works heater pipe

37 comments

  1. bought a works heater pipe from jk. you know the one that goes round the front of the cylinder head.

    the copper pipe is 15mm dia and came with rubber pipe that goes onto the copper pipe and reduces down to 13mm for the heater tap.

    the hose coming from the heater matrix is 13mm and obviously is too small for the 15mm copper pipe.

    is this correct the copper pipe being 15mm when the rest of the system is 13mm?

    thanks

    its still avalible its the first thing i checked 🙂

  3. The copper pipe that is available now is 15mm not 1/2'.
    This pipe is sometimes still called 1/2' because that's what it always was and it's actually about 1/2' inside dia, but externally, it's 15mm.
    The pipe for that heater was, as used on Works cars, the old 1/2' dia copper pipe, which now has to be 15mm, because that's all that's available. JK knows that and wouldn't have supplied you 15mm if 1/2' was available.

  4. Robert, what size pipe did the works use? Did they source 1/2 inch external diameter pipe so that things match up?
    Both 1/2 inch and 15mm heating pipe would have the same problem connecting to a 13mm hose as they are near enough the same external diameter, imperial sizes measuring the internal diameter where metric measure the outer.
    I would've thought an engineering shop the size of Abingdon would have been able to source a 1/2 inch o/d pipe.

    The Works used what was avalable in the 1960's at the time – and that was a standard 1/2' outside dia copper pipe, the likes of which was used everywhere.

    Now we don't have 1/2' pipe. All that is available is 15mm outside dia pipe.

    This will work with the car, the rubber connection to the heater valve and the hose to the heater will fit over the copper pipe, so it's no big deal. It's just that it 'looks' bigger than it should to be correctr for Works car or Works replica.

  6. Oh come on – are we really bothered, 15mm – 12.7mm = 2.3mm! Put your anoraks away, it's summer now – I think. Reminds me of 1966 and the lighting fiasco. Surely – 'The Legend Lives On.'

  7. Although 1/2' copper pipe is no longer used in general home plumbing it is readily available in the air conditioning/refrigeration trades.

  8. This debate is a bit surreal. Abingdon surely didn't source any bare pipe? The pipe used by them was, just as the pipe used by most private owners was, from an in line BMC engine/car (with a bit cut off IIRC).

  9. AMS is correct. The pipe should actually be 1/2' dia, but that's not available these days. The only way to get 1/2' copper pipe, is to find some old stuff. I bought some from a scrap metal man, who had a load of old rads and pipes from a house refurb. So commercially available new stuff, these days, will be 15mm – much as JK supplied to you.

    i was more worried about getting it to fit properly on to a 13mm pipe thats all and checking i had the right parts

    Yes you are so right, and you will find it, on a 60ies front wheel drive 1100/1300 (Marina in DK) model, but I would asume its only found on a LHD model,
    as the RHD will have the heater hoses, going through the bulkhead, on the passenger side.

    I agree with XYU767H -Its ammusing to see how people find enough time to handbag about copper pipe diameters. I trust that if one wants to replicate the 1/2' pipe then one must also replicate the correct pipe angle at each end ( a tolerance of +/- 0.5 degrees maybe ?) and ensure the that centre line height from middle of the pipe the top of the block is accourate ( plus minus 0.005' maybe) – Now where is that wooden spoon 😎

  13. hey northern – didnt you use some of yer grans old fallopian tube from the 60's……i believe all the works cars use those as every C*** seems to have one…..:D

    As I half remembered, they were standard on a Morris Minor 1000 in UK (saw an F reg one today, although the pipe had been painted black and I'm sure it was bare copper in period).

  15. Heater tap 'U' shaped pipe

    Does anyone know were I can get the U shaped 1/2' rubber pipe that fits on the end of the heater tap ? Does it come from some other vehicle ?
    thanks

    I was sure this had been discussed previously but I'm damned if I can find it! I have a vague recollection that at the time there was a suggestion of using part of a Spitfire 1300 hose. Obvious person to ask is JK.

  17. Was the source of these parts ever resolved?

    Likely the Comps Dept used their usual sources for parts that existed – the MG production line! I've just sourced the copper pipe from an MGA/early MGB (later MGB had a steel pipe with a kink in it). This pipe is 1/2inch outside diameter:

    Not cheap but is 90% there, just needs the long end to be bent to fit around the rocker box.

    The 180 deg rubber pipe I got from the same place is a Midget 1500 heater pipe, CHA359. Needs cutting down but fits the pipe perfectly.

    Personally would I get hold of a 1100/1300 spareparts catalouge.

    My answer would be yes, as I found the pipe on a LHD Austin 1300 .
    It runs on the back of the valve cover, and has the correct brackets, as per works spec, soldered on 😎

    I was thinking more in terms of Peckham Water. More honest that stuff! Luvvly Jubbly.

    Same water as Abingdon? Just passed through a few more people on its way down the Thames.

    Never mind st/work's water do you have any can's of Lucas loom smoke ?……if you have, do you know if it will work properly on a 1990 mainstream's rover loom ?

    I had a 1994 SPI in the workshop yesterday.
    It had NO problem what so ever, in creating its own wiring harness smoke;)
    Not sure if it can/will qualify, as genuine Lucas ? but it was smoke:p

    That makes me smile everytime I see it 😀

    wonder if Joseph would have smiled too 😉

    make an offer…”

    It looks part used !! and im sure the rover smoke was a lot denser than that 😀
