Dimensions:

• Inner Diameter (d): 7.5 mm
• Outer Diameter (D): 4.5 mm
• Thickness/Width (b): 3 mm
• Note: It's unusual for the inner diameter to be larger than the outer diameter. It's highly probable that the dimensions are listed in a different order or there's a typographical error. The standard convention for seal dimensions is inner diameter x outer diameter x thickness. Therefore, it's more likely that the dimensions are 4.5 x 7.5 x 3 mm.
