Unicel Model: 5ch-502, Pleatco Model: unknown, €37.50 (inc. VAT)

Important Information:

Old Pleatco brand threaded filter cartridges have a removable male pipe thread fitting which slip-fits into a 1.9" hole in the filter bottom. You may need to unscrew the male pipe fitting adaptor from your spa's filter housing if it did not come out with the old filter. The filters that we have manufactured are moulded in one piece, and therefore the threaded fitting comes out as part of the filter.
