The 40mm White Solvent Weld 45 Waste Pipe Bend is a commercial-grade plumbing fitting engineered for permanent directional changes in residential and domestic wastewater systems. Designed with dual female sockets to seamlessly connect two standard 40mm (1.5 inch) waste pipes at a clean 45-degree angle, this non-adjustable knuckle bend is injection-molded from premium, high-impact polyvinyl chloride (PVC). Built specifically for solvent weld application, it forms an absolute, permanent molecular fusion when treated with standard PVC solvent cement to prevent long-term joint degradation. Its smooth internal wall structure is optimized for superior fluid dynamics, reducing flow resistance and preventing grease, sediment, or lint accumulation in concealed under-floor or behind-wall utility drainage systems.
