Reddit mentions of Learn to Brew Keg Lube Lubricant, 1 oz

I have a similar set up with room for a carboy. When I started I had issues with leaks as well. Several inexpensive purchases have made all the difference:

1. Use Metal Screw Ties on each end of all hoses: https://www.cabletiesunlimited.com/48s-all-stainless-steel-hose-clamp.html?fee=1&fep=1575&gclid=CjwKCAjwyOreBRAYEiwAR2mSkgiOzu-NcMud2_7SY3QnpViiOOjpOdYbQlTiXqrc3ShRpnI079ETQRoCt1wQAvD_BwE
   
   
2. Use Keg lube: https://www.amazon.com/Learn-Brew-Keg-Lube-Lubricant/dp/B0114B4LBM/ref=sr_1_5?ie=UTF8&qid=1541099323&sr=8-5&keywords=keg+lube
   
   
3. Oftentimes the piece that connects the hose to the keg is actually 2 separate pieces. Make sure to use a wrench to tighten this as tightly as possible.
   
   
4. Replace the O-ring between the CO2 bottle and valve semi regularly.
   
   Hopefully those four things should help cut down on any leaks. You can do all of them for under $20. You can also buy a cheap dehumidifier on Amazon to help with condensation issues:

   Last, I found who fills the CO2 bottle can make a huge difference. The bottle actually needs to be chilled to get a full charge of CO2. My local fish store is significantly cheaper to fill, but they never give a good fill; I have to pay extra at the Homebrew store to have them do it right.
