Problems with Boiler Manway Gaskets

Problem

Boiler manway doors may not be centered due to wear on the hinges or difficulty in assembly, so there may be an excessive gap in one quadrant which allows the gasket to extrude, possibly springing apart and resulting in leakage.

Solution

The exclusive Flexitallic Style MCS Spiral Wound Gasket has an inner ring that prevents the gasket from extruding through the gap. Additionally, the inner ring:

• helps center the gasket
• acts as a compression stop
• prevents buckling of the gasket
• serves as a blowout device
• prevents the gasket from riding up on a chamfer or radius
