When choosing sealing rings for grooved pipe fittings, what should you pay attention to when purchasing them? As a manufacturer of grooved pipe fittings, let me take you through them!
1. Working medium and working conditions
When selecting the O-ring seal material, the compatibility with the working medium must first be considered. The pressure, temperature, continuous working time, operating cycle and other working conditions of the seal must also be comprehensively considered. If used in rotating applications, the temperature rise caused by frictional heat needs to be considered. Different seal materials have different physical and chemical properties.
2. Sealing form
According to the load type, it can be divided into static seal and dynamic seal; according to the sealing purpose, it can be divided into hole seal, shaft seal and rotating shaft seal; according to its installation form, it can be divided into radial installation and axial installation. When installed radially, for shaft seals, the deviation between the inner diameter of the O-ring seal and the diameter d2 to be sealed should be as small as possible; for hole seals, the inner diameter should be equal to or slightly smaller than the diameter d1 of the groove.
