Birmingham Seals - Hydraulic seals

What are Hydraulic Seals?

Hydraulic Seals are made from soft non metallic rings, and are usually used for the

separation of fluid leakage in motion appliances or machinery. Similar to R-rings

Hydraulic seals are very durable if they are used in the correct application settings,

however if they are used in the wrong way they can cause major problems. They are

very important components in machinery because of this. Another huge problem

could occur from choosing the wrong seal. At Birmingham Seals we offer and supply

a vast range of hydraulic seals which are available in a variety of different materials,

styles and sizes.

Material and styles

Hydraulic Seals are made from a collection of materials including polyurethane,

plastics, rubber, fabric reinforced elastomers and PTFE compounds. Hydraulic seals

prevent the leakage of fluid within the cylinder to the outside, where as a piston seal

prevents fluid leakage from flowing over the cylinder head. There are also two

pressure compartments which are on the rod and piston area of the cylinder. Before

the seal is in the machine you have to consider the different types of temperatures and

high pressures which will be applied, this is so that you can select the right type of

material for a hydraulic seal. In order for you to determine what material and type of

seal component you will need, you need to look at these various temperatures and

pressures. A piston seal is a type of hydraulic seal which comes in a selection of styles

like the PS1400 and the PS1800. The Piston PS1400 ring is made from PTFE and

rubber, in comparison the PS1800 is a double-acting piston.

Hydraulic seal common causes of failures.

The wrong installation of the seals is one of the common causes of failure. Installing

the wrong type of seal or installing the seal in the incorrect way can cause huge

problems for the machine. Another common failure is heat erosion. Heat erosion

failure is when the wrong type of seal is used because they have different resistant

temperatures, it is very easy to choose the wrong type of seal, but it can be very

dangerous for your machine. The hydraulic seal can break or crack from heat erosion.

Purchasing heat resistant hydraulic seals is one way to prevent heat erosion, ensuring

that the seal can still function in the correct way without being damaged by any

temperatures. Chemical erosion is another common failure. Chemical erosion can

usually be prevented if you choose the right material of the seal. This is because there

are numerous types of hydraulic seals and each of these are more resistant to different

types of chemicals, wear and tear.

Birmingham seals have a wide knowledge and experience with helping you select the

right seal for your machine, because vision is to provide their customers with high

quality seals and other related components by the most satisfactory methods.

Birmingham Seals are also able to determine which type, brand and style would be

best suitable for your machine.
