Both end connections are female threaded, allowing direct makeup to standard male-threaded pipe. Rated at 150 pounds pressure and conforming to ASTM A197\/A197M, this fitting handles system temperatures up to 550 degrees F. It meets ANSI\/ASME B16.3 dimensional standards and carries UL\/FM listings, making it suitable for installations where listed components are required. Plumbers, pipefitters, and mechanical contractors install this fitting in low-pressure piping systems requiring a 45-degree directional change.\u003c\/p\u003e\n\u003cp\u003eThe zmbl4507 is used in residential and light commercial piping systems where a 45-degree change of direction is needed on a 1-1\/2 inch threaded line. Common applications include natural gas distribution piping, steam condensate return lines, and general plumbing rough-in work. The black finish is standard for gas piping installations. Its UL\/FM compliance also makes it appropriate for sprinkler and fire suppression system use where listed black iron fittings are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree elbow provides a shallow directional change to reduce turbulence compared to 90-degree fittings\u003c\/li\u003e\n  \u003cli\u003eFemale threaded x female threaded end connections for standard NPT pipe makeup\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction per ASTM A197\/A197M for impact resistance and ductility\u003c\/li\u003e\n  \u003cli\u003e150 pound pressure rating suitable for low-pressure steam, gas, and water systems\u003c\/li\u003e\n  \u003cli\u003eTemperature rating of 550 degrees F supports steam and high-temperature applications\u003c\/li\u003e\n  \u003cli\u003eUL\/FM listed and compliant with ANSI\/ASME B16.3 for use in listed piping assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1-1\/2 inch NPT threaded black iron pipe systems rated at 150 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable local codes and IFGC or IPC requirements. Shut off and depressurize the system completely before cutting into any existing line or removing fittings. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before makeup. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 45 Degree Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Female Threaded x Female Threaded (NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: ASTM A197\/A197M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 550 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ANSI\/ASME B16.3, UL\/FM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead-Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ZMB\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: MATCO-NORCA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: zmbl4507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MATCO-NORCA","offers":[{"title":"Default Title","offer_id":51138463727922,"sku":"ZMBL4507","price":29.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305526546.webp?v=1778257171","url":"https:\/\/voomisupply.com\/products\/matco-norca-zmbl4507-black-malleable-iron-45-degree-elbow","provider":"Voomi Supply","version":"1.0","type":"link"}
