When many people buy silicone seals, business people always ask how much inner diameter, outer diameter and wire diameter are needed. Some people can distinguish between outer diameter and transparent inner diameter, but what does this diameter mean? Then use the most intuitive images to tell you the difference between the inside diameter, outside diameter and the diameter of the silicone seal.

The cable diameter is only suitable for O-rings. Both rubber O-rings and silicone O-rings can be seen in the cross section of the figure. It is round, so the diameters of the cables are exactly the same. In addition, we will introduce a tablet. As shown in the figure below, the upper and lower sides of the seal ring are flat and the cross section is rectangular. Therefore, the outer diameter of the seal ring minus the inner diameter is not called the line diameter, but is called the one-sided width.

What must be considered here is the calculation method of one-sided width: one-sided width W = (outer diameter D-inner diameter d) / 2

As shown above, do you fully understand the buyer's inner diameter, outer diameter and wire diameter? If you have other questions about silicone rubber, you can consult B Best Rubber & Plastics, one of the most capable silicone rubber technicians can answer various related questions.
