Sealing components: pistons and rotating shafts

The reliable sealing of industrial machinery parts plays an essential role in a wide range of contexts; this is optimised by sealing components, which ensure a perfect seal between elements in which fluids or gases circulate, avoiding leaks or contamination from external agents. Choosing the sealing component that is suited to the particular application is essential, as is identifying the material that should be used for this essential connecting component. 

There are two main categories of sealing component; static seals, also known as gaskets, which are designed to be compressed, and dynamic seals, which are designed to withstand repeated movement. The areas of application for sealing components are many, and range from hydraulics to agriculture, from industrial equipment to the petrochemical, food and automotive sectors.


The task of GBL technicians is to assist each client in choosing the sealing component most suited to the application, and also to define the most suitable material, to ensure that the desired performance is achieved.



Sealing components in rubber or other materials?

The choice of material is one of the steps in designing and manufacturing a sealing component that will have the most decisive impact on the reliability of the equipment. Sealing components must be able to resist a range of external sources of stress, such as high temperatures, high pressures or particularly challenging chemicals characterising the liquids that they are required to contain.


The GBL catalogue contains a wide range of sealing components, which are available in a number of materials, such as:

  • elastomers such as ACM, EPDM, FKM, VMQ, FVMQ , CR, HNBR, NBR, NBR-PVC, SBR, NR, AU.
  • thermoplastic materials such as ABS, PA6, PA6.6, PA6.6 FG, PBT, PC, POM, TPE, TPU.
  • materials reinforced with fabric such as, for example, nylon, cotton or aramid fibres (ideal when a stable seal under high pressure is required).

GBL: leader in sealing components

Our goal is to respond to the needs of each client with personalised and efficient solutions that are safe and totally reliable. We are specialised in the production of high- and low-pressure hydraulic and fluid-power seals, which we design and manufacture thanks to a qualified workforce and a production machinery inventory that includes the most advanced equipment for moulding (either through injection or compression).


The quality of our products is furthermore guaranteed by certification that we have requested and obtained, such as IATF:16949 for the automotive sector, and ISO 9001:2015 which guarantees a structured and constantly updated Quality Management System.


Our constant investment in innovation and staff training allows us to play a role as an expert and competent market leader for the creation of all types of sealing component.
