3/8 water pipe

[simmy_bull]

I still have a few old stone building on 3/8 black pipe and I think it's brilliant stuff if you have to rejig water round lambing pens calving boxes etc much more flexible pipe than blue 20mm anybody know if there's a metric equivalent 15mm ish? Googles not coming up with much apart from expensive stuff for houses? TIA

Are you sure 3/8 isn't 20mm just measured different?

 

[simmy_bull]

It's not far off

Somewhere between 17 and 18 MM just seams to bend round corners much better than the blue 20mm I'll have to keep my eye out at farm sales! Photo taken just now on kitchen table seen as I'm already in the shite club

If you use philmac fittings then they should join both types. With a straight 20mm joiner if that helps.

Why not use 15mm domestic plastic water pipe and push fit connectors.

Not too bad for fittings ta I tend to use the plasoon ones with an adaptor. Found a rare bit of pipe the other day coming into the house black 3/4 but needed a green adaptor not blue and red different wall thickness apparently class C instead of D maybe? I think lots of good has come of the metric system for things like this.

Not found any as cheap as 20mm though and I don't like spending anything if I can help it. I'm only a poor hill farmer the stocks lucky to have a roof over there head

You'll find the low density (thick 3/4) won't need an adapter tit, ruddy good push to make it fit tho!

20 mm blue is nearer to 1/2 inch than 3/8
3/8 pipe needs an adaptor for most fittings
I just use blue 20 mm now as its cheaper than using inserts and less hassle

Would that match up to 25mm? This here green adaptor I was on about looked as near as dam it the same size as the pipe it was supposed to be adapting if that makes sense! Must of only been a fraction different in size nothing as technical as calipers here though to have a check as I'm defiantly more in the bodge camp than farm enginee.

Yea, last time I came across a bit it had an adaptor but wasn't a good fit so I just tapered the edge, put some Vaseline on it and forced it in the 25 mm coupler. Seals well just into the o ring but I may have used a funny colour split ring.

It's suprising what you can do if you play about I joined a garden hose one lambing time with a 1/2" adaptor and 3/8" split ring to make up the wall thickness or something like that. Or finding a pipe with a digger after tea time tends to concentrate the mind to find something that fits!

If you need to make up wall thickness in an emergency insulation tape does work

Page 8, Item number 467NG12(red) is what you would probably require.
Certain polyfast inserts can be used with some of the plasson fittings depending on the age.
Hope this helps.

Any old static caravans round your way? Loads of pipes and fittings under one of them. Ideal for lambing boxes etc!! Plenty pipes with Tees and elbows already fitted

The ones under a pikies caravan work best

If you're in the shite club already you can boil the kettle and use the boiling water to soften pipes to get inserts into them - remember to bring the kettle back in (clean!) when you're finished though
