D-RING

A D-ring is a type of sealing ring used in machinery to prevent leakage of fluids or contaminants. It has a "D" shaped cross-section, with one flat side and one curved side. The D-ring is commonly used in hydraulic and pneumatic systems, as well as in various automotive and industrial applications. The shape allows it to create a secure seal between two parts, often preventing the escape of oil, water, or air, while withstanding pressure and wear. D-rings are made from durable materials like rubber, elastomers, or metal for different sealing needs.
