Hi will this be able to repair the union ring for Hayward T-Cell-3

Yes, it should work as a generic for the OEM union

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

A  Answered on 6/12/2020 by InyoPools Product Specialist Megan C.

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.

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

A  Answered on 1/7/2021 by InyoPools Product Specialist Hector F.

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.

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?

A  Answered on 9/1/2016 by InyoPools Product Specialist Lennox H.

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

I have a circupool si30 salt cell. Is this the correct split nut I would use to replace the existing broken one

A  Answered on 11/17/2015 by InyoPools Product Specialist Lennox H.

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