Sized at 3\/4 inch, this union allows a plumber or pipefitter to join, disconnect, and reconnect sections of threaded pipe without rotating either pipe run. The all-brass construction resists corrosion in water and low-pressure gas service applications. It is sold and packaged as a single unit and weighs 0.72 pounds.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and light commercial plumbing, hydronic heating, and general-purpose pipe assembly where threaded connections are required. The FBSPT x FBSPT end configuration makes it compatible with standard tapered external male threads in piping systems following BSP thread standards. It is typically installed by licensed plumbers, pipefitters, or experienced mechanical contractors working on pressure pipe systems rated within Class 125 limits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClass 125 pressure rating suited for standard water and low-pressure service\u003c\/li\u003e\n\u003cli\u003eFBSPT x FBSPT threaded ends for secure, leak-resistant tapered thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/4 inch fitting size for common residential and commercial pipe runs\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance in plumbing and hydronic applications\u003c\/li\u003e\n\u003cli\u003eUnion design allows pipe disconnection without disturbing adjacent piping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install threaded union for 3\/4 inch pipe systems using BSP tapered thread standards in Class 125 rated plumbing assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing codes. Shut off the water supply and relieve system pressure fully before removing or installing any union fitting. Apply appropriate thread sealant or PTFE tape to the male threads before make-up, and do not overtighten, as brass fittings are subject to thread damage from excessive torque. Verify the system pressure rating does not exceed the Class 125 designation of this fitting before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: FBSPT x FBSPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: Class 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT BRASS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XB187-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51541059305778,"sku":"XB187-12","price":56.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e86c35a3edc309381a07964c533631bb.jpg?v=1785867977","url":"https:\/\/voomisupply.com\/products\/merit-brass-xb187-12-brass-pipe-union-3-4-in-class-125","provider":"Voomi Supply","version":"1.0","type":"link"}
