rafju Posted March 12, 2020 Share Posted March 12, 2020 HI All Got a "coloured" question ;-) Does the U.S WWII airplane (any company) had their hose joints of a dedicated colour as they were used for oil, gasoline, hydraulic... Any info are welcome. TIA Raf Link to comment Share on other sites More sharing options...
Juggernut Posted March 12, 2020 Share Posted March 12, 2020 Yes. If you have a dash two from any WWII U.S. aircraft, there should be a section on finishing and probably includes color coding for fluid lines and fittings. Recollection of colors is: oxygen - green, fuel - red, oil - yellow, hydraulic - purple. There are others, I just don’t recall what they are. rafju and Trak-Tor 2 Link to comment Share on other sites More sharing options...

thierry laurent Posted March 12, 2020 Share Posted March 12, 2020 Technical manual. Link to comment Share on other sites More sharing options...
Juggernut Posted March 12, 2020 Share Posted March 12, 2020 Yes, apologies; the dash two is the Erection & Maintenance manual. FYI: The dash four is the Illustrated Parts Catalog, the dash five is the weight and balance manual.... Trak-Tor 1 Link to comment Share on other sites More sharing options...

Trak-Tor Posted March 17, 2020 Share Posted March 17, 2020 (edited) I was just checking out what's new at aircorps library and bumped into this: It says it was approved in January 1942, with last amendments in August 1949. There's also a second page with styles and sizes explained. I don't want to put it here in full resolution, there might be some copyright issues involved. But here are the colors that may be useful for WWII aircraft: Fuel system - Red Water injection system - Red/Grey/Red Lubrication system - Yellow Hydraulic system - Blue/Yellow Instrument Air Vacuum - Orange/Grey Coolant System - Blue Breathing oxygen - Green Air conditioning - Brown/Grey Fire protection - Brown De-icing system - Grey Well, I hope that helps.

Here's the specific page from the P-51 Mustang's dash two (Erection & Maintenance Manual) for fluid line color coding: Trak-Tor and rafju 1 1 Link to comment Share on other sites More sharing options...
