Regulators Leaking

I was under the coach spraying everything checking for air leaks and found a couple of loose connections, a couple of air pressure regulators for the step that I tightened and replaced.
Then when I got to the two air tanks above the front axle I found these coming out of the tanks and both are weeping a little air.

They look to be Meritor Wabco brand ? 
Does anyone by chance know of a part number or vendor ?  I'm not even sure what they do.

Mark,

Those are your #60 pressure protection valves.  There are several threads that talk about these in depth as to there function.  They vary in price from $ to $$ depending on the maker and quality. Search around for the best deal. the diaphragm that are under the spring have failed due to age and started leaking. Years ago you could get a repair kit with new spring and diaphragm but those are long gone. Just replace with new.

Yes,
 yours are 1/4" pipe thread so make sure that is what you are getting by crossing the part number as the description in that add is kind of lacking good info, like opening/ closing pressure also.

Thank you for the follow up Mike, I really appreciate it.
It looks like this one may spec out closer to what I need, your thoughts ?

Mark,

I would prefer this one with known specs. even if it cost a few $ more.
