This valve features a 1\/4 inch nominal size with NPTFE x Flared end connections, making it compatible with a wide range of copper tubing and threaded pipe configurations commonly found in residential and commercial installations. The brass body construction provides excellent corrosion resistance and long-term durability, even in demanding service environments. A pressure relief valve like this one serves a fundamental role in any pressurized system. When system pressure exceeds a safe threshold, the valve opens automatically to release excess pressure, protecting equipment, piping, and personnel from damage or injury. The b33752-425 is rated to handle pressures from 150 to 700 psi, giving technicians a broad operating range suitable for a variety of refrigerant and fluid systems. The temperature rating spans from -40 to 300 degrees Fahrenheit, covering both low-temperature refrigeration applications and higher-temperature hydronic or steam-adjacent systems. The straight-thru design allows for straightforward inline installation without redirecting flow, which simplifies system layout and reduces installation time. At 2.81 inches in width, this compact valve fits in tight mechanical spaces where larger components would not. HVAC technicians, refrigeration mechanics, and plumbers rely on SafetyMaster pressure relief valves for their consistent performance and code-compliant pressure protection. Whether you are servicing a refrigeration circuit, a hydronic heating loop, or a compressed air line, this valve delivers reliable overpressure protection. The NPTFE x Flared connection style ensures a secure, leak-resistant seal on both the threaded and flared sides of the connection, reducing the risk of refrigerant or fluid loss at the fitting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrass body construction resists corrosion and withstands demanding service conditions\u003c\/li\u003e\n\u003cli\u003eWide pressure range of 150 to 700 psi suits diverse HVAC, refrigeration, and plumbing applications\u003c\/li\u003e\n\u003cli\u003eNPTFE x Flared end connections provide secure, leak-resistant installation with copper tubing systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Mueller Streamline b33752-425 SafetyMaster Straight Thru Pressure Relief Valve offers broad pressure and temperature ratings in a compact brass body, making it a reliable choice for trade professionals who need dependable overpressure protection in HVAC, refrigeration, and plumbing 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: b33752-425\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: NPTFE x Flared\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 to 700 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -40 to 300 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.81 inches\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51121089642802,"sku":"B33752-425","price":107.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304886331.jpg?v=1777748088","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-b33752-425-safetymaster-straight-thru-pressure-relief-valve-1-4-inch-nptfe-x-flared-brass-body","provider":"Voomi Supply","version":"1.0","type":"link"}
