Hi Si, The 2" Small Flange Split Nut (KO4052) can be used with the flanged tailpiece for the Circupool Si30 salt cells.

The union nut on my floater 2 is cracked. Rather tan replace an entire assembly of valve, (2)45's and the union (all glued) will this replace the nut waterway 415-5000 cap that fits up directly to the pump?

Hi Paul, This split nut flange can be used in place of p/n 415-5000.

Will this coupling attach to a Sta-Rite Dura-Glas II pump?

H Tony, unfortunately, this split nut is not compatible with the Sta-Rite DuraGlas/ Max E Glas series pool pump. This pump series does not have any split nuts that are listed as compatible with it.

Could this be used to replace a cracked union nut for a Pentair Intellichlor IC40 salt cell?

Actually the correct unions' for the Intellichlor will be part number 2824-050 that you can view by clicking here.

    I have a cracked union nut for the Pentair Intellichlor IC40 salt cell. There isn't enough pipe to cut off to install a new coupler and nut without installing new Jandy valves and reconfiguring all the pipes. Will this item work to replace the cracked nut? Thanks

      We do not recommend it, the majority of the Pentair threads are unique threads. The Intellichlor Replacement Unions - 520595 is the suggested part number for the proper installation of the Intellichlor salt cell.

can this split nut be used on a hayward pool pump with 2in threads
 Reply

A  Answered on 10/30/2024 by InyoPools Product Specialist Rich N.

Hi Jerre, the answer is "probably".  There are a lot of Hayward pumps and unions out there, but if yours is 2" and has buttress threads then this should work.  This guide can help you identify buttress threads versus regular V-threads.

Hi, I have a hawyard salt cell with a cracked nut . Will this split nut work?

Hi David, the 0121109020 Split Nut will be a perfect replacement for the cracked nut on your salt cell union.  You may want to get some new salt cell o-ring gaskets to be sure it seals up perfectly.
