Found air leak - how to fix?

My compressor started cycling every 30 minutes or so when previously it was once a day - maybe. 

The black arrow shaped valve in the first pic is what is leaking.  It is connected to what looks like a control box in the second pic.  There are 2 sets of theses labeled 1 & 2.  I'm guessing each one is for a slide.  Can someone confirm? 

If so, can I remove the leaking brass valve and connect the air line directly to the control box temporarily until I can get a new one?  It is probably not good that the compressor is cycling so often.

Yup, slide bladders.  Several of us have replaced them with ball valves from places like the compressor section at Lowes.

I'll do a quick search and post the threads in a minute

The Thomas TA-4101-DC is rated for continuous duty.  You should be OK with the compressor cycling but if it keeps you awake at night, you can pull the inline fuse and that should keep it from running (look for a fuse holder in the line to the compressor).

Thanks so much Michelle - looks like a trip to the hardware store.  Can I just disconnect the compressor (I found the inline fuse) then let the air out of the bladder and then replace the valve?

Steve says "yup".  That's how he did ours.

I believe when you disconnect / turn off the air compressor the air bladders around the slide will maintain their air pressure for some time.  Some folks have had pressure in the bladder for weeks.  We often turn our compressor when on flat and level ground while parked and the bladders do not lose pressure for a week or two at a time.

Thanks everyone.  Got to get to the store then to work.  That space seems awkward to work in.  Oh well things could be worse.

You might add a simple SPST switch to your shopping list, then put it in the same line as the fuse.  Easy to shut it off instead of pulling the fuse.
