Hydrotherm BM-8024 Pressure Switch

Will this work just like my BM-8026 I can not find one wondering if this will work.

BM-8026 is not a good part numbers to us. Please reply us the model and serial numbers off the unit to try to ID the part.

What is the iwc value of this switch? I am looking for an .42 iwc and while visually this looks real close it might not be the right part.

Please see link below for the label attached on the switch.
