Is the PSW-800 series pressure switch compatible with sea water?
The wetted parts in the PSW-800 Series switches include Buna-N and Brass. Buna-N has excellent compatibility with seawater. Brass however has a very poor rating. We cannot recommend using the PSW-800 in a seawater application.

Can these be used with 125 VDC? Are they compatible with diesel fuel?
The PSW-800 Series pressure switches cannot be used with 125 VDC. Maximum rating for DC Voltage use is 3A max @ 28VDC. The wetted parts would be compatible with diesel oil.

What is the thread size? I am looking to purchase the appropriate tap to thread this pressure switch into a schedule 40 pipe. Usually it’s pre threaded but this one was not.
The process connection thread on all ranges of the PSW-800 Series pressure switches is a 1/4-18 NPT male thread

Do the pressure and vacuum switches have an IP rating?
Although the PSW-800 are sealed very well they do not have an actual IP or NEMA environmental rating.

Are these switches compatible with DOT 3 brake fluid?
