Non standard customized special-shaped parts

Non standard customized special-shaped rubber seals with irregular cross-sections are a type of rubber (or cloth) sealing ring with cross-sections other than circular and rectangular, collectively referred to as irregular seals, such as Y-shaped, V-shaped, U-shaped, X-shaped, D-shaped, triangular, and T-shaped sealing rings.
Chinese name
Rubber seal with irregular cross-section
Foreign name
specialshaperubberseal
shape
Circular and rectangular cross-sections
feature
Low friction and strong resistance to torsion
Special shaped rubber seals, due to their different structures, each have their own characteristics and can be used for different purposes. Compared with the O-ring, the X-shaped sealing ring has four circular protrusions in cross-section and two contact surfaces with the shaft. It only requires a small compressive force to achieve sealing effect, and has low friction, strong anti torsion force, and is not easy to slide; The D-ring has good resistance to biting and self sealing properties; The T-shaped sealing ring can prevent sprains, and when paired with a retaining ring, it can resist high-pressure extrusion, etc.
