Hi Folks,
A quick Google hasn't turned up any sources, so does anyone have a
source of fittings to connect 5mm plastic tubing to (say) 15mm copper
pipe?

Whilst working on a door canopy yesterday I took the opportunity to
snake some
5mm clear plastic tubing through the void and positioned one end where
a
hanging basket normally resides.
The plan is to timer-connect this via a washing machine solenoid valve
so that the
hanging basket gets watered in the summer.

So one end will dangle near the basket, but my issue is how to connect
the
other end securely to mains water pressure (throttled back by a valve
somewhat).

Anyone got a source for fittings?

Thanks in advance

Mungo

RS etc, you want compessed air fittings which will take you from 5mm to 1/2
bsp etc

I've used these in the workshop for compressed air use with pneumatic
clamps etc. They are cheap and work well, although 4mm and 6mm are a
lot more common than 5mm.

Mungo doesn't say what type of flexible tubing, but these fittings are
meant for fairly stiff nylon or PTFE tube. If it's soft PVC tube, I
am not sure that they would grip it properly.

Another point here is that if this is a hook up to mains water, it
would be a good idea to add a pressure regulator and a check valve.

Obliged for the reply Jeff. I took a look at the RS website but I got
bamboozled
by whats on offer.
I guess there isn't one fitting that will fulfil my needs - perhaps a
combination
of a couple of fittings?

Good points Andy - thanks.

The tubing I bought came from B&Q - I was focussing on other work at
the
canopy so I didn't give much thought to the diameter (hence the
problems
now).
Perhaps I can heat the end of the clear plastic tubing and force it
over the
outlet nozzle of the standard washing machine solenoid.

Good point about the check valve too: I will incorporate this in my
design.

as Andy has rightly pointed out, air pipe is 4mm, 6mm .... it sounds like
you have the sort of pipe used in aquarium applications, if b&q don't do the
fittings then try an aquatic shop

OK. If it's the stuff I think you mean (generally with things like
cords, chains etc) then I am pretty sure it's PVC.

I think that that might be pushing your luck a bit. Generally these
have about a 10mm tubing connector.

I'd try going through an adaptor first. As Jeff says - aquatic shop
should have these. You can get barbed connectors with different sizes
each side and then the tubing is held on with jubilee clips.

I got a stepped adaptor to 1/2" BSP from my local engineer's supplies. The
smallest end is fine for car EFI fuel hose so should be ok for 5mm plastic.

How about a "Gardena Micro Drip Irrigation - Master Unit 1000 1355 -20"
from
http://www.grovelands.com/acatalog/G..._watering.html

"Supplied with fittings to enable either ½" (13mm) Supply Tube or 3/16"
(4.6mm) Branch Tube to be fitted directly to the unit. A stainless steel
clip enables quick & easy connection or disconnection to the tube."

So the 4.6mm fitting should be ok if the tube is a but stretchy!

this will do the pressure reducing too :-)

Possible, but you may not want to site one of these in the house. IME,
products like this, intended for use in the garden, lack the
"continence" required for installation in the house.
