This valve features a 1\/2 inch NPTF female inlet connection and a 5\/8 inch flare outlet connection, making it compatible with a wide range of residential and light commercial plumbing configurations. It is rated to handle pressures up to 425 PSI, giving installers and service technicians reliable performance across demanding applications. Pressure reducing valves like the A15504-425 are essential components in water supply lines, refrigeration systems, and HVAC installations. They protect downstream equipment and piping from excessive inlet pressure that could cause damage, leaks, or premature component failure. Plumbers, HVAC technicians, and mechanical contractors rely on PRVs to maintain consistent, safe operating pressure throughout a system. The NPTF thread designation indicates a dry-seal tapered pipe thread, which creates a leak-resistant connection without relying solely on thread sealant. The 5\/8 inch flare outlet provides a secure, vibration-resistant connection commonly used in copper tubing systems. Mueller Streamline is a well-established manufacturer in the plumbing and HVAC supply industry, known for producing fittings, valves, and flow control components that meet the standards trade professionals expect. This valve ships as a single unit and is suited for direct replacement or new installation work. Whether you are upgrading an aging pressure regulator, completing a service call, or building out a new water distribution system, the A15504-425 delivers the flow control and pressure management performance the job requires. Always verify inlet and outlet pressure ratings match your system requirements before installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1\/2 inch NPTF female inlet connection for dry-seal, leak-resistant pipe thread engagement\u003c\/li\u003e\n\u003cli\u003e5\/8 inch flare outlet connection compatible with standard copper tubing plumbing systems\u003c\/li\u003e\n\u003cli\u003eRated up to 425 PSI for demanding residential and light commercial pressure control applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Mueller Streamline A15504-425 pressure reducing valve combines a 1\/2 inch NPTF inlet with a 5\/8 inch flare outlet and a 425 PSI pressure rating, providing reliable downstream pressure control for plumbing and HVAC systems.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A15504-425\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/2 inch NPTF Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection\u003c\/strong\u003e: 5\/8 inch Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Rating\u003c\/strong\u003e: 425 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Pressure Reducing Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Size\u003c\/strong\u003e: 1 Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51120969515314,"sku":"A15504-425","price":76.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304886321.jpg?v=1777744601","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-a15504-425-pressure-reducing-valve-1-2-inch-nptf-x-5-8-inch-flare-425-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
