Constructed from 304 and 304L stainless steel, this union offers solid corrosion resistance across a wide range of fluids and environments. It carries a 3,000 psi pressure rating, making it appropriate for moderate- to high-pressure service lines. Both end connections are FNPT, joining two female-threaded pipe ends through the union body. Licensed plumbers and pipefitters are the typical installers in commercial, industrial, and mechanical system applications.\u003c\/p\u003e\u003cp\u003eThis union is suited for use in tight-diameter instrument lines, pneumatic controls, and low-flow process piping where 1\/8 inch NPT connections are standard. The 304 and 304L dual-grade material designation makes it compatible with mildly corrosive media and sanitary-adjacent environments. It is commonly specified in mechanical rooms, process panels, and equipment skids where stainless fittings are required by design or code. The compact size suits gauge connections, bleed ports, and pilot lines in both residential and light commercial mechanical systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e304 and 304L stainless steel construction for corrosion resistance in demanding service environments\u003c\/li\u003e\n\u003cli\u003e3,000 psi pressure rating suitable for moderate- to high-pressure threaded systems\u003c\/li\u003e\n\u003cli\u003eFNPT x FNPT end connections for straight in-line installation between two threaded pipe ends\u003c\/li\u003e\n\u003cli\u003eThreaded union design allows full disassembly of a pipe run without cutting or unthreading adjacent fittings\u003c\/li\u003e\n\u003cli\u003e1\/8 inch fitting size for instrument lines, pilot lines, and gauge ports\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 1\/8 inch FNPT threaded stainless steel piping systems operating within the 3,000 psi pressure rating of this union.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter in accordance with applicable piping codes such as the IPC or ASME B31 standards. Shut off and depressurize the system fully before removing or installing any union fitting. Apply thread sealant or PTFE tape to male threads per the system fluid and code requirements. Do not over-tighten stainless NPT fittings, as galling of the threads can occur with stainless-to-stainless connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 and 304L Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5952 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: 3487D-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51539449086258,"sku":"3487D-02","price":41.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/713130a02a82ef00632d99dd13f3c1c3.jpg?v=1785840499","url":"https:\/\/voomisupply.com\/products\/merit-brass-3487d-02-pipe-union-1-8-in-304-ss-fnpt-3000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
