I assume you're talking about the Presta-to-Schrader valve adapter. You can get it in any of the many bicycle shops located around Phadke Houd Chowk in Pune. It should cost a mere 10/20 bucks. I got one for myself and it works just fine.

Is there one where I can get air filled into my tyres from the digital machines at tyre shops and at petrol pumps?
P.S. I have the normal Indian cycle type valves. Not those ultra long ones of imported bikes.

By normal Indian cycle type valves, do you mean the ones where you rotate a ring to let the air off? If so, I'm not sure if a Schrader adapter is available for that. Will have to check.
My bicycle (Montra) tubes have Presta valves (may be the ones you're referring to as ultra long ones). The adapter makes it fit for the motorcycle-tube-style pumps (which cater to Schrader valves).
I've got an al-cheapo cycle pump with two holes; one for Schrader and the other for classic valve (where you rotate a ring to let the air off). I use this adapter on the Montra along with the Schrader hole.

This type .....
From the photo, it looks like the rotate-a-ring-to-let-the-air-off type valve. Recent Google search revealed that it is called Dunlop valve or Woods valve. I haven't checked personally but am sure you'll get a Dunlop-to-Schrader adapter in Phadke Houd Chowk shops.
Yup, that's the name.
So Schrader is the car/bike air pump filling type valve right?
Asking for two reasons. Right now I have the old type pump at home which I use on all our cycles. And check pressure with hand. Because the tyre sidewall just has "inflate hard" written.
But there are tyres which have the exact pressure written (in psi and bar) so if I shift to them would like to know exactly how much I'm filling and not to over-inflate. The latter is always a fear when filling by "feel" that you will burst your tube or valve.

Doc, go for foot pumps with integrated pressure gauge. They cost around Rs.500/- and they come along with an adapter to suit your bicycles valves. You can use them on your car and motorcycle as well.
edit : The only drawback when using in old type bicycles valves is that the gauge will show correct reading momentarily when the rubber valve tube opens. And one more thing - the neck of the valve in your bicycle is misaligned. You will have to tighten the lower ring.

Yup, thanks Arun. Been riding it like that for some time now. The lower ring is fully tightened against the rim.
I'll have to get the tyre deflated and the tube repositioned by removing the tyre bead from one side because I tried doing it by removing all the air and pushing the valve into the tyre after loosening the check ring but its not happening.
P.S. Discovered a totally new kind on slow puncture last week. My front tyre was losing air very slowly (I could feel, even hear, it becoming softer on the ride) and would become completely soft over about 2 days.
Finally the puncture was traced to the metal valve housing that is fixed (bolted) to the tube. The actual metal tube was leaking tiny air froth/bubbles from a micrometer split in the casing body (not the joint). First time I've come across this type of puncture.
+1 to Adrian for foot pumps with pressure gauge for filling up to an exact pressure value. That got me thinking. I may get one for myself if it has all the required adapters!

I read somewhere that inherent to their design, foot pumps cannot effectively fill to or beyond pressures above 50-60 PSI. Not a roblem for cars or bikes, but some cycle tyres (especially the thinner they get) need quite a bit more.

+1. Stay away from foot pumps. Been there done that. Foot pumps are useless if you want to go beyond 50. Better use floor pumps of bicycles. Or if you don't want that effort, then buy a mini compressor that can run using car cigarette lighter port.

You have PM bro. Help urgently needed please.

Thanks again. I check with Surender cycles, he quoted 1200 per tyre!! Was a bit shocked since I did not expect it to be so costly. Is this the correct price?
He also suggested an alternative in Schwalbe (he could not remember the details) @1100 INR per tyre.
Any suggestions or alternatives?
Thanks a lot doc and shipnil. You saved me from the disappointment!

Well; those are
imported tires.
I remember paying a similar amount.
Money well spent; I must say! :)
