Old PN 157A140, New PN 1040279
Used in place of By Pass on Autotrol 155 and 255 models.Installation TIPS:MATING new parts to older parts can be a challenge with Autotrol valves.
The only advice is that the o-ring must be placed on the "male" portion first.
And the bolting needs to be put on "snug" by hand,
and then ALTERNATE tightening of the 4 bolts / nuts with a tool.
Work around the 4 points about 3 times, and they must be as tight as you can get them.
And even then, I've had struggles slow leak issues when attempting to mate the old parts to the new parts.
Be sure you do not "nick" or damage the 3 o-rings in any way.
