Hi all, 

 

I want to install a capillary gauge to my Mini and have this (see attached photo) fitting from mini spares which sits on the heater valve position. I think this is 5/8 UNF so its the same as the engine block original sender's positions. 

Anyone know a reliable capillary gauge with 5/8 UNF threads that attached to this fitting?

 

p.s. The reason I am not installing it in the original block position is because i have A/C and the alternator is very close to the sender unit (which will be too close to the capillary tube and may damage it !) 

 

Many thanks

I believe that most capillary temperature gauges have a female fitting.  When used in the cylinder head of the car an adapter is used that is male on both ends.  The male adapter would fit into fitting in the picture.

Hi Ace01,
Found this Durite gauge which has a male fitting. I believe this would fit perfectly onto the red fitting above ?

Always make sure the 'bulb'(40mm on the one in pic), on end of capillary is not too long. Although the nut is 5/8 unf and will screw straight in, it can crush the end as you tighten it up. We usually fit a male/female adapter.

The Smiths, TIM and Racetech ones will all fit with the 5/8” UNF thread.

As Oz advises - check the depth that is available and if not sufficient use a TE5 adapter..
