Does anyone has an experience of using John Guest speedfit

Is it possible at all use such a fitting for metal tubes?

thnx

those come with a 5/8 and 3/4 inch outlets right? how exactly will you mod those (for those of us that may want to go that route).

well im going to either hacksaw off about an inch of the tub and get some fittings that almost fit right in there then weld/solder them in

I thought those fitting are the best... Well... Which one would you suggest then and where to find them and how to identify them...

I already got those Hayden's radiators and I need some elbows.
Will use silicone tubes/hoses( whatever ) ID 3/8" OD 1/2".
Thank you vary much.

You want to use compression fittings correct?

I've been thinking about this for some time. Your best bet is to check out a local hardware store. They use these fittings for gas lines sometimes (at least where I work does).

Unfortunately they are harder to find in 1/2inch (actually most places sell by the Outter Diameter, so you'll need 5/8inch). Most often they are 3/8.

Also most are made for copper pipe and not tube

So if you want to use them with silicon tube, then you'll need an insert. I'm not sure what they're really called, but they look like bullet casings and slide inside the tube so that it doesn't collapse when you add the compression fitting. THey are also rare in 1/2in.

I'd use McMaster as a last resort. You probably need to look at these to get a feel for how they work (unless you already have some plumbing experience).

Most compression fittings are brass (through they come in other things too) and are meant to be threaded onto something. This will work fine on a pump like those made by Eheim and some waterblocks (DDen), but other things (rads) will need to have the fittings welded, soldered or epoxed on.
