The production date of your hose is provided two ways for Eaton Aeroquip hydraulic hose. A date code is usually printed with the exact production run date. The right and left picture depict the ink jet printed production date in white ink. After the hoses have been in the field, this date can be worn off, so to make it a more permanent solution, the date code is encrypted into the layline of the hose (may be written in permanent ink such as the middle picture or an impression strip has been used to permanently imbed the date code as well as other important data pertaining to the hose)
How to decypher the date code...
Simple! Look for the Q!
Most every hose will have the date code permanently imbedded into the hose and it is xQyy where x is the Quarter of the year it is made and yy is the two digit year that the hose was made. For example 1Q11 is first quarter 2011 or 2Q97 is second quarter 1997 (or 2097 depending when you're viewing this)
Easy quarter reference:
1: First quarter, (January 1st to March 31st)
2: Second quarter, (April 1st to June 30th)
3: Third quarter, (July 1st to September 31st)
4: Forth quarter, (October 1st to December 31st)
When you change out your hose and the life span of your hose is up is dependent on the application. When there is any question as to the viability of your hose and you are/or not sure about any hose you are currently using, replace it immediately with a hose that can be identified.
