When planning plumbing, irrigation, or industrial fluid transport systems, selecting the correct conduit is critical for long-term performance and reliability. The 1 1 2 PVC Pipe represents a versatile and widely used option within the broader category of Polyvinyl Chloride Pipes. This specific size is a common choice for various applications requiring a balance of flow capacity and structural integrity. Understanding standard PVC Pipe Diameters is the first step in a successful project, ensuring compatibility with system requirements. For specialized applications where visual monitoring of fluid flow is necessary, a Clear PVC Pipe variant may be available. No pipe system is complete without the proper connectors and accessories; a full range of compatible PVC Fittings is essential for creating secure, leak-free assemblies, including elbows, tees, couplings, and adapters designed specifically for this pipe size.


The 1 1 2 PVC Pipe is engineered from high-quality, durable polyvinyl chloride material, offering excellent resistance to corrosion, chemical degradation, and impact. This makes it an ideal solution for both pressurized and non-pressurized systems, including potable water distribution, drainage, and agricultural irrigation. Its smooth interior wall minimizes friction loss, promoting efficient fluid flow. The pipe is manufactured to meet or exceed industry standards for dimensional accuracy and pressure ratings, ensuring consistent performance and ease of installation.
