The Solvent Weld 40mm Knuckle Bend 90 Degree White PWE9040W is a specialized plumbing fitting designed to redirect 40mm waste pipe runs at a sharp 90-degree angle within domestic and commercial drainage systems. Manufactured from high-grade, durable white PVC, this compact bend is engineered for tight spaces where standard radius bends cannot fit, making it ideal for cramped under-sink installations or concealed bathroom voids.
 
Featuring solvent-weld socket connections on both ends, the fitting is designed to be permanently bonded using compatible solvent cement, creating a strong, leak-free, and watertight seal. Its smooth internal bore ensures efficient wastewater discharge while minimizing the risk of debris accumulation and blockages.
 
Essential for plumbers and DIY installers navigating complex or restricted pipework layouts, this knuckle bend delivers reliable, professional-grade results. Whether you are installing a new basin waste, rerouting a kitchen sink drainage line, or completing a bathroom renovation, this component provides enduring performance and a neat, uniform appearance.
