25mm Rubber Cover Rubber Plug

A 25mm rubber cover offers a nominal size for closing or covering a matching component. Before choosing it, identify whether the stated diameter belongs to the outside profile, the cavity or the mating opening. These dimensions serve different purposes and cannot be substituted for one another.

Check the depth available inside the cover and the length of the end it will receive. A shallow cavity may prevent complete seating on a projecting component, while excessive depth can leave the desired contact undefined. The surrounding clearance also needs to accommodate the head or lip.

ETOL offers custom material, hardness and color options for this profile. Evaluate the cover on the actual mating part and inspect the entrance for distortion after fitting. Avoid forcing it over sharp edges or using a tool to stretch a size mismatch into place. When removing it for maintenance, keep the cavity clean before refitting. A worn cover should be replaced by its full fitted specification rather than by the 25 mm designation alone.
