A union fitting allows a pipe run to be disconnected without disturbing the rest of the system, making it essential for serviceability in pressurized lines. The female NPT connections on both ends thread directly onto standard NPT pipe. The 316\/316L dual-grade stainless material provides strong resistance to corrosion, including chlorides and aggressive process fluids. Plumbers, pipefitters, and industrial service technicians install this fitting in high-pressure piping systems where future disassembly access is required.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for use in residential and commercial plumbing, process piping, instrumentation lines, and fluid handling applications where stainless steel is specified for corrosion resistance. The 3,000 psi pressure rating supports demanding service conditions common in hydraulic, steam, chemical feed, and compressed gas installations. Its compact 1\/8 inch size makes it a common choice for instrument tap lines, gauge connections, and small-bore process piping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3,000 psi pressure rating supports high-pressure piping applications\u003c\/li\u003e\n  \u003cli\u003e316 and 316L stainless steel construction for superior corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for standard NPT threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch fitting size for small-bore and instrument line installations\u003c\/li\u003e\n  \u003cli\u003eUnion design allows in-line disconnection without disturbing surrounding pipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-thread OEM-style replacement or new-install union fitting for 1\/8 inch NPT threaded pipe systems requiring 316 or 316L stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of pipe unions is typically performed by licensed plumbers or pipefitters. Depressurize and drain the system fully before disconnecting or installing any union fitting. Apply thread sealant or PTFE tape rated for the service fluid and pressure before making up NPT connections. Tighten to snug-plus-turns appropriate for the fitting size per standard pipefitting practice; do not overtighten stainless steel NPT threads, as galling can damage the connection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: FNPT x FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 3,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316 \/ 316L Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175300\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: MERIT BRASS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3687D-02\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51544453775666,"sku":"3687D-02","price":47.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/713130a02a82ef00632d99dd13f3c1c3_087e7198-897c-490f-adbb-edc2163e4d9f.jpg?v=1785926994","url":"https:\/\/voomisupply.com\/products\/merit-brass-3687d-02-pipe-union-1-8-inch-316-ss-fnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
