7/16" clutch hose?

thetim · Jun 25, 2016

I'm plumbing in a clutch from scratch. Most of my running gear is 300tdi, so I bought a 300tdi flexible hose, but it has a strange end - M12, with a flat end - won't seal against anything I can flare. I believe it screws into a special fitting.
As an alternative, I'd like to make up a short rigid pipe with a 7/16" UNF end on it, then source a flexible hose with 7/16" male fittings on both ends. I believe that these are common among Land Rovers (just about everything except the Discovery 300tdi...) - can anyone confirm? Part number RTC4425 might do it?

From memory and just building a track car, 7/16 is a very common size for master cylinder inputs. And it will probs be 3/8 not m12 on the other

Would imagine you need some sort of bulk head fitting to hold one end of the flexy,

Are you sure you have all correct parts?

You say running gear? What gearbox and slave do you have? Lt77 or r380
Found this but don't know what it's off and not to clear looks like it could b a Landrover

Definitely M12, unfortunately. Are there any flexible hoses that are 7/16 to 7/16 UNF? Am I right in thinking that that's what most Defenders run?
Gearbox is a Discovery R380 with matching clutch slave. Master cylinder is Isuzu. Agree regarding having some sort of bracketry to support the flexi - wouldn't seem sensible to rely on the rigid pipe to do it for me!

SWMBO's D1 is 7/16 UNF both ends, as is the scrap D1 we have too - presume you need some sort of adaptor - have a nosy at flea bay item # 281377150154 - I know its in Hong kong - its just the first one I found .....

Hi, thanks very much for checking. My daily driver has some odd one-piece hose which has a rigid section, a flexi section and then another rigid section all in one. Unfortunately the layout I've got means this won't fit on the thing I'm building, so I need a separate flex hose with 7/16 ends. I can get round the M12 fitting on the master cylinder's pipework with a rigid make-up pipe, M12 male to 7/16 female (there's already one there, it's just got M12 male parts on both ends) as long as I can then get a flexible hose for it!

I made my own flexy pipes for my track car just bought all the bits and put it together right lengths right bends looks much better
