Machined from 316 stainless steel, it provides strong corrosion resistance in demanding service environments. The plug features a 1-inch male NPTF connection and is rated for a maximum operating pressure of 11,000 psi and temperatures up to 1,000 degrees F. It is used by plumbers, pipefitters, and industrial maintenance technicians to cap or test threaded pipe ends in systems where sealing integrity under extreme conditions is required.\u003c\/p\u003e\u003cp\u003eThis plug is suited for industrial piping systems, hydraulic lines, and process piping where stainless steel is specified for corrosion resistance or sanitary requirements. The NPTF thread form provides a dry-seal connection, reducing the need for additional thread sealant in many applications. Typical installs include capping unused ports on manifolds, pressure test points, and high-pressure hydraulic or pneumatic fittings in both commercial and industrial settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e316 stainless steel construction for excellent corrosion resistance in harsh or wet environments\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 11,000 psi for high-pressure system compatibility\u003c\/li\u003e\n\u003cli\u003eRated to 1,000 degrees F for high-temperature service\u003c\/li\u003e\n\u003cli\u003eMale NPTF dry-seal thread form for reliable pressure-tight connections\u003c\/li\u003e\n\u003cli\u003e1-inch connection size fits standard NPT pipe and fittings\u003c\/li\u003e\n\u003cli\u003eHollow hex head design allows engagement with standard hex or socket drive tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or add-on fitting for industrial and commercial piping systems using 1-inch female NPTF-threaded ports, including hydraulic, pneumatic, and process fluid applications requiring 316 stainless steel construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter or plumber following applicable codes such as the IPC or ASME B31 piping standards. Depressurize and isolate the line completely before removing or installing any pipe plug. Use a properly sized hex or socket drive tool to engage the hollow hex head and avoid rounding the fitting. Apply thread sealant or PTFE tape as appropriate for the service medium, unless the NPTF dry-seal thread form provides adequate sealing for the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 11,000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 1,000 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SS5406-HHP-16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67949566755122,"sku":"SS5406-HHP-16","price":30.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe6d6c3ef96e9e27c3067496937c3f57_fe7b2bd0-7781-4242-a607-3b39414a2354.jpg?v=1791695160","url":"https:\/\/voomisupply.com\/products\/midland-industries-ss5406-hhp-16-hollow-hex-head-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
