both gaseous and liquid media service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service gauge for gas and liquid pressure monitoring applications requiring a 1\/4-inch NPT lower-mount fitting and a 0 to 100 psi range.

Isolate and depressurize the system completely before removing an existing gauge or installing this unit into a pressurized port. Apply an appropriate thread sealant to the NPT threads per local plumbing code requirements; do not overtighten, as stainless fittings are susceptible to galling. Confirm the pressure range of the system does not exceed 100 psi before commissioning.\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: plus or minus 2.5 percent of scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.5 inches (63.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Type\u003c\/strong\u003e: Analog, single scale\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: 1\/4-inch 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: Stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Gaseous and liquid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 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: WIKA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4282918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIKA","offers":[{"title":"Default Title","offer_id":51694898151730,"sku":"4282918","price":243.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c109cad29fe1a039ecc84cdb8518b3ba.jpg?v=1788329474","url":"https:\/\/voomisupply.com\/products\/wika-4282918-pressure-gauge-0-100-psi-2-5-in-dial-lower-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
