The NPT 316 Hex Nipple is built for exactly these high stakes conditions,-joining two female threaded fittings, extending pipe runs, and keeping critical systems sealed tight where lesser fittings would corrode and fail. At its core, this fitting is machined from Grade 316 stainless steel, a high performance marine alloy that sets itself apart from standard 304 stainless through the addition of molybdenum. That single difference makes it significantly more resistant to saltwater, acids, and harsh industrial chemicals—the kind of environments found on offshore rigs, chemical processing lines, food production facilities, and water treatment plants. The NPT (National Pipe Taper) thread profile does the heavy lifting when it comes to sealing. Its tapered design causes threads to mechanically wedge together as they tighten, and when paired with a thread seal tape or compound, the result is a leak-resistant joint that holds under pressure.\u003cbr\u003e\u003cdiv\u003eThe flat hex centre section is a small but practical detail that makes a real difference on the job. A standard wrench grips it cleanly, giving you the torque needed to tighten or remove the fitting without slipping or damaging surrounding pipework—even in tight, awkward spaces.\u003c\/div\u003e\n\u003c\/div\u003e\u003cp\u003e\u003cb\u003e\u003cbr\u003eSummary: \u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUsed to join two female threaded fittings, extend pipe runs, or connect equipment in tough, corrosive environments\u003c\/li\u003e\n\u003cli\u003eNPT Thread, - Tapered American threads that bite together to form tight, leak- resistant seal when used with thread seal tape or compound\u003c\/li\u003e\n\u003cli\u003eStainless steel 316 which is a high grade marine alloy containing molybdenum that resists salt water, acids, and harsh chemicals much better than standard 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eA flat, hexagonal nut shape in the middle that lets you easily grip and turn the fitting with a standard wrench\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications: \u003c\/b\u003e\u003cbr\u003eCommon uses include;\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e Marine \u0026amp; offshore\u003c\/li\u003e\n\u003cli\u003eChemical \u0026amp; industrial pipelines, and,\u003c\/li\u003e\n\u003cli\u003eFood \u0026amp; water treatement lines \u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Flocon","offers":[{"title":"Default Title","offer_id":58650440270208,"sku":"14.NNPT.HNI.015","price":2.11,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0524\/4531\/5228\/files\/NPT_20st_20st_20316_20Hex_20Nipple_14.NNPT.HNI.015.jpg?v=1785982963","url":"https:\/\/www.flocon.co.uk\/products\/stainless-steel-npt-316-hex-nipple","provider":"Flocon Valves Pipes \u0026 Fittings","version":"1.0","type":"link"}
