It is designed to close off the end of a threaded pipe run in plumbing, mechanical, and industrial piping systems. The galvanized finish provides corrosion resistance for use in exposed or moderately harsh environments. Sized at 1 inch nominal, this cap threads directly onto the male end of a pipe to seal the line against pressure or to cap unused branch connections. Licensed plumbers, pipefitters, and mechanical contractors typically install this fitting during new construction, system modifications, or piping repairs.\u003c\/p\u003e\n\u003cp\u003eThis pipe cap is suited for residential and commercial plumbing, fire protection, and general industrial pipe work where a 150 lb malleable iron threaded fitting is required. It performs well in water, air, and low-pressure steam applications that call for a standard NPT threaded closure. The galvanized coating makes it a practical choice where some moisture exposure is expected. It is commonly used to terminate unused outlets, cap test ports, or seal branch lines during phased construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch nominal size fits standard 1 inch male NPT threaded pipe ends\u003c\/li\u003e\n  \u003cli\u003eFNPT end style for straightforward wrench-tightened installation\u003c\/li\u003e\n  \u003cli\u003e150 lb pressure rating suits a wide range of low-to-medium pressure service applications\u003c\/li\u003e\n  \u003cli\u003eMalleable iron construction provides durability and thread integrity under torque\u003c\/li\u003e\n  \u003cli\u003eGalvanized finish offers corrosion resistance in wet or outdoor-adjacent environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fitting for 1 inch nominal threaded pipe systems using 150 lb malleable iron fittings with NPT connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the service type. Shut off and depressurize the pipe system fully before removing or installing any threaded cap. Apply appropriate thread sealant or PTFE tape to the male pipe threads before threading the cap on by hand, then tighten with a pipe wrench to achieve a leak-free seal. Do not over-torque, as this can crack the fitting or damage threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female NPT)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Malleable Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFigure Number\u003c\/strong\u003e: FIG 3124\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: SIGMA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 819900606\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIGMA","offers":[{"title":"Default Title","offer_id":51525348884786,"sku":"GALCAP1I-LF","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa1802033e6c6c0f3bcad235ff4192d0_a183dbb8-ce37-4065-b0f9-601993bb6ad9.jpg?v=1785471223","url":"https:\/\/voomisupply.com\/products\/sigma-819900606-malleable-iron-pipe-cap-1-in-fnpt-150-lb","provider":"Voomi Supply","version":"1.0","type":"link"}
