features nipplesMaterials Used in Production

Sch 80 CPVC nipples are made from a high-strength compound called chlorinated polyvinyl chloride (CPVC). This material is known for its excellent chemical resistance, high-temperature handling capability, and durability. CPVC is a thermoplastic that can withstand various chemicals, including acids, alkalis, and solvents, making it suitable for use in various industries.

Production Process

The production of Sch 80 CPVC nipples involves several steps to ensure their quality and reliability. The CPVC material is first compounded, where additives are mixed with the base resin to enhance its properties.

The compound is then extruded into pipe form, cut into desired lengths, and further machined to add the male threads on both ends. Strict quality control measures are followed throughout the production process to ensure that the resulting nipples meet industry standards.

Design Characteristics

Sch 80 CPVC nipples have a unique design that facilitates easy installation and provides a secure connection between pipes. The male threads on both ends allow for a tight fit when connected to fittings with female threads. The nipple’s length can vary depending on the specific application requirements. Additionally, the smooth interior of the nipple ensures optimal flow of liquids and reduces the risk of clogs or blockages.

Size Variations

Sch 80 CPVC nipples are available in a range of sizes to accommodate different piping systems and applications. The sizes typically range from ½ inch to 2 inches in diameter, with varying lengths to suit specific installation needs. Selecting the appropriate size based on the pipe diameter and the liquid’s flow rate is important.


One of the major advantages of using Sch 80 CPVC nipples is their exceptional durability. CPVC is highly resistant to cracking, breaking, and warping, even in high-pressure and high-temperature environments. This durability ensures the longevity of the piping system and reduces the need for frequent repairs or replacements.

Resistance Against Corrosion

Sch 80 CPVC nipples offer excellent resistance against corrosion, making them suitable for use in various industries and applications. Unlike metal fittings that can corrode and deteriorate over time, CPVC nipples remain unaffected by most corrosive substances, including acids, alkalis, and salts. This corrosion resistance helps maintain the integrity of the piping system and ensures long-term reliability.

Temperature Handling Capability

Sch 80 CPVC nipples have a high temperature handling capability, allowing them to withstand both hot and cold liquids. They can safely handle temperatures up to 200°F (93.3°C) for prolonged periods without any significant impact on their structural integrity. This temperature resistance makes them suitable for use in applications involving hot water supply, industrial processes, and HVAC systems.

Compatibility with Various Liquids

Sch 80 CPVC nipples are compatible with a wide range of liquids, including water, chemicals, and various industrial fluids. CPVC is resistant to many commonly used chemicals, which ensures that the nipples will not degrade or react with the transported liquids. This compatibility makes Sch 80 CPVC nipples a versatile choice for various industries and applications.


standardsMeaning of Sch 80 Label

The “Sch” in Sch 80 stands for Schedule, which is a designation used to indicate the wall thickness of a pipe or fitting. In the case of Sch 80 CPVC nipples, the number 80 represents the thickness of the pipe walls. Sch 80 is thicker and more robust than its Sch 40 counterpart, making it suitable for applications that require higher-pressure handling and increased durability.

Comparison between Sch 40 and Sch 80

While both Sch 40 and Sch 80 are commonly used in plumbing and industrial applications, they differ in terms of wall thickness and pressure handling capabilities. Sch 40 CPVC nipples have thinner walls and are suitable for low to medium pressure applications. Sch 80 CPVC nipples, on the other hand, have thicker walls and can withstand higher pressure environments. The choice between Sch 40 and Sch 80 depends on the specific requirements of the application.

Standards of Measurements

Sch 80 CPVC nipples are manufactured according to industry standards such as ASTM D1784, ASTM F441, and NSF/ANSI 14. These standards ensure that the nipples meet the required specifications for strength, durability, and chemical resistance. It is important to ensure that the Sch 80 CPVC nipples being used comply with these standards to ensure the safety and reliability of the piping system.
