Check McMaster catalog and do a search for 'sintered filters'. There some listed as mufflers and some as vented plugs. Mostly inch sizes but some metric. I'm not sure about whether the plugs are inch or metric.

Google capilano teleflex and hydraulic steering. Sorry. I'm in the middle of nowhere with intermittent internet.
