Hydraulic Seals

Hydraulic seals are widely used in a variety of hydraulic applications. These seals are made to withstand high pressure and are also highly corrosion resistant. Hydraulic seals use a liquid oil-based compound that is enclosed by a containing material and a cylinder that holds the seal together. These seals can help to prevent leaks in just about any type of hydraulic system cases. Common industries that use hydraulic seal technology include aerospace, automotive, government, medical, oil, gas, sanitary, and other industries that use heavy equipment. Commonly used hydraulic seals include: u-cups, vee, flange packing, w, piston, rod seals and cup-shaped seals.

Hydraulic seals don’t cost much to produce and can also be bought at relatively low cost. However, if they fail to do their job they can lead to repair bills that can cost thousands of dollars. Hydraulic seals are generally placed in cylinders to make sure the seals perform a back-up function in case one of them fails.

There are various types of common connectors for hydraulic seals such as port, tube-end, and hose-end connectors that make sure the fluid remains in the seal. Most hydraulic seals are generic and can be re-used among many different applications and industries.

Hydraulic seals work at a low operating pressure. These seals are differentiated on the basis of their sealing orientation and specification. While choosing hydraulic seals, some important factors need to be kept in mind such as: the outer and the inner diameter of the seal, the housing bore diameter, the thickness, the radial cross section, the operating speed, the operating pressure, the temperature, and the vacuum rating. Hydraulic seals are made from a variety of materials ranging from nylon, ethylene acrylic and polyurethane to bronze, cast iron, felt and leather.

One of the negative aspects of using a hydraulic seal is the leaking of oil and other compounds from the seal. Everyday instances of faulty hydraulic seals can cause damage to motors and components and can also make for unsafe conditions for operators of the equipment. Try not to expose the seals to temperatures that are outside of normal operating conditions. In addition, make sure the materials surrounding the hydraulic portion aren’t subjected to cracking or inappropriate torque.
