　　The rod seal is the single most important seal on any piece of fluid power equipment. Our rod seals are consistent and durable, and are the subject of high praise from our customers.

　　Rod seals are designed to make sure that any pressurized fluid stays out of the system while the rod performs its job. Leaking rod seals can be quite dangerous—not only will they hamper the performance of your machine, but they will also cause some potentially harmful environmental issues. Therefore, it makes sense to apply a durable rod seal to your machinery so that you can minimize these risks.

　　There are two main varieties of rod seals: single-acting and double-acting. Single-acting rod seals seal dynamic pressure from one side, while double-acting devices seal dynamic pressure from both sides.
