A PVC Long D Joint refers to a specific type of PVC (Polyvinyl Chloride) pipe fitting that has a long or extended D-shaped structure. PVC is a common material for plumbing and pipe fittings due to its durability, corrosion resistance, and affordability. This fitting is designed to join two pipes at a 90-degree angle, and the extended D-shape allows for a longer connection than a standard D Joint. They are versatile and can be employed in various applications, including water supply lines, drainage systems, and irrigation setups. PVC Long D Joint is commonly used in plumbing systems for creating 90-degree turns or connections.
