Heater valve

My car is the later model fitted with the valve operated from inside the cabin.
I bought a new one around 18 months ago, its leaking already from the sliding spindle.
Recently, coincidentally, I was told the new ones offered now are suspect cheap imports, as is the case regarding so many parts these days.
Can anyone advise a higher quality unit ?
Or should I revert to the old fashioned manually adjusted under the bonnet type?
Thanks Richard.

Same here, I reverted back to a tap on the head - of the heater valve variety

Even they come with their problems, again some are cheap rubbish that fail quickly.

Had to change mine due to not fully closing rather than spindle leak on the 1st. Now tried one of the off set ones from ESM. OK
so far but time will tell

Thanks for the replies, I will see if Tom Roy can get me a better quality item, I dont live far away and can collect, I think I will attempt a strip down of the old unit, if it is just a naff seal between the body and the sliding spindle I may be able to do something with it.
Ever the optimist.

I fitted a Mini one to my Midget, has been fine for about 5 years. I find A series common parts from Mini Spares to be better quality and more reliable.
