Higher corrosion resistance than standard galvanized products is effective in specific corrosive environments.
The "FIRG-Q" flat face coupling is suitable for the transfer of weakly corrosive environments and corrosive liquids (such as sugar water, water, glycol, etc.). This product is made of carbon steel and undergoes special nitriding and oxidation treatments on its surface. The internal valve components are made of stainless steel AISI 303, and seals can be selected according to the type of liquid and operating temperature. The flat face design eliminates leaks during connection and disconnection, preventing contamination from entering the system. The "FIRG-Q" series, featuring a flat face design and corrosion resistance, is primarily suitable for industrial machine applications. 【Features】 ○ Easy to clean, effectively reducing contamination intrusion into the system ○ No loss due to leakage of hydraulic oil during connection and disconnection, reducing environmental impact ○ Minimizes air entrapment during connection and disconnection, aiding optimal system operation ○ Patent-pending internal component design minimizes pressure loss → Prevents reduction in system efficiency ○ Higher corrosion resistance than standard zinc-plated products is effective in specific corrosive environments ○ Strong against peak pressure ○ Compact appearance ○ Safe and simple to use ● For more details, please contact us or download the catalog.
