Elbow 3" Hub x 3" Spigot Sched-35 PVC, NDS 31P0ST (2-PACK) The NDS 31P0ST 3" Schedule 35 PVC elbow is engineered for reliable performance in non-pressurized underground sewer and drainage systems. Designed with one hub (socket) end and one spigot (insert) end, it enables secure, solvent-welded connections that resist leakage and maintain alignment under soil load. Made from rigid PVC compound, it offers excellent chemical resistance, long-term durability, and smooth interior walls that minimize flow resistance and buildup. Certified to IAPMO and NSF standards, it meets stringent health and safety requirements for wastewater conveyance in residential, commercial, and light industrial installations. Features - 3" hub x 3" spigot configuration for seamless integration into DWV (drain-waste-vent) systems - Schedule 35 (SDR 35) wall thickness provides structural strength for underground burial up to code-specified depths - Solvent-weld joint design ensures permanent, leak-resistant connections when installed with appropriate PVC cement - Smooth interior bore reduces friction loss and prevents debris accumulation - Resists corrosion, electrolysis, and biological degradation common in sewer environments - Lightweight (0.450 lb) for easy handling and rapid installation - Complies with ASTM D3212 for solvent-cemented sewer fittings - NSF/ANSI 14 and 61 certified for safe use in sanitary drainage - Suitable for gravity-flow applications with max operating pressure of 5 psi - UV-resistant formulation allows short-term outdoor storage without degradation Specifications - Brand Name: NDS - Model Name: NDS 31P0ST - Part Number: 31P0ST - Product Type: Elbow - Schedule Type: Schedule 35 (SDR 35) - Material: PVC - End 1 Type: Hub - End 1 Diameter: 3 in - End 2 Type: Spigot - End 2 Diameter: 3 in - Product Dimensions: 4.75 x 3.00 x 3.00 in - Item Weight: 0.450 lb - Maximum Pressure: 5 psi - Underground Rated: Yes - Certifications: IAPMO Certified, NSF Listed - Lead Content: Lead-Free - Country of Origin: United States - UPC: 052063464060 - Global Trade Identification Number: 00052063464060 - Manufacturer: NDS Product Application This 3" PVC elbow is used by plumbers, contractors, and municipal crews in gravity-fed sanitary sewer, storm drainage, and building drain systems?particularly where directional changes are needed beneath slabs, in trenches, or within utility corridors. Its hub-spigot design allows rapid, code-compliant assembly in residential subdivisions, multi-family developments, and retrofit projects without mechanical joints or gaskets. Commonly installed in connection with 3" PVC sewer pipe for toilet drains, main building sewers, and septic tank inlets, it performs reliably in backfilled trenches subject to moderate soil loading. The IAPMO and NSF listings ensure acceptance by inspectors for potable-water-adjacent drainage and health-sensitive installations, while the Schedule 35 wall provides cost-effective durability without over-engineering for non-pressurized service.
