The liquid fill dampens needle vibration and protects the internal mechanism from pressure spikes and pulsation, giving a stable, readable display under dynamic operating conditions. The gauge reads from 0 to 400 psi and connects via a 1\/4 inch MIPT inlet, making it compatible with standard threaded ports found on pumps, filters, and pressure systems. Licensed tradespeople and experienced service technicians are the typical installers for this type of instrument.\u003c\/p\u003e\u003cp\u003eThe PG400L suits residential and light commercial installations where pressure readings up to 400 psi are required. Common applications include pool and spa pump systems, booster pump assemblies, irrigation manifolds, and HVAC hydronic circuits. The 1\/4 inch MIPT inlet threads directly into standard gauge ports without adapters in most configurations. It is a practical, field-ready instrument for routine service checks and permanent panel mounting alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0 to 400 psi range covers high-pressure pump and filter monitoring needs\u003c\/li\u003e\n\u003cli\u003eLiquid fill stabilizes the needle against vibration and pressure pulsation\u003c\/li\u003e\n\u003cli\u003e1\/4 inch MIPT inlet fits standard gauge ports on pumps, filters, and manifolds\u003c\/li\u003e\n\u003cli\u003eCompact design suited for both permanent installation and portable service use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install gauge for plumbing, pool, HVAC hydronic, and general fluid system applications requiring a 1\/4 inch MIPT threaded connection and a 0 to 400 psi measurement range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or pool service professional. Shut off system pressure and relieve any residual pressure in the line before removing an existing gauge or threading in a new one. Apply thread sealant tape to the MIPT threads in accordance with local plumbing code requirements before installation. Do not over-tighten the inlet fitting, as this can crack the gauge body or distort the port threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range\u003c\/strong\u003e: 0 to 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/4 inch MIPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill Type\u003c\/strong\u003e: Liquid filled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 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: AQUALINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PG400L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AQUALINE","offers":[{"title":"Default Title","offer_id":51396282941746,"sku":"PG400L","price":48.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312835020.jpg?v=1782829033","url":"https:\/\/voomisupply.com\/products\/aqualine-pg400l-liquid-filled-pressure-gauge-0-400-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
