Gasket Manual Chapter 5 – Diagnosing Gasket Failures
Resource Description: Diagnosing Gasket Failures (Chapter 5 of the Gasket Manual). The gasket is but one of many reasons a bolted flange joint connection can leak. Even when all the complex inter-related components of a bolted joint flange connection work in perfect harmony, the single most important factor leading to success or failure of that bolted flange connection, will be giving attention to the proper installation and assembly procedures by the person installing the gasket. If done properly, the assembly will remain leak-free for the target life expectancy.

Resource Description: How to select a gasket (Chapter 3 of the Gasket Manual). Gasket selection can be complex or it can be as simple as selecting the right color from a shelf in the stockroom. However, selecting the right gasket for a leak-free seal requires much more thought and consideration. Though the best practice for gasket selection occurs during the system and piping design phase. The majority of the context that follows is focused on existing bolted flange connections.
