looking for a lock-open shrader valve fitting for my compressor
I am using the Camco metal blow-out plug to assist with clearing my lines off my air compressor. The camco blow-out plug uses a standard automotive shrader valve to allow/isolate pressure. The issue is I am doing this process solo and currently only have a manual tire chuck for my compressor, so I need to either:
(a) -- open up a tap inside the trailer and then externally apply pressure, "trusting" that physics does its job correctly multiple times in a row (yeah, I know - difficult to trust that stuff since when I fall down, it always hurts)
- or -
(b) -- apply a level of pressure to the system until it equalizes with the pump and then enter the trailer to operate the valve; giving me 5-8 seconds of pressure before it dies out.
Faucets are fine; my worry is the toilet and toilet wand which must have human intervention to operate and cannot be left on.
Since I am a relative air-compressor n00b, can someone suggest a fitting I may want to try to permit me a "constant on" shrader fitting that will let my compressor equalize to the Airstream-manual required 60 PSI without any intervention on my part, allowing me to stroll through the trailer opening up the valves in one continuous sequence without multiple entrance/exits to finish the job?
