Air Con Low Pressure Valve - Part Number ??????
« on: 30 August 2014, 12:59:49 »

Hi,

Just been to Nigel Langs and A/C now ICE COLD :y (Just ready for the winter  :D)

We replaced the High Pressure valve (courtesy of the much valued guide on here  :y ) as this I believed was why the pressure was lost since vac out and re-gas a few months ago (I even saw bubbles when cap undone)  NO leaks elsewhere when coupled to the A/C test kit.

It was noticed however that the Low Pressure valve (one by the bulkhead at back of engine bay on the top) did have a "small" bubble when all regas pipes removed. 

I am hoping that the valve cap maybe enough just to stop any small release (may have a chance as its on the Low Pressure side ?)

However, as a preemptive strike does anybody know the Part number for the Low Pressure valve ????

I believe it is a difference part to the HP Valve with the LP (Low Pressure) one more of a "Car Valve" arrangement with what appears the only bit to change the valve core in the middle ???? (like on car Schrader valve).

Thanks in advance.
Andy.

P.S
Just done my first Omega glove box handle replacement - what a faff !!! :o (now enjoying working glovebox  :D)

No idea of the part number, but it seems that it's the only one that the parts counter staff can usually find. Yes, it's just like a tyre/schrader valve.  :y

Is there no part number for the Low Pressure valve then ?  :-\ It looks as if I'm in need of one I can see bubbles once the dust cap has been removed.. Ideally need a part number by Monday.

is the seal in a normal tyre schrader valve compatible with R134a & the oil? Just asking because the seal supplied with the other is a green Viton seal  :-\ :-\

Confused now  :-\

According to http://www2.dupont.com/Refrigerants/en_US/assets/downloads/h45945_hfc134a_push.pdf Viton does not look the best replacement seal from table 6 when lists "Severely Unnaceptable change" when using HFC 134a !!

Fingers crossed !

Maybe it's not Viton then ..... just assumed it was. It's definitely green though  ;)
