Here, you will learn easy steps to check, refill, and care for this fluid so the chair always works just right.
What Is A-dec 200 Dental Chair/Delivery System Hydraulic Fluid?
A-dec 200 dental chair/delivery system hydraulic fluid is a light, non-foaming oil made just for the A-dec 200 family of chairs and delivery units. It is labeled as part number 61.0197.00 and comes in a one-pint bottle.

- Why “light”? A light oil flows easily at room temperature, so parts respond quickly when the dentist presses a control.
Because this fluid meets A-dec’s exact standards, it keeps the chair’s pump, valves, and pistons happy and working for many years.
