Rubber grommets are all organized by their varying groove width. The groove width of your rubber robbin should match the width of the panel in which you are installing the grommet. Each groove width selection of elastomer grommets includes varying groove, inner, and out diameters to meet the specifications of different applications while providing the best fit of the elastomeric grommet to ensure maximum protection. The groove diameter should match the diameter of the drilled hole that the silicon robbin will be inserted into. The inner and outer dimensions of the silica gel grommets will help to provide additional sizing specifications so you can pick out most suitable rubber grummet for your needs.
1). Oval Grommets
Oval grommets are used as a conduit where an oval shaped hole has been applied for protection of an oval shaped item passing through a panel.
2). Multiple Hole Grommets
Multiple hole grommets are used as a conduit to protect two or more items that are to be passed through a panel.
3). Horseshoe Grommets
Horseshoe grommets can be utilized for unique applications when a traditional insulation grommet can not be installed.
4). Mounting Hole Grommets
Mounting hole grommets are used when a large grommet flange is unpractical because of space limitations.
5). Rubber Insulation Grommets
Rubber insulation grommets have been designed symmetrically injection with an ID, OD, overall thickness, groove diameter and groove thickness.These grommets are used when a wire, tube or other objects are passed through metal, plastic or any material that may damage the outside surface of the object.
6). Extended Neck Grommets
Extended neck grommets can be utilized for additional protection, rigidity, and stability for the item that is being passed through a housing. They are often used for electrical wire that exits the housing of a unit and as plug for appliance.
7). Vibration Mount Grommets
Vibration mount grommets are utilized for noise reduction and protection from the forces generated in compression. These parts are designed with flanges that are not equal. The thicker of the flanges is intended to be the vibration isolator. Typical uses include mounting a small fan or motor.
8). Special ID Grommets
Special ID grommets are used to protect an item passing through a panel where a standard round straight hole insulation grommet can’t be used.These grommets may feature holes that are square, diagonal, tapered or uniquely configured inside diameters.
9). Blind and Plug Grommets
These grommets are used to seal off an aperture in a panel. Blind and Plug grommets are often used when a hole has been stamped into a panel for possible later future use but hole needs to be sealed before production.
