3/4 tri clamp union

Postby Astro » Thu Mar 29, 2018 7:12 pm

After a bit of help with my pot and lieberg, its joined by thread
29595566_10156290940354028_5075717497422473230_n.jpg

And im not happy with the angle it tightens up at, so im wanting to remove the threaded ends and replace with 3/4 copper ferrule and use a clamp.

problem is i cant find 3/4 copper ferrules, anyone know where to obtain some. 5 star have what i want in SS but unsure if i can join it to copper? :angry-banghead:

You can join a stainless ferrule to copper, look in the “tips from the workbench “ section. Will possibly be safer than that brass union.

I'm the first to admit im no builder, this tri clamp union is advertised as 3/4. does that mean thats what size pipe will fit in it.
Is it the one i need?

Most tri-clamps seem to be advertised at the od of the pipe, as to fit to a regular female copper pipe socket of that size
The next 1/4 up usually is only a mm or two bigger, easily filled by solder, try to find A listing of the dimensions by size and you will figure it out, most of the smaller ss clamps have a 2mm wall thickness

I've got some of those and have used them, their bloody fantastic. I can check their size for you tomorrow if you like. I have a feeling that 5/8" copper pipe fits snug inside the 3/4" unions not 3/4". I think 3/4 would fit over the top, I think??

Well ya can't say I'm not dedicated to the forum, I just went for a walk to the shed in what feels like -105deg frosty weather to check for ya :laughing-rolling:

5/8" (15mm outside diameter) fits inside the 3/4 triclamp union. 3/4" (19mm outside diameter) will have to be expanded to fit over the union. So the unions are 15mm inside and 19mm outside.

Hope that helps :handgestures-thumbupleft:

Get the copper expanded. Ask a plumber to do it, it would only take 5 mins. He'd probably do it for a beer :handgestures-thumbupleft:

scratching my head having a rum session, if i remove these 2 OD 19mm pieces i can slide the ferrules in and hopefully solder without stuffing the other joins

I was more saying use a 3/4" joiner from the ferrule to your still but removing a bit of 3/4" pipe in your series of reducers will work as well.

Just an idea, replace the 90 degree bend for 2 x 45 degree bends with the triclamp ferrules between the 2 45s.
This will allow you to have any angle you want and gives you much more flexibility.
