The female NPT (FNPT) end style allows it to thread directly onto male-threaded pipe ends, creating a secure, pressure-rated termination point. Manufactured from PVC, this cap is suited for use in water distribution, irrigation, chemical conveyance, and drainage systems where a clean, permanent or serviceable pipe end closure is required. Licensed plumbers and pipefitters are the typical installers, and the domestic manufacture designation indicates U.S.-sourced production.\u003c\/p\u003e\n\u003cp\u003eThis cap is appropriate for residential and light commercial plumbing, irrigation mainlines, and industrial process piping where 4-inch Schedule 40 PVC pipe is used. The FNPT thread pattern ensures compatibility with standard NPT-threaded pipe ends without requiring additional adapters. It is a common choice for capping off branch lines, pressure-test points, or unused service outlets in PVC piping systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch nominal FNPT end style threads directly onto male NPT pipe ends\u003c\/li\u003e\n  \u003cli\u003eRated for Schedule 40 and standard wall pipe systems\u003c\/li\u003e\n  \u003cli\u003ePVC construction provides corrosion resistance in wet and chemical environments\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured\u003c\/li\u003e\n  \u003cli\u003eClean termination for branch lines, test ports, or unused outlets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for 4-inch nominal Schedule 40 PVC piping systems with male NPT-threaded pipe ends.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing codes. Depressurize and drain the line completely before installing or removing any threaded cap. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before hand-tightening and then finishing with strap or pipe wrenches. Do not over-torque PVC fittings, as excessive force can crack the fitting body or damage the threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: FNPT (Female National Pipe Thread)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: SCH 40 \/ STD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: DURA PLASTIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L176750P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURA PLASTIC","offers":[{"title":"Default Title","offer_id":51524392812850,"sku":"40CAPFIP4","price":19.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/327626b3795ba5820e06278f5afbe00f.jpg?v=1785447764","url":"https:\/\/voomisupply.com\/products\/dura-plastic-l176750p-pvc-pipe-cap-4-inch-fnpt-sch-40","provider":"Voomi Supply","version":"1.0","type":"link"}
