Sewer/Drain Street Elbow 45 4" Hub X 4" D Spigot Schd-35 PVC, NDS 4P03ST 2-PK The NDS 4P03ST 4-inch PVC 45 street elbow is a precision-molded, schedule 40 drainage fitting designed for seamless, solvent-weld connections in non-pressure sewer and drain (S D) systems. Featuring a hub end for socket-style connection to 4-inch S D pipe and a spigot end for insertion into another 4-inch fitting, it enables a smooth 45-degree directional change in gravity-fed drainage networks ? ideal for connecting channel drains, pop-up emitters, dry wells, or grates to main sewer lines. Constructed from rigid, UV-stabilized white PVC per ASTM D2729, D3034, D2751, F810, and D2665 standards, it resists corrosion, chemical degradation, and environmental stress while maintaining structural integrity over decades of use. Features - 45 angle design provides optimal flow transition with reduced turbulence and clogging risk - Hub-to-spigot configuration enables direct, solvent-weld connection between two 4-inch S D components - Compatible with NDS and other ASTM-compliant 4-inch S D pipe and fittings - Rigid white PVC construction resists cracking, UV damage, and chemical exposure - Designed for use in non-pressurized drainage, sewer, and stormwater systems only - Solvent-weld joint creates a permanent, watertight seal without gaskets or clamps - Smooth interior bore ensures unobstructed flow and easy cleaning - Lightweight at 4.8 oz (0.14 kg) for easy handling and transport - White finish blends with standard PVC drainage systems for a clean, uniform appearance - Meets or exceeds ASTM D2665 (DWV) and D2729 (S D) standards for performance and safety - Ideal for residential, commercial, and municipal stormwater and subsurface drainage installations Specifications - Brand Name: NDS - Model Name: NDS 4P03ST - Product Type: 45 Street Elbow - Material: PVC (Schedule 40) - Color: White - Connection Type: Hub x Spigot - Nominal Size: 4 in - Angle: 45 - Pipe Compatibility: 4 in Sewer Drain (S D) Pipe and Fittings - Standards Compliance: ASTM D2729, D3034, D2751, F810, D2665 - Pressure Rating: Non-Pressure (Gravity Flow Only) - Temperature Rating: Suitable for ambient drainage applications - Weight: 4.8 oz (0.14 kg) - Dimensions: 5.5x4.5x6.25 in (LxWxH) - Quantity: 1 pc per pack - Packaging: Retail Packaged - Country of Origin: United States - UPC: 052063484037 - GTIN: 00052063484037 - Part Number: 4P03ST - Manufacturer: NDS, Inc. Product Application The NDS 4P03ST 45 street elbow is used by landscape contractors, civil engineers, and drainage installers connecting components of stormwater and subsurface drainage systems ? including channel drains, dry wells, pop-up emitters, and catch basins ? to 4-inch S D piping. Its 45-degree angle provides a gentle, efficient flow path that reduces sediment buildup and minimizes the risk of blockages compared to sharper turns. Commonly installed in residential developments, commercial properties, and public infrastructure projects, it ensures code-compliant, long-lasting performance in gravity-fed applications. Professionals rely on its durable PVC construction and reliable solvent-weld fit to deliver seamless integration, watertight seals, and trouble-free operation ? providing the confidence that drainage systems remain functional, efficient, and maintenance-free for years.
