These rubber grommets can have different uses and can therefore be made in different shapes. On the market, you can usually find 38mm rubber grommets that are completely closed, semi-closed, or fully open. Generally, rubber grommets serve to secure openings on certain panels. Since they are made of high-quality rubber of exceptional durability, with this rubber grommet you can be sure that you have done the right thing. If you need to close the cavity completely with a secure and stable closure, then your choice will be a blind 38mm rubber grommet. If these are indeed the dimensions of the opening in question, simply installing this type of grommet will ensure that no liquid, objects, or dust will be able to pass through it.

If we are still talking about a cavity of the same diameter, so let’s remind you it’s 38mm, and you only need a couple of small cables to pass through the cavity, the best choice would be a semi-blind rubber grommet. It is cross-cut in the middle and at first glance, it would be said that it is completely closed. However, the flexible rubber can be moved and thus allow certain wire cables to pass through it or whatever is already needed. This high-quality rubber not only prevents the passage of cables and wires but also fixes them and protects them from high friction. The loose space, around the wires, will be absolutely safe and prevent the ingress of moisture or dust.

Fully open 38mm rubber grommets are usually used to protect cables or wires from the sharp edges of panels with only an extension. If you have measured the surface of the cavity well and chosen the right rubber grommet, you can be sure that you have a product that will benefit you for a long time, resistant to tearing and wear, external conditions, water, oil, or certain acids.
