Elbow 90° Plain refers to a plumbing fitting made of Polyvinyl Chloride (PVC) material, designed with a 90-degree angle to change the direction of a PVC pipe by 90 degrees. The term “plain” typically indicates that the elbow does not have any threads or connections on its ends; it is smooth and meant to be solvent-welded or glued to the PVC pipes.
Here’s what each part of the term means:
PVC: Polyvinyl Chloride is a synthetic plastic polymer widely used in plumbing and construction due to its durability, affordability, and resistance to corrosion and chemical damage.
Elbow: In plumbing, an elbow is a fitting that allows for a change in the direction of the flow of water or other fluids in a pipeline. The 90-degree angle indicates that it makes a sharp turn, shifting the flow by 90 degrees.
90: The number “90” signifies the angle of the elbow, in this case, 90 degrees. Elbows are available in various angles, such as 45 degrees, 22.5 degrees, etc., to suit different plumbing configurations.
Plain: The term “plain” means that the elbow does not have any threaded connections. Instead, it requires the use of PVC solvent cement or glue to join it securely to PVC pipes.
These PVC 90-degree plain elbows are commonly used in various plumbing applications, such as water supply lines, drainage systems, irrigation systems, and more. They come in different sizes to fit different pipe dimensions, and their smooth, plain ends allow for a strong, leak-resistant bond when properly solvent-welded.
