Rad hose joining?
RazMan - 23/12/05 at 05:03 PM

I know I've seen these somewhere but the brain has gone into 'tilt' mode so perhaps someone can help me.

I need half a dozen alloy hose joining pieces for my 32mm radiator hoses. Ideally I also need one with a 15mm take off for the heater. CBS do a bolt in jobbie but I don't really fancy drilling holes in a hose, and I'd rather get something which is made for the job.

Any pointers?

CBS will make aluminium tubes to your specification, including T pieces of different diameters. They will even roll the edges for you so that they grip your hoses better. Their prices arn't too bad either. I bet they'll make just what you want.

My motor factor "motorserve" does them , but thats in MK, i'm sure most motor factors will have them, took me a while to spot them, best thing to do is phone and ask.

And i'm pretty sure those two sizes are supplied.

Good luck

PS: "Bolt in jobbie" sounds a bit suspect

Rally Design's new catalogue list's them, came free with Jan PPC. magazine.


RazMan - 23/12/05 at 08:56 PM

Actually since my first post I trawled around a bit and found some in various places but they all seem very expensive.
CBS will indeed make them up for me for about £8 a piece, Europa and Merlin are a bit more (but they are stainless). I can't find any mention of them on Rally Design but I bet they are the most expensive.

Maybe its just me being Scrooge-like (well, it is the season isn't it) but I just feel that bits of short alloy tube should be cheaper


*edit* I take it all back! Rally Desighn do them for £4.58

Sorted

32mm hose joiners from Rally Design £4.58 each +VAT , Sorry I was wrong about tee piece


iank - 23/12/05 at 10:26 PM

Merlin Motorsport sell these:

Not cheap unfortunately.

Just buy a length of 32mm alloy pipe from your local metal dealer, and cut your own, much, much cheaper, keeps more beer tokens in your pocket.

Ah but they will more than likely leak. The proper jobbies have ribs that seal better.

Have you had a look at what can be made from plumbing copper capillary fittings ?

Mick


RazMan - 24/12/05 at 09:12 AM

Unfortunately the plumbing suppliers only keep their standard sizes - 15mm & 25mm I think. These will do nicely for the heater though.


Fred W B - 24/12/05 at 09:18 AM

A tip that I saw on here - If using plain ally tube put 3 or 4 pop rivets through the ally tube where the bead would be. Should work just as well?

Cheers

Mix - 24/12/05 at 09:27 AM

Standard sizes I have at the moment are 15mm, 22mm and 28mm ID or 17mm 25mm and 30.5mm OD#

Mick


RazMan - 24/12/05 at 09:30 AM

That's a top tip Fred - I might have to try that on my two main pipes already installed. I got the length slightly wrong and had to trim the beaded ends off and I was worried about leaks.

Close, but no cigar I'm afraid Mick - I've ordered 6 x 32mm from Rally Design

The only thing I need now is a 32mm to 15mm tee piece.

Plain aluminium alloy or steel pipe is fine even ABS plastic works. No fancy ends needed just use decent quality hose clips.

--- dosen't leak at the joints
--- won't blow off


RazMan - 24/12/05 at 11:05 AM

I tend to go on the side of caution now days. I was having a hell of a time with my turbo hoses popping off the intercooler at 12psi until I got the hose mountings beaded. After that - no problems even at 20psi.
I know that water systems don't run at those sort of pressures but I just like to use belt & braces I guess

I would just buy 3 metres of 1.25" stainless steel hygienic tube, £20 ish for the whole piece.


Danozeman - 24/12/05 at 11:53 AM

As trident says. No beads needed. Just make sure both surfaces are clean and dry before u fit the hoses.
As for the t piece could u not get a standard one and get a 15 pipe welded on?

I probably could but I am pretty sure I've seen them for sale on one of the usual suppliers' websites. No sense in re-inventing the wheel is there

I'm off to my local automotive store who stocks Gates hoses. I might find something ready made.


cornishrob - 26/12/05 at 10:42 AM

i was going to say that, why not buy a length of pipe? half the plumbing in one of my fiestas ended up as copper pipe.

As I said earlier in the thread, plain pipe ends often leak or pop off under pressure so I want to have beaded ends to ensure that they are reliable.

I looked thtough the Gates catalogue at my local store - hundreds of hoses in all sorts of configurations. I've ordered a couple of useful looking ones to see if I can make them fit.


geoff shep - 26/12/05 at 12:09 PM

CBS do them but as you say, not cheap.

I got a reducing 'T' piece from an auto jumble stall at a show which I put into the bottom hose. It has longish narrow tube coming off the T which is stoppered with an alloy bung - which I can use to empty the cooling system where I want and not have the coolant spray all over the place.


Chris_G - 26/12/05 at 01:07 PM

Here's a top tip I picked up a while ago and used on my cooling system. Takes a little bit of time and patience but works a treat and is in the 'Locost' vain......

Excellent tip - thanks


cornishrob - 27/12/05 at 10:55 AM

thats a cunning plan, I WILL be remembering that!


DarrenW - 27/12/05 at 02:47 PM

Mac#1 made mine up, cheap too. They will do any standard diameters and lengths. I also got smco hose from them - looks well smart.

I can see that this would be a good solution to stop them popping off. However, it won't help the seal as you now have an uneven ridge..


stevebubs - 27/12/05 at 03:40 PM

PS Got all mine from allyfab

All this beading the ends and bodging about with JB weld loks a right clowns game!!!!!

why the hell bother when a properly prepped stainless pipe inserted into a decent silicone rubber hose will NOT blow off.

I have had this setup to pressures that split an expansion tank, with a solid sealed rad cap, but the pipes nover blew off.

They only blow off when fitted to shitty corroded fittings or dirty fittings.

If you are still paranoid, then again, when using stainless pipe, simply put a run of weld around it as a bead, simple as that.

Strange.....I have run over 25psi boost on a cosworth turbo setup with unbeaded fittings and never had one come off..........and yes, water systems will be at that sort of pressure at the max end. I run a 14psi cap on my grasser and have blown that when it got really hot, and some competition cars run solid caps!

£20 a pop which, considering it is made to my exact requirements, is pretty good IMO
