This fitting connects branch lines to main drainage runs using a tool-free snap-in installation method. The corrugated HDPE construction provides flexibility and resistance to soil movement, making it well suited for subsurface drainage systems. Plumbers and drainage contractors install this fitting as part of stormwater management, foundation drainage, and agricultural runoff systems. The snap-fit design reduces labor time on the job site by eliminating the need for adhesives or mechanical fasteners.\u003c\/p\u003e\u003cp\u003eThis snap tee is used in single-wall corrugated drainage pipe systems typically installed below grade. Common applications include yard drainage, French drain installations, downspout tie-ins, and perimeter foundation drainage. The 4-inch size is one of the most widely used dimensions in residential and light commercial drainage layouts. This fitting is appropriate for gravity-flow drainage lines where a branch connection is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter compatible with single-wall corrugated HDPE pipe\u003c\/li\u003e\n\u003cli\u003eSnap-fit connection requires no adhesives or mechanical fasteners\u003c\/li\u003e\n\u003cli\u003eHDPE material resists corrosion, chemicals, and soil movement\u003c\/li\u003e\n\u003cli\u003eCorrugated profile provides flexibility for below-grade installation\u003c\/li\u003e\n\u003cli\u003eTee configuration allows branch connections in drainage runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for 4-inch single-wall corrugated HDPE drainage pipe systems used in residential and light commercial subsurface drainage applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by plumbers or drainage contractors working on subsurface drainage systems. Ensure the main pipe run is clear of debris and properly bedded before seating the snap tee. The snap-fit connection should be fully seated and audible before backfilling. Follow local plumbing codes and manufacturer guidelines for burial depth and bedding material requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: HDPE (High-Density Polyethylene)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Type\u003c\/strong\u003e: Single-Wall Corrugated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Snap Tee\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder Increment\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ADVANCED DRAINAGE SYSTEMS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 421 AA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ADVANCED DRAINAGE SYSTEMS","offers":[{"title":"Default Title","offer_id":51396349985074,"sku":"421 AA","price":25.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312834443.jpg?v=1782829951","url":"https:\/\/voomisupply.com\/products\/advanced-drainage-systems-421-aa-4-in-hdpe-snap-tee","provider":"Voomi Supply","version":"1.0","type":"link"}
