Robart Manufacturing 6' Pressure Tubing Orange ROB185 Wheels Gear Retracts & Accys

I am thrilled with this. In setting up pnuematic retracts, everyone suggests RED for extension and PURPLE for retract. In all my searches, I found no one who suggested any color - other than red - for airline fromair pressure intake to air pressure gauge. Well, THAT is exactly why I bought the oraange (wish I had bought more than one). I used orange from pressure intake thru various connections ending adjustable air pressure gauge (red). from there to retract units, I used RED for extension and PURPLE for retract as all suggested. Doing this eliminated ALL guessing about what air line goes to what.
