O-rings are rings that serve to ensure the tightness of fluids in industrial processes. They exist in different forms, although the most popular and used are the circular ones. The optimal closure is achieved with the deformation of the seal that is crushed by both parts of the seal.
In order for the seal to be perfectly adapted to a process, the dimensions and material of the gasket must be precisely calculated.
O-rings are versatile in their use, since they can be used in static processes (ensuring sealing at all times) or in processes in which there are opening and closing movements.
Although they are used for both processes, they require careful attention when selecting and installing them, since misuse of them can have negative consequences for the company.
One of the differential characteristics in a seal is the ability to withstand high temperatures. The fluids inside (whether they are liquids or gases) are subjected to high temperatures, exerting pressure that the seal has to withstand to certify the closure. For this, as we have explained previously, the correct choice of the O-ring is essential.
Below we list some of the most popular families:
At BULTZ we have V-Ring seals, available in all kinds of diameters.
Also for joints used in hydraulics and in different materials: PV, PTEF (for high speeds), NBR, FKM, HNBR, PVR, POM.
The seals are available in different materials and in all types of hardness, which allows adaptation to many industrial applications. They can be found in hardnesses of:
