Manufactured from Grade 304\/304L stainless steel using a welded construction, this nipple carries a Schedule 40 wall thickness and a 1\/4 inch pipe thread size. It is a standard fitting used by plumbers, pipefitters, and mechanical contractors to extend or connect piping runs. The 304\/304L dual-grade designation makes it suitable for both standard and low-carbon applications, providing good weldability and resistance to intergranular corrosion after welding or heat exposure.\u003c\/p\u003e\u003cp\u003eThis pipe nipple is suited for residential and commercial plumbing, HVAC piping, industrial process lines, and similar applications where stainless steel fittings are specified. The 1\/4 inch size is commonly found in instrument piping, chemical feed lines, compressed air systems, and low-flow fluid distribution. It fits standard NPT pipe systems at the 1\/4 inch nominal pipe size. Installers working in corrosive or high-humidity environments often specify Grade 304 stainless over galvanized or black iron fittings to extend service life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 304\/304L stainless steel construction for corrosion resistance in wet or chemically active environments\u003c\/li\u003e\n\u003cli\u003eWelded construction with Schedule 40 wall thickness for reliable pressure-rated performance\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT thread size compatible with standard pipe fittings and valves\u003c\/li\u003e\n\u003cli\u003eDual-grade 304\/304L rating supports post-weld applications without sensitization concerns\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.076 pounds, minimizing added load in tight piping assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for standard NPT piping systems using 1\/4 inch nominal pipe size at Schedule 40 wall thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or pipefitter following applicable IPC or ASME B31 piping codes. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Use a thread sealant or PTFE tape rated for stainless steel NPT connections to prevent galling and ensure a leak-free joint. Avoid using pipe wrenches that can deform the fitting walls on light-schedule stainless nipples.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 304 \/ 304L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Welded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.076 pounds\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: 4004-250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT BRASS","offers":[{"title":"Default Title","offer_id":51700669153586,"sku":"4004-250","price":63.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe5148fc8e9f2c465bb28cd03cf474ce.jpg?v=1788393557","url":"https:\/\/voomisupply.com\/products\/merit-brass-4004-250-ss-pipe-nipple-1-4-in-sch-40-304","provider":"Voomi Supply","version":"1.0","type":"link"}
