Same Diameter

The Watt-Flex® cartridge heater is split sheath and required spacing in the header to accommodate its ability to expand when energized. The header is 1/8" larger in diameter than the heater and has an offset cut into it to allow for expansion. The larger diameter acts as an insertion stop so the heater is pushed into the bore as far as the header will allow.

But very occasionally there is a space restriction at the terminal end, such that the heater must be inserted in the bore up to the hose in a right angle configuration or completely into a bore with a straight header. In these cases we manufacture a "same diameter" header ... the heater is swaged down at the terminal end and the header is installed over the reduced diameter.

This allows insertion of the heater in the bore up to the hose or braid attachment, or completely in the bore in the case of a straight header. There is, of course, an increase in the price of this attachment, but it allows the use of a Watt-Flex heater in an application that, otherwise, would be prohibited. Welding of this header would be done on both sides of the heater, but expansion in the bore would still occur as long as the heater is 10"+.

Things that it took me over 50 years to learn:
by Dave Barry, Nationally Syndicated Columnist

1. If you had to identify, in one word, the reason why the human race has not achieved, and never will achieve, its full potential, that word would be "meetings."
2. There is a very fine line between "hobby" and "mental illness."
3. People who want to share their religious views with you almost never want you to share yours with them.
4. You should not confuse your career with your life.
5. Nobody cares if you can't dance well. Just get up and dance. (I wish I had!)
6. Never lick a steak knife.
7. The most destructive force in the universe is gossip.
