Seals ( Silicone ) and Spacers Kit ( 60129-10 or new part number 60129-20 and 601029-30 ) for Fleck 2850 Valve.
What is the difference between the two seal sets ( 60129 and 60129-10,20,30 )?
* The cheaper one ( 60129 ) has brass spacers that don't hold up as well ( or as long ) as the plastic version.
Also the material used to make the Seals in this Kit are a better grade ( 559PE ).
Smart Dealers always use the more expensive version to avoid "call backs".
Are there any specialty tools that I would need in order to rebuild this valve head myself?
** There is an expensive stuffer tool ( Stuffer Assembly 2850 and 9500 - 16516 ), but since your valve is "large" ( 1 1/2" bore ), you should be able to "set" the parts with your fingers ( especially if you remove the piping connection at the rear of the valve body ).
Includes ( 5 ) Plastic Spacers - PN 16638

After additional testing, we found that the seal used in -20 kits is as good as the chemical resistant seal used in -30 kits, eliminating the need to keep both.
Starting May 21, 2018 there will only be one plastic spacer kit part number. The -20 kits will include the EPDM seals and the list price will be lowered to match the -30. At the same time the -30 will become obsolete in our system.
