Armstrong International B5586-1 Gasket

The Armstrong International B5586-1 is a precision-engineered replacement body gasket designed specifically for the A8 and B8 series float and thermostatic steam traps. Maintaining a proper seal in high-pressure steam systems is critical to preventing bypass and maintaining heat transfer efficiency. This gasket is fabricated from industrial-grade materials capable of withstanding the thermal cycling and corrosive environments typical of industrial steam heating applications. When performing routine maintenance or a full trap rebuild, replacing the secondary seals ensures the integrity of the cast iron body-to-cap connection. This component is essential for technicians addressing leaks in F&T steam traps that utilize 1-inch to 2-inch pipe sizes. By ensuring a tight tolerance fit, the B5586-1 helps maintain the differential pressure required for the internal float mechanism to discharge condensate efficiently without losing live steam, thereby optimizing the overall performance of the steam distribution network.

Key Benefits:

• Ensures a leak-proof seal for Armstrong A8 and B8 series traps, preventing energy loss.
• Engineered for high-temperature resilience in saturated steam services.
• Exact OEM fitment reduces downtime during critical steam system maintenance.
• Durable material composition resists degradation from boiler water treatment chemicals.
• Maintains system vacuum integrity in low-pressure return lines.

Common Questions:

Does this gasket fit both the 1-inch and 2-inch A8 series traps?
Yes, the B5586-1 is the standard body gasket for the specified A8 and B8 frame sizes; however, always verify the trap's manufacture date as casting dimensions can vary.

Can I reuse the old gasket if it looks intact?
No. Once the body bolts are loosened, the gasket's compression set is broken. Always use a new Armstrong B5586-1 gasket to prevent high-pressure steam leaks upon reassembly.

What is the maximum pressure rating for this component?
The gasket is rated to match the maximum operating pressure (MOP) of the A8 and B8 float and thermostatic traps, typically up to 175 psi depending on the specific trap configuration.
