Urethane (or polyurethane) seals are among the most versatile and durable materials used in fluid power sealing. Urethanes are cast into billets or molds to create the seals used in many of the hydraulic components you see every day, such as pump shaft seals, cylinder pistons and rod seals. The material benefits from countless possible […]

Contributed by Danny Nghieu, EIT, Colonial Seal Elastomers are widely used due to their relatively high strength, low abrasion rate, and resistance to water, oils, and other chemicals. The mechanical properties of elastomers, namely their tensile strength and hardness, can change over time when the product is sitting in storage. The storage environment will typically […]

Contributed by James Czegledi, Engineering manager, Peninsular Cylinders It can happen at anytime, most often without notice — your cylinder has failed. More often than not the failure can be attributed to a seal or seals used inside of the cylinder. Let’s take a look at the types of seals typically found inside a hydraulic […]

The seals used in plant engineering must have a very long service life. Once they are installed — to protect offshore wind turbine towers from salt corrosion, for example — customers (typically) require that they perform perfectly for more than 20 years.
