Expert Insights: A Q&A on the T4111 Single-use Elastomer Bellows Cartridge Seal

April 10, 2019 | 1 minute read


On the heels of our latest product launch—the T4111 Single-use Elastomer Bellows Cartridge Seal—we sat down with one of our product experts to learn more about the seal and all of its benefits.

In this Q&A, we share insights about how the T4111 came to be, how it differs from traditional packing methods, the types of fluids it’s best suited for and why it’s called a “single-use” seal.

In addition to being a great alternative to packing, the T4111 also boasts economic and environmental benefits. While the term “single-use” implies that the T4111 itself is not planned for repair at the end of its approximate 36-month life (under certain typical conditions), what’s great is that 95% of the seal can be recovered. Almost all operators already have steel recycling processes in place in their plants. At John Crane, we are committed to using energy and natural resources efficiently. Compared to a pump with gland packing that requires more frequent replacement of the metal sleeve and consumes a significant amount of water and power, we’re proud to offer an economic alternative that produces less waste.
