Understanding Ratings
Pressure ratings define the allowable operating pressure of valves and piping components under specified conditions. Common standards use PN, PSI, Bar, and MPa to classify pressure performance across residential, commercial, and industrial piping systems.
Temperature & Environment
Pressure performance is influenced by temperature and operating conditions. While standard thermoplastic systems are typically rated at -20°C, JARO’s upgraded material formulations are engineered for applications down to -20°C, helping maintain reliability in cold-climate installations.
Standards Compliance
Pressure units and ratings are commonly referenced by DIN, ASTM, and ISO standards. Accurate pressure conversion helps engineers compare specifications and select compatible components for international projects.

Common Pressure Units Explained
Bar
Bar is a metric pressure unit widely used in industrial, water treatment, and piping systems. One Bar equals 100 kPa and approximately 14.5 PSI.
PSI
PSI (Pounds per Square Inch) is the standard pressure unit used in North America and is commonly referenced in ASTM-based specifications.
MPa
MPa (Megapascal) is an SI pressure unit commonly used in engineering specifications and material performance testing. One MPa equals 10 Bar.
KPa
kPa (Kilopascal) is typically used for lower-pressure measurements in water systems, filtration equipment, and environmental applications.
PN
PN (Nominal Pressure) classifies the pressure capability of valves and piping components. PN16 is one of the most common ratings used in water supply and industrial piping systems. JARO's upgraded thermoplastic valve and fitting systems are engineered for reliable operation in environments down to -20°C.
kg/cm²
kg/cm² is a traditional pressure unit still used in gauges and technical documents across some international markets.
Pressure Ratings in Real Applications
Pressure ratings should always be evaluated together with operating temperature, installation conditions, and media characteristics.
For most water supply, irrigation, and industrial piping applications, PN16 remains one of the most widely used pressure classes. Long-term performance depends not only on pressure rating, but also on material quality, impact resistance, and sealing reliability.

PN16 represents a nominal pressure rating of 16 Bar under standard reference conditions. This is approximately equal to 232 PSI, making PN16 one of the most common pressure classes used in water supply, irrigation, and industrial piping systems.
PSI (Pounds per Square Inch) is primarily used in North America, while Bar is widely used in Europe and international engineering standards. One Bar equals approximately 14.5 PSI.
1 MPa equals 10 Bar or approximately 145 PSI. MPa is commonly used in engineering specifications and technical documentation, while PSI is more common in ASTM-based standards and North American markets.
PN (Nominal Pressure) is a pressure classification system used for valves, pipes, and fittings. Common ratings include PN10, PN16, and PN25, helping engineers quickly identify the pressure capability of a piping component under standard conditions.
Yes. Operating temperature can significantly influence the allowable working pressure of thermoplastic piping systems. As temperature increases, pressure ratings may decrease. Always consult the manufacturer’s pressure-temperature data when selecting valves and fittings.
The most common pressure units are PSI, Bar, MPa, and PN ratings. The preferred unit often depends on regional standards and project specifications. ASTM-based systems typically use PSI, while DIN and ISO standards commonly reference Bar and PN ratings.
PN16 provides a practical balance between pressure performance, system safety, and installation requirements. It is one of the most widely specified pressure classes for valves, fittings, and thermoplastic piping systems used in water treatment, irrigation, plumbing, and industrial applications.
Performance in low-temperature environments depends on material formulation and product design. JARO’s upgraded thermoplastic valve and fitting systems are engineered for reliable operation in environments down to -20°C while maintaining dependable pressure performance.
