Colors
Hydraulic pipes and plumbing are identified by a color coded tag affixed to the tube itself. The tags are half blue and half yellow or half green and half yellow.
Tag Type
The tags used for identification are manufactured with different materials depending on operating environment. General purpose tags are 1-inch tape or stickers circling the tube, metal tags may be used in hot or oily areas and special painted-on tags are used in areas where tag loss is likely.
Flexible Piping
In flexible tubing where standard 1-inch tags are not practical, stamped or printed plastic may be used. They are identified by the plain-language hydraulic fluid type occupying the hose or the specification code used in its manufacture.
