TRnorm Posted February 17, 2015 Report Share Posted February 17, 2015 Quick questions I hope. Should the heater water take-off from the head be a parallel thread, and would the fitment be OK in brass? Thanks for any advice. Regards Norman Quote Link to post Share on other sites
pfenlon Posted February 17, 2015 Report Share Posted February 17, 2015 Pretty sure its a tapered thread, with PTFE tape as well. but others will soon help out. Quote Link to post Share on other sites
Chilliman Posted February 17, 2015 Report Share Posted February 17, 2015 I agree with Pete and believe it's tapered but in answer to the question about using brass adaptors - no problem at all, in fact thats what I've done on both mine - basic off the shelf modern plumbing parts which make it a hell of a lot easier to get leak proof joints, can be fully fitted with the rearmost head stud/nut in place and then angled appropriately to engage with the heater flow valve (I use the new generic ones not the original type that didn't really work)....and I always use PTFE. I'm talking about TR4's so not sure if all this is relevant to you. Hope that helps Quote Link to post Share on other sites
TRnorm Posted February 17, 2015 Author Report Share Posted February 17, 2015 Just to confirm it is a TR4 and Thanks Guys - that's what I wanted to hear - Tapered & PTFE it is! I guess that to clear the head stud/nut I need to source a swivel fitting, or are there ones with enough height to clear the top of the adjacent stud/nut? (Quite a few on ebay but the dimensions are lacking.) Thanks again Norman Quote Link to post Share on other sites
Chilliman Posted February 17, 2015 Report Share Posted February 17, 2015 Here's what I'm referring to Norman, it's a two part affair, I'm not a plumber and don't know the correct names but I'm sure someone here could assist. Basically it's a double male union that goes into the head to give the extra height for clearance above the rear head nut and then a male/female 90 degree bend which, with appropriate use of PTFE or fibre washers gives you an angle to attach to your heater valve.....

That looks like a good solution. Just an observation... It has to be the correct size/shape to screw into the head without having to remove the rear RH head nut &/or stud. - Unless the head is removed of course. Orig was not a right angle and the TR5/6 was a straight thing. Early car has a tap with removable outlet tube.

TRnorm Posted February 19, 2015 Author Report Share Posted February 19, 2015 Perfect The photos make it very clear and as I'm also no plumber either I'll print them off and down to the merchants. Although I do rather like the tap idea - Hmm? Thanks again everyone. Norman Quote Link to post Share on other sites
RogerH Posted February 19, 2015 Report Share Posted February 19, 2015 Hi John, at last!!!! I have been scratching my head for ages about obtaining a right angle fitting for the valve take off. I used two of the original iron fittings to get the outlet horizontal. I used a washing machine service valve and adapted a cable to it - works a TReat but uses quite a few adaptors to get it to all fit together. Your fitting should make it what I wanted in the first place. Roger service valve with cable Quote Link to post Share on other sites
TRnorm Posted February 19, 2015 Author Report Share Posted February 19, 2015 (edited) And developing John's idea one more step............. ...........I found 3/8" BSPT M-M http://www.ebay.co.uk/itm/120726691312 and 3/8" FM hose taper elbow http://www.ebay.co.uk/itm/Brass-Female-Elbow-Hosetails-Connectors-Barbed-connecting-Hose-tails-Fuel-Air-/121557771138?pt=LH_DefaultDomain_3&var=&hash=item61e7e5b6cc From same ebay vendor and has the benefit of a proper hose tail.
