4" ISO-RING SST SST IRD PRPY GLY LESS GAUGE TFE

This 4-inch stainless steel ISO-ring with integrated relief device (IRD) delivers reliable overpressure protection for industrial fluid transfer systems. Featuring TFE (PTFE) cylinder seals and propylene glycol fill without gauge, this ISO-ring provides chemical resistance and freeze protection.

Key Features:

• Size: 4 inch ISO connection
• Body Material: Stainless steel (SST) for durability
• Flange Material: Stainless steel construction
• IRD: Integrated relief device for safety
• Fill Fluid: Propylene glycol for cold climate operation
• Configuration: No gauge included (gauge-ready)
• Cylinder Seal: TFE (PTFE) for superior chemical resistance

Benefits:

• Stainless steel provides excellent corrosion resistance
• IRD ensures automatic overpressure protection
• Propylene glycol fill prevents freezing in cold conditions
• TFE seals offer exceptional chemical compatibility
• Gauge-ready design allows custom gauge selection
• ISO standard ensures universal system compatibility

Ideal for chemical processing, petroleum terminals, and industrial applications requiring chemical-resistant pressure monitoring with overpressure protection in 4-inch ISO connections.
