It reads dual scales of 0 to 35 inches water column (inches WC) and 0 to 20 ounces per square inch, making it well suited for natural gas and LP gas pressure verification during commissioning and service. The gauge features a 2.5-inch dial face for clear readability and a 0.25-inch male pipe thread (MPT) lower-mount connection. HVAC technicians and gas service professionals rely on this type of gauge when checking appliance inlet pressure, regulator output, and manifold pressure on heating equipment.\u003c\/p\u003e\u003cp\u003eThis gauge is intended for low-pressure gas service applications common in residential and light commercial settings. Typical use cases include verifying gas supply pressure at furnaces, boilers, water heaters, and other gas-fired appliances. The lower-mount connection allows the gauge to thread directly into a tee fitting or test port on a gas line, providing an inline reading during system diagnostics. The dual-scale display eliminates the need for unit conversion in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDual-scale readout: 0-35 inches WC and 0-20 oz per square inch on a single dial\u003c\/li\u003e\n\u003cli\u003e2.5-inch dial face for clear in-field readability\u003c\/li\u003e\n\u003cli\u003e0.25-inch MPT lower-mount connection for direct inline installation\u003c\/li\u003e\n\u003cli\u003eDiaphragm sensing element suited for low-pressure gas measurement\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits standard gas appliance test ports\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or field-service gauge for low-pressure gas applications requiring a 0-35 inches WC range with a 0.25-inch MPT lower-mount connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed gas technician or qualified HVAC professional in accordance with local codes and IFGC requirements. Shut off the gas supply and relieve line pressure before installing or removing the gauge. Use thread sealant rated for gas service on the MPT connection and verify for leaks with an approved leak-detection solution after pressurizing. Do not exceed the rated pressure range of the gauge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0-35 inches WC \/ 0-20 oz per square inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Size\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 0.25 inches MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Location\u003c\/strong\u003e: Lower Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Type\u003c\/strong\u003e: Diaphragm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService\u003c\/strong\u003e: Gas\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DWYER INSTRUMENTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dg25c-035-4l\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DWYER INSTRUMENTS","offers":[{"title":"Default Title","offer_id":51233521107250,"sku":"DG25C-035-4L","price":74.43,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/dwyer-instruments-dg25c-035-4l-gas-diaphragm-pressure-gauge","provider":"Voomi Supply","version":"1.0","type":"link"}
