This fitting transitions from a 1\/2-inch male pipe thread to a 1\/4-inch male pipe thread using standard MPT end connections on both ends. The black polypropylene construction resists corrosion, moisture, and many common chemicals, making it a practical choice where metal fittings would be subject to degradation. Licensed plumbers and pipefitters install this fitting when reducing line size between threaded pipe sections in low-pressure fluid or gas distribution runs.\u003c\/p\u003e\n\u003cp\u003eThis hex nipple is suited for residential and light commercial plumbing applications, as well as chemical processing, irrigation, and pneumatic systems where polypropylene is an approved material. The external wrench flats allow standard hex tooling for installation and removal without slipping. It is commonly used in filter housings, manifolds, and instrument connections where a compact threaded reducer is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolypropylene construction resists corrosion and chemical attack\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch to 1\/4-inch reducing hex nipple for compact inline size transitions\u003c\/li\u003e\n  \u003cli\u003eMPT end connections on both ends for standard threaded pipe assembly\u003c\/li\u003e\n  \u003cli\u003eBlack color for visual identification in multi-line installations\u003c\/li\u003e\n  \u003cli\u003eHex body profile accepts standard wrench tooling for secure installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for threaded polypropylene piping systems using standard NPT-compatible male pipe thread connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pipefitters working on threaded piping systems. Shut off system pressure and drain the line before removing or installing any threaded fitting. Apply thread sealant or PTFE tape appropriate for use with polypropylene and the specific fluid or gas being conveyed. Do not overtighten polypropylene fittings, as the material can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Nipple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/2 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: MPT (Male Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0102 pounds\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 316P-8-4PP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542258975026,"sku":"316P-8-4PP","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07a2c999bbc876a2403754d3e8905455.jpg?v=1785896604","url":"https:\/\/voomisupply.com\/products\/parker-316p-8-4pp-polypropylene-hex-nipple-1-2-x-1-4-inch-mpt","provider":"Voomi Supply","version":"1.0","type":"link"}
