Good morning All:
Last Thursday I had a catastrophe in the shop.
A hose split in the dielectric system for my sinker EDM and I pumped gallons of dielectric oil onto the floor in seconds.
It seeped down into the downstairs tenant's space and did some damage there.
I want to rebuild the system so it is safer...it uses polyethylene tubing and compression fittings and I've had them spring leaks unexpectedly before, but never like this.
I'd like to use the same style of hoses that hydraulic systems use...I only have 100 PSI to deal with but the idea of an NPT fitting on one end and a swivel NPT fitting on the other end with a reinforced hose and swaged on fittings gives me comfort.
Sadly, the dielectric oil will eat the Buna N rubber that most hydraulic hoses seem to be made of, but Viton is impervious.
The hoses need to be flexible to actually connect all the bits together...I have to go from the pump, through the filters, through the chiller and into the flushing system, and the path is tortuous.
Also I fear rigid pipes might crack from the pump vibration.
So far I haven't found a source for Viton Hydraulic hoses, do any of you know where I could go for something like that?
I'm motivated to pay whatever it takes, so if custom hoses are in my future I can live with that.
Cheers
