Sorry I didn't answer you sooner, I haven't been on here in a month or so. I use a local filter and plumbing shop here in Toronto for my fittings. Since you're probably not in the same locale as myself here's some URLs: http://www.freshwatersystems.com/c-2...-fittings.aspx http://www.freshwatersystems.com/c-2...-fittings.aspx http://www.bwiplumbing.com/index.php...iewCat&catId=9 http://www.johnguest.com/range_spec....IPM&rs=1&id=23 I hope that's helpful.
