Product Knowledge

In most cases, a male elbow PP compression fitting is designed to handle both hot and cold water in plumbing applications. Polypropylene (PP) is known for its good thermal resistance, which allows PP compression fittings to be used with water at various temperatures. However, there are a few factors to consider:
Material Grade: Different grades of PP might have varying temperature resistances. PP-R (Polypropylene Random) is often used for hot and cold water applications due to its enhanced temperature resistance compared to PP-H (Polypropylene Homopolymer).
Temperature Range: Check the manufacturer's specifications to ensure that the male elbow PP compression fitting can handle the temperature range of your hot and cold water supply. PP-R fittings are typically suitable for temperatures ranging from around 0°C (32°F) to 95°C (203°F) or even higher, depending on the specific product and manufacturer.
Pressure and Temperature Ratings: Confirm that the fitting's pressure and temperature ratings align with the requirements of your plumbing system. Both hot and cold water systems experience pressure fluctuations, so the fitting must be able to withstand them.
Code and Standards: Ensure that the fitting's temperature resistance complies with relevant plumbing codes, standards, and regulations in your region.
Application: Consider the specific application and potential temperature variations. For instance, in applications where hot water temperatures can approach or exceed 95°C (203°F), make sure the fitting is rated for those temperatures.
Installation and Maintenance: Proper installation and maintenance are crucial to ensuring the fitting's longevity and performance. 
Insulation: In some cases, using insulation around the pipes can help maintain desired water temperatures and reduce heat loss.
 Choosing a fitting that is specifically designed for hot and cold water applications will help ensure the longevity and reliability of your plumbing system.
