[BusNit]

I have a couple of connections that leak at the fitting that screws onto the inlet of the water filter. Normally, I have been cutting these out and converting to Pex with a poly/pex converter fitting and then using a stainless steel braided sink hose for attachment. Where the water filter is located, it is a much tougher challenge. I would rather replace this bushing and move on with my life. I can't seem to find these. Does anyone have any ideas?
Thanks
