Spiral Balance Tube Part Number

We appreciate your questions. It appears your spring may be 3/8", however,the overall thickness will be 5/8" once the cover is attached to the balance. That being said, review our S600-29 spiral balance. Let us know if this looks like the one you have been searching for. Even though your current balance has a white colored tip, we actually suggest the red tip as being the better option. We'd also like to mention that a charging tool would be very helpful in the repair and installation. See our 75-006 for consideration. Lastly, if you would like more information about spiral balances, we placed some media guides on this page for you to look over.
