Made for use on drain, waste, and vent (DWV) piping systems, this cap slips over the pipe end and cinches down to form a reliable seal. Plumbers and pipefitters rely on this type of cap when pressure-testing new or existing plumbing rough-ins before final inspection. The flexible construction allows it to seat securely on pipe ends without rigid couplings or threaded fittings.\u003c\/p\u003e\u003cp\u003eThe PQC-104 is suited for residential and light commercial plumbing applications where temporary pipe closure is required during rough-in testing or system commissioning. It is used on 4-inch pipe ends in DWV systems, including ABS, PVC, and cast iron configurations where a test cap is needed for air or water pressure testing prior to inspection sign-off.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFits 4-inch pipe openings for temporary sealing during pressure and leak tests\u003c\/li\u003e\n\u003cli\u003eFlexible design accommodates standard pipe end tolerances\u003c\/li\u003e\n\u003cli\u003eNo threading or rigid couplings required for installation\u003c\/li\u003e\n\u003cli\u003eSold in a package quantity of 20 units per case\u003c\/li\u003e\n\u003cli\u003eLightweight construction suitable for field use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard test cap for 4-inch DWV piping systems in residential and commercial plumbing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed plumbers during rough-in or pre-inspection testing phases. Shut off all water supply and relieve system pressure before removing or repositioning any test caps. Follow local plumbing code requirements, including IPC guidelines, for test pressure limits and duration. Do not exceed the rated pressure capacity of the cap or use it as a permanent pipe closure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 20 EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14 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: FERNCO INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PQC-104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FERNCO","offers":[{"title":"Default Title","offer_id":51524378526002,"sku":"PQC-104","price":104.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/078f5bef67b8a23ebf0445c7ec053f38.jpg?v=1785447478","url":"https:\/\/voomisupply.com\/products\/fernco-inc-pqc-104-qwik-cap-flexible-test-cap-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
