PVC reducer coupling 3 to 2 is a pipe fitting used to connect PVC pipes of different diameters, and is widely applied in water supply and drainage systems, agricultural irrigation, industrial fluid transportation, as well as ventilation and sewage systems.
PVC Reducer Coupling 3-to-2 Construction and Material Features
This reducer is made directly from high-quality polyvinyl chloride (PVC) with excellent chemical stability and mechanical strength. PVC is highly resistant to corrosion from acids, alkalis, and salts, and will not rust or scale, making it ideal for use in water supply, drainage, and industrial fluid piping systems. Its smooth internal surface provides low fluid resistance, maintaining stable flow and reducing energy consumption.
The 3-to-2 PVC reducer coupling typically features a two-ended spigot design and can connect to corresponding 3-inch and 2-inch PVC pipes. The appearance color is usually light gray or white, and it complies with standards such as ASTM D2466 and SCH 40. It has good strength and maintains low weight, making it easy to carry and install.
Key Dimensions and Technical Specifications
This product has an inner diameter of 3 inches (approximately 89 mm) on one end and 2 inches (approximately 60 mm) on the other. The diameter change is achieved through a smooth transition design, ensuring smooth flow during the reduction process.
Compatible pipe materials: SCH 40 or SCH 80 PVC pipe
Connection method: Solvent weld or spigot
Pressure rating: Approximately 150 PSI (at room temperature)
Color: Gray or white
Operating temperature: Recommended operating temperature: 0°C to 60°C
These specifications make this product highly versatile and reliable in domestic plumbing, agricultural, and industrial systems.
Installation and Instructions
The 3″ to 2″ PVC reducer coupling is easy to install and can be connected using solvent weld. The procedure is as follows:
Clean the inside of the pipe and fitting at both ends to ensure they are free of dust and oil.
Evenly apply PVC solvent-based adhesive to the connector.
Quickly insert the pipe and rotate it 1/4 turn, holding for a few seconds to ensure even distribution.
Let the adhesive cure for several minutes before use.
This connection provides a strong seal and will not leak due to vibration or pressure fluctuations.
Product Advantages
Corrosion Resistance: PVC material resists corrosion from a wide range of chemicals and offers a long service life.
Lightweight and High-Strength: Lighter than metal fittings, making them easier to transport and install while maintaining a sturdy and reliable structure.
Smooth Interior: Reduces water flow resistance and improves conveying efficiency.
Insulation and Rust-Resistant: Non-conductive and rust-resistant, making it particularly suitable for humid environments.
Easy Maintenance: No preservative treatment is required, resulting in low ongoing maintenance costs.
Economical and Practical: Relatively affordable, offering a high cost-effectiveness, making it suitable for large-scale projects.
PVC Reducer Coupling 3 to 2 Applications
PVC Reducer Coupling 3″ to 2″ is widely used in:
