Are there big issues trying to mix inch and metric size tubing and fittings?

Is 3mm close enough to 1/8 in and 4mm to 5/32 to allow for strong enough joints?

I like the Anton gas pressure regulator with low pressure cut off but my other fittings are inch based.

This subject has come up before, I am almost certain.
Do a search on the steam sections of the forum.
Also, try the Nautical College board and the Research and Design office boards as well.

4mm is 0.1575" and 5/32 is 0.15625", so close enough not to matter in most cases. 3mm is 0.118" and 1/8" is 0.125, so a bit more difference there. 3mm pipe will be very slack in 1/8 fittings and 1/8 pipe won't fit 3mm fittings.  If you have a lathe, or know someone who has, it's easy enough to get round the problem.

Hullo ...Landlocked......most Anton gas regulating components........& yes there are four available are soft sealed [o-ring sealing] but on 2.0 OD mm tubing

Do not be confused here with comments of "pipe" ......all of the tube components used here are OD tubing

The word pipe   relates to nominal bore

Should you decide to go the Anton way......it is relatively simple to soft solder capilliary telescopic tubing between your imperial tube sizes back to metric & back again..... ....Derek

Hi I have connected anton metric regulators to inch piping, and Metric Oiler to inch piping. Everything works well

Don't mix Metric with Imperial size tubes/fittings unless using a correctly sized adapter which invariably means access to a lathe. This only applies to the UK, let everyone else please themselves.
