Brass Compression Fitting Connector

The effects of temperature and pressure on PEX brass compression fittings are multi-faceted and will be explained separately below:

Effect of temperature 

Material embrittlement: When the PEX brass compression fittings works in a high temperature environment for a long time, especially when the temperature exceeds its normal operating temperature, the impact toughness of the material may decrease and embrittlement may occur. This may increase the risk of brittle fracture of the joint at or near the weld.IFAN factory 30+ years manufacture experience support color /size customization support free sample.Welcome to consult for catalog and free samples.This is our Facebook Website:www.facebook.com. 

Decreased pressure resistance: Rising temperature will make PEX hoses softer. This change will weaken the hose's pressure resistance and also reduce the joint's ability to hold the hose, thus affecting the working pressure. For example, test the set working pressure of the hose at room temperature of 20°C. If the temperature exceeds 20°C, the working pressure of the hose will decrease.

Accelerated aging: In high-temperature water, especially in high-temperature and high-pressure water environments containing impurities such as oxygen and salts, the aging of PEX brass compression fittings will accelerate. These impurities will increase the corrosion of the joint and cause the joint performance to decrease.

Effect of pressure  

Stability: Pressure is one of the important factors affecting the stability of hydraulic ferrule joints. In the hydraulic servo system, although the linear friction is small, changes in pressure may still affect the stability of the ferrule joint.

Sealing performance: Changes in pressure may affect the sealing performance of PEX brass compression fittings. Excessive pressure may lead to loose joint sealing, leakage and other problems.

To sum up, the impact of temperature and pressure on PEX brass compression fittings is mainly reflected in material properties, pressure resistance, aging speed and stability. In order to ensure the normal operation of the PEX brass compression fittings, the temperature and pressure in its working environment need to be strictly controlled to avoid exceeding its normal working range. At the same time, when selecting and using PEX brass compression fittings, factors such as its material, structure, and manufacturing process also need to be considered to ensure that it can meet actual needs.
