Maximum temperature depends on the seal
Brass Press Fittings have a maximum temperature that depends on the O-ring. EPDM O-rings handle up to 250°F (121°C). HNBR O-rings handle up to 300°F (149°C). Example: a fitting with an EPDM seal.
EPDM temperature limit
Brass Press Fittings with EPDM seals handle up to 250°F. This is suitable for most hot water systems. Short-term exposure to higher temperatures is acceptable. Example: a hot water line at 180°F.
HNBR temperature limit
Brass Press Fittings with HNBR seals handle up to 300°F. HNBR is used for higher temperatures. It is also used for gas applications. Example: a fitting for a high-temperature system.
FKM temperature limit
Some Brass Press Fittings use FKM (Viton) seals. FKM handles up to 400°F (204°C). This is for extreme high-temperature applications. Example: a fitting for industrial processes.
Pressure derating at high temperature
Pressure ratings decrease at higher temperatures. A 600 psi fitting at 250°F may be rated lower. Always check the temperature-pressure chart. Brass Press Fittings require derating for heat.
Example: hot water system
A building has hot water at 180°F. Brass Press Fittings with EPDM seals handle this. The system is reliable. Example: a reliable hot water system.
Example: high-temperature heating
A heating system operates at 250°F. Brass Press Fittings with HNBR seals handle this. The system is efficient. Example: a reliable heating system.
Example: industrial process
An industrial process operates at 350°F. Brass Press Fittings with FKM seals handle this. The system is reliable. Example: a reliable industrial system.
Manufacturer specifications
Always check the manufacturer's temperature rating. Ratings vary by seal material. Brass Press Fittings should be used per guidelines.
Seal material selection
Choose the right seal for your application. EPDM for standard hot water. HNBR for higher temperatures. FKM for extreme temperatures. Brass Press Fittings with the right seal last longer.
Final temperature summary
Brass Press Fittings have a maximum temperature that depends on the seal. EPDM handles up to 250°F. HNBR handles up to 300°F. FKM handles up to 400°F. Pressure ratings decrease at higher temperatures. Brass Press Fittings are suitable for many high-temperature applications. Example: choose the right seal for your system.
