Connection Specifications

Two proven methods of heating element terminations at Tutco insure a sturdy and electrically sound connection. The methods are compatible with ring, slotted and female terminals.

1. The resistance wire is mechanically staked and heli-arc welded to an appropriately sized slotted-head machine screw. It is then mounted with anti-rotational insulators to prevent movement during installations and operation.

2. The resistance wire is mechanically crimped to a 1/4" of 5/16" spade terminal which is then mounted in either a single or double ceramic insulator block. Pioneered by Tutco in the early 1980's, it has proven both reliable and cost effective for applications of 25 amps or less.

       Founded in 1938, Tutco has quickly grown into a global leader in the heating component industry. We supply electric resistance heating elements for a broad range of applications, including compressors, clothes dryers, duct heaters, heat pumps, window air conditioners, vending machines, and flexible heaters for medical & lab equipment. In 1994, Tutco was purchased by the Smiths Group, which has brought even greater resources to our products through the group's Specialty Engineering division.
