Clutch slave line sizes

[Classic Chim]

Hi guys.
Can anyone confirm the tube size and unions fitted on the clutch slave line please.
It’s a unf thread I think?
I’ve been trying to bleed my clutch and just can’t get a seal at the 4 way union end.
I was re using the original one but it’s got a slight kink in it that’s not acceptable so I’ve given up and want to get a new one made up.
Thanks

Bulkhead end union 7/16
Slave cyl union 12 mm
Using 1/4 in pipe.
Is this correct?

I found this from a thread I posted in a few years back if that helps: ( https://www.pistonheads.com/gassing/topic.asp?t=15... )

Got the hose made up, wallet now £55 lighter
Made it long enough to go down the back of the engine first and then back around avoiding most of the heat.
Fittings were 7/16 UNF at the slave end and M12 X 1.0 at the bulkhead manifold block.

I have just had a braided hose made up with same end fittings as advised above. Incidentally It cost me £55 as well.

Thats correct , I made up one fairly recently I used AN6 pipe and fittings IIRC

Thanks chaps.
I’ve got one being made By Proline braided lines in silver and delivered tomorrow by 1 pm hopefully.
Spoke to a chap called Josh who has done this for other owners. Very helpful and prompt.

I've been wanting to do this mod for a while, but this thread got me thinking about it again.
So I contacted Proline braided lines to ask the spec of what they have supplied before, and spoke to Josh who was more than helpful. Thanks Classic Chim for providing that information.

Also just to confirm as it has been mentioned either way around in the posts above. It is 7/16 at the baulk head and M12 at the slave cylinder end.

I decided to change the spec a bit and went for the following:


Couple of shot after install:

Proper job I used banjo fittings to get the 90 degree you have pre-formed and yes your thread specs are correct , yours is far tidier with less joins I was just being tight as I had AN6 hose already

Yes a really nice job.
After a bit of huffing and puffing I kept my Proline one and Josh sent me the male to male adaptor for the 7/16 bulkhead.
It looks ok and I’m pleased with it as they are cheap really.
I should have gone for your spec with the 90d bend on both ends but specified it 800 mm long so it curves back nicely so good to go.
I’ve been on other work so still to bleed it but can’t see any issues.
I’ll take a photo when done.
I’m still using the stock retention clip covered in rubber that bolts to bulk housing which works well.
Josh is very helpfull and I’d recommend Proline as a prompt and reliable company. The hose is quality.

Mark Davies and I ordered the 7/16th version of this from Proline and that’s correct for our early cars (mines an early 1992 Griffith) but as you discovered TVR changed to an M10 bulkhead fitting at a later date (when they fitted the bulkhead Union you have i think, on my car the clutch and brake pipes go through the bulkhead individually not via the bulkhead block you have).

So anyone ordering from proline (highly recommend at £25) then early cars need 7/16 at bulkhead, later cars with Union black on bulkhead need M10

Very neat Stefan

I have same bulkhead block/manifold (like pictured above) and its 7/16 UNF thread MK1 95

My Mk 2/3 2000 year car has 7/16 at the block connector too.
Are any of them metric at that end.

Yes some of them are M10 at the block, in fact that’s what I thought you said previously, Josh sent you the 7/16 Union so you could use the pipe he’d made up fir you?

Thanks for all the positive feedback. Always nice to give a bit back after all the years of using the collective knowledge of this forum.

I forgot to mention but I went with a 700mm hose length.

Interesting to hear about the 'stock retention clip covered in rubber that bolts to bulk housing', I don't have anything like that. But my car had been messed around with before I got it. So must have been left off / lost.
