pressure pots revisited

I don't use the 3/8" Parker hose between the cup and gun. The fluid and air hoses are different there. They are different in materials, sizes and pressure ratings. The fluid hose is 1/4" ID with 3/8" NPS female swivel fittings. The air hose is 5/16" ID with 1/4" NPS female swivel fittings. All have the tapered seat to properly mate with the fittings on both the pot and the gun. I think the fluid hose has a special liner. I use the standard DeVilbiss set of hoses, part number KB-4006. It's about 6 ft long which is entirely adequate. I think it's easier just to get a set of hoses all set up for that specific purpose than trying to put something together with bulk hose. Plus the fittings are special. I purchased a replacement hose set at Robbins a couple years ago but have not used it yet. The set is not siamesed like an oxy/acet hose set is but it should be. I tape mine together intermittently to serve the same purpose.

If I were to make my own up out of bulk hose, I wouldn't even consider 3/8" for that service - air or fluid. For one thing it's not necessary, especially for the fluid hose. The other is that I would want keep the bulk down as much as possible - makes for easier maneuverability of the gun.

I don't think you can beat that Parker 831 hose for general purpose air service. Pricey but worth it.
