Schedule 80 CPVC Bushings
Schedule 80 PVC Reducer Bushings
Schedule 80 CPVC bushings provide a reliable, high-performance solution for reducing pipe sizes in demanding systems. With thicker walls than Schedule 40 alternatives, they offer a higher pressure rating (up to 400 PSI at 73°F) and superior resistance to heat (up to 200°F) and chemicals. These CPVC bushings are ideal for industrial and residential plumbing systems that require long-lasting, leak-free connections between different pipe diameters.
Common types include male-female reducer bushings, straight slip bushings, and flush-end designs—each suited for specific configurations. Compared to standard PVC, CPVC delivers improved heat tolerance, making it better suited for hot water and chemical applications. At Maxx Supply, we back our broad selection of Sch 80 CPVC fittings with expert support, fast delivery, and trusted customer service.
Schedule 80 CPVC Use Cases
Schedule 80 CPVC bushings are frequently used in high-pressure and high-temperature environments, such as industrial washdown systems, HVAC piping, chemical processing plants, and food and beverage production lines. Their durability and chemical resistance make them a top choice for laboratory plumbing, irrigation systems, and water treatment setups.
These bushings simplify transitions between larger and smaller diameter pipes, especially when connecting components like valves, meters, and sensors. They are also certified to meet UL and NSF standards for use in potable water systems, making them suitable for both commercial and residential plumbing. Schedule 80 CPVC bushings are also applicable in compressed air systems under specific design conditions, offering a lightweight and corrosion-resistant alternative to metal pipe fittings.
Sizing Guidance & Compatibility
Choosing the right CPVC bushing involves matching the nominal pipe sizes you need to connect—for instance, a 2″ × 1½″ reducing bushing. Schedule 80 CPVC bushings are available in male-threaded, female-threaded, and slip-fit styles to accommodate different configurations.
It’s important to note that pressure ratings may drop as temperatures increase; consult CPVC pressure-temperature charts for guidance. Straight bushings connect pipes of the same size, while reducer bushings handle transitions between different diameters. Always confirm compatibility with your pipe system before you order.
Schedule 80 CPVC Bushing Installation
To ensure a leak-free installation, start by cleaning and drying the pipe ends. Apply CPVC primer and solvent cement according to manufacturer instructions, ensuring the bushing fits flush and is fully seated. For male-threaded bushings, use a CPVC-compatible thread sealant tape.
Support the system to account for expansion and contraction, especially in hot water lines. Avoid over-tightening fittings to reduce stress concentration areas. Use proper ventilation and PPE when working with primer and cement, and make sure to follow torque guidelines to maintain system integrity. Proper stress analysis during system design can help optimize the layout and minimize long-term strain on fittings.
Cost & Efficiency Advantages
Schedule 80 CPVC bushings offer excellent ROI by reducing the need for expensive transition fittings or valve replacements. Their chemical resistance and thermal stability contribute to fewer system failures and lower maintenance costs over time.
Many commonly used sizes are kept in stock at Maxx Supply, reducing lead times and keeping projects on track. Their leak-resistant performance also minimizes downtime and labor expenses due to unexpected repairs. Choosing the right CPVC reducer bushing helps extend the life of your overall system while maintaining a tight project budget.
