Contact Rings

Available Contact Rings

The contact rings shown here are fabricated from finger stock. These rings can be formed in any diameter containing an integral number of fingers, down to the minimum diameter to which that particular strip can be curled. This limit is spelled out in the tables of specifications under "Min. O.D."

Another important specification is indicated in the table as dimension "E", the "recommended mounting dimension." This figure provides for the proper amount of compression against the "plug" to assure a good contact.

Many variations of these rings are possible. Full information on custom forming is available on request.
