With a 1\/2-14 thread and a 150 lb pressure class rating, this fitting locks threaded pipe assemblies in place and prevents loosening under vibration or pressure cycling. At 0.06 pounds, it is lightweight but built for demanding service. The SP-114 series construction in 316 stainless steel provides strong resistance to chloride environments, making this locknut appropriate for marine, chemical, food processing, and industrial plumbing applications. Licensed plumbers and pipefitters are the typical installers for this type of fitting.\u003c\/p\u003e\n\u003cp\u003eThis hex locknut is suited for residential and commercial piping installations where standard carbon steel or 304 stainless fittings are not sufficient for the service environment. The 316 stainless steel alloy is the preferred choice in coastal, chemical, and sanitary process piping where pitting corrosion is a concern. It fits standard 1\/2-inch NPT threaded pipe and is compatible with other SP-114 series 316 stainless fittings for consistent material specification throughout an assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for superior corrosion resistance in harsh environments\u003c\/li\u003e\n  \u003cli\u003e1\/2-14 thread matches standard 1\/2-inch NPT pipe connections\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure class rating for compatibility with standard-pressure piping systems\u003c\/li\u003e\n  \u003cli\u003eHex body profile allows standard wrench engagement for secure installation and removal\u003c\/li\u003e\n  \u003cli\u003ePart of the SP-114 316 SS fittings series for consistent material matching across assemblies\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.06 pounds, suitable for overhead or weight-sensitive installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-inch NPT threaded pipe and compatible with other SP-114 series 316 stainless steel fittings.

Ensure the mating pipe and fittings are fully depressurized and drained before making any threaded connections or adjustments. Use appropriate thread sealant or tape rated for stainless steel and the intended service fluid. Apply wrench force to the hex body only  -  do not grip the threads directly  -  and follow applicable IPC or IFGC code requirements for the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Class\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP-114\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63703MS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67951895150898,"sku":"63703MS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/551aa8c4c35dcad0377668cba8c36600_2f73bea4-3592-4ec8-9626-9404411d28aa.jpg?v=1791740339","url":"https:\/\/voomisupply.com\/products\/midland-industries-63703ms-hex-locknut-1-2-in-316-ss-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
