I posted this over at the NB Forum, but thought I’d try here, too. I’m working on getting my brew cart fitted-out. It will have two burners like this http://www.agrisupply.com/product.asp?pn=40282&sid=&eid= What I need help with is the connection between the burners and 1/4" needle valves like these http://www.bayouclassicdepot.com/nv108p_propane_burner_part.htm. I’d prefer to use something flexible like pneumatic hose. So, I think it will be something like a MFL x barb fitting at the burner end and 1/4" FPT x barb at the valve end.
The propane pressure will already be knocked-down by the regulator at the tank before it goes to the needle valves. So, is it okay to use 3/8" pneumatic hose secured to the barbs with hose clamps or oetiker clamps? Do I need to use something else? What have others used?
Is the metal flex hose you used similar to the 1/2" or 5/8" kind that is used for a gas appliance? If so, what kind of valve did you use to trim your burner? My turkey fryer burner has similar hose to what I found, and I’ve not had any problem with heat. As well, the orifice where the hose connects will be outside of a wind shield I’m building into the design - so I think it’ll be okay - but I’m still open to other ideas.
