These PVC blanking plug end caps give plumbers, contractors, and serious DIYers a clean, watertight solution that installs in seconds and holds reliably for the long term. Each piece is a solid PVC end cap stopper sized to fit standard drain and waste pipe outer diameters. Available in four sizes — 50mm (≈2"), 75mm (≈3"), 110mm (≈4-3/8"), and 160mm (≈6-1/4") — and sold in pack sizes from 1 to 50 pieces to suit single repairs or larger projects. The smooth socket bore accepts standard PVC and uPVC pipe ends for a snug push-fit or solvent-weld installation. Typical applications include capping unused branch connections on soil stacks, sealing drain pipe ends during construction rough-in, pressure-testing DWV (drain-waste-vent) systems before inspection, and permanently closing off decommissioned drain lines in residential and light commercial plumbing. 🔵 Compatibility: Designed for standard PVC and uPVC drain & waste pipes. Fits nominal OD sizes: 50mm (≈2"), 75mm (≈3"), 110mm (≈4-3/8"), 160mm (≈6-1/4"). Compatible with common drainage standards including ASTM D2665-equivalent pipe. Not intended for pressurized supply lines — contact us to confirm if your application is non-standard. ✅ Key Features of These PVC Blanking Plug End Caps 🔒 Watertight Seal — The smooth socket bore creates a close-tolerance fit against standard pipe ODs, preventing water ingress, sewer gas escape, and debris entry when used as a drain pipe end cap stopper. 🔧 Push-Fit or Solvent-Weld Installation — Works as a temporary push-fit cap during construction or as a permanent solvent-welded fitting — no special tools required for either method, making it practical for DIY drain pipe capping jobs. 📐 Four Sizes for Common Drain Lines — Covers the most frequently used residential and light commercial drain pipe diameters: 50mm, 75mm, 110mm, and 160mm, so you can match the cap to your existing waste pipe without adapters. 🌧️ Moisture and Chemical Resistant PVC — PVC construction resists moisture, mild household chemicals, and biological growth typically found in drain and waste pipe environments, making it suitable for both indoor and outdoor drainage capping applications. 📦 Flexible Pack Sizes — Available in 1, 2, 5, 10, 20, or 50-piece packs so you can order exactly what you need — whether it's a single repair cap or a bulk supply for a multi-unit plumbing rough-in project. ⚖️ Lightweight and Easy to Handle — The low-mass PVC body makes these end caps easy to transport, store, and install in tight spaces such as wall cavities, under-slab penetrations, and confined utility chases where larger fittings are awkward to maneuver. 📐 Technical Specifications — PVC Drain Pipe Blanking Plug End Cap Product Type PVC Blanking Plug / End Cap / Pipe Stopper Material PVC (Polyvinyl Chloride) Available Sizes 50mm (≈2") / 75mm (≈3") / 110mm (≈4-3/8") / 160mm (≈6-1/4") Pack Options 1 / 2 / 5 / 10 / 20 / 50 pieces Fitting Type Push-fit or solvent-weld socket end cap Compatible Pipe Type Standard PVC / uPVC drain and waste pipe Pressure Rating Suitable for gravity-fed drain systems; contact us to confirm for pressurized applications Color / Finish See variant options Wall Thickness See variant options Application Drain pipe capping, DWV pressure testing, construction rough-in, pipe decommissioning Country of Origin Contact us to confirm ⚠️ Note: Always measure your pipe's actual outer diameter before ordering. Nominal pipe size and actual OD can vary by pipe schedule and manufacturing standard. If you are unsure which size fits your pipe, contact us before purchasing. ❓ Frequently Asked Questions How do I choose the right size PVC blanking plug for my drain pipe? Match the plug size to your pipe's actual outer diameter (OD), not the nominal pipe size label. Common US residential drain pipe ODs: 50mm (≈2") for sink, shower, and appliance drain lines; 75mm (≈3") for some branch and toilet lines; 110mm (≈4-3/8") for main toilet waste and soil stacks; 160mm (≈6-1/4") for main sewer connections and large-diameter drainage runs. Always measure with calipers or a tape measure before ordering. Can these PVC end caps handle water pressure? These blanking plugs are designed for gravity-fed drain and waste pipe systems (DWV). They are generally suitable for low-pressure applications such as capping unused drain outlets, pressure-testing pipework during inspection, or sealing temporary openings. For pressurized supply lines, please contact us to confirm suitability before ordering. Are these pipe stoppers suitable for outdoor or underground installation? PVC is generally resistant to moisture, mild chemicals, and moderate UV exposure, making it suitable for most outdoor drainage capping applications. For prolonged direct sunlight exposure, consider painting the fitting or using a UV-stabilized variant. For underground installations, PVC typically performs well in most soil conditions — verify local plumbing code requirements for buried fittings in your area. What pipe standards are these blanking plugs compatible with? These end caps are designed to fit standard PVC and uPVC drain and waste pipes. They are generally compatible with pipes conforming to common US and international drainage standards (such as ASTM D2665 or equivalent). If you are working with a specific pipe schedule, SDR rating, or non-standard OD, please contact us to confirm compatibility before ordering. Do I need solvent cement to install these end caps? For a permanent, watertight seal, PVC solvent cement (pipe cement) is generally recommended and follows standard plumbing practice. For temporary applications — such as capping a pipe during construction rough-in or pressure-testing before inspection — a push-fit installation without cement is typically sufficient. Always follow local plumbing code requirements for your specific application. Which size fits a standard US toilet waste pipe or soil stack? In most US residential plumbing, toilet waste pipes and soil stacks are typically 3" or 4" nominal diameter. The 110mm (≈4-3/8") end cap generally fits standard 4" PVC drain pipe, and the 75mm (≈3") fits standard 3" pipe. Always verify your pipe's actual outer diameter before selecting — nominal size and actual OD can differ depending on the pipe schedule. Can I remove and reuse these blanking plugs after installation? If installed push-fit only (without solvent cement), these plugs can generally be removed and reused. Once solvent-welded, removal typically requires cutting the fitting out of the pipe. For temporary capping during construction or testing, avoid using cement so the plug remains removable for later connection. 🛒 Select your size and pack size above, then add to cart — ships from our US warehouse.
