Special air valve head— Dunlop
Most basic pumps here in China come with this adaptor for Dunlop valve. I have never seen this before in the States. I dont have any Dunlop valve tubes, but
I am tempted to buy a set of tube with Dunlop valve just to try out this adaptor.
It looks very easy to use.
My bike use 26x1-3/8, so it is low pressure.
My petpeeve is the Schrader’s pita in dealing with difficulty of putting/removing the valve head. So this adaptor might just reduce alot of aggravation.
Any use this kind of adaptor before? How good does it work?

Don‘t know about that adaptor, but dunlop valves work perfectly with presta adaptors.

Where I live Dunlop is common as well as preta. Both usually works in the same pump head without an adapter. Dunlop is as easy to pump as presta but doesnt have the annoying valve stem that bends.

Tthe biggestproblem is that the thread on the Dunlop valve is very course. So it quickly wears out the rubber in the Presta head.

without an adaptor, it works only marginal, to use a Presta head on a Dunlop valve. There is not enough surface on a Dunlop valve for the Presta head to grab. On a cheap pump, this means leakage. On a quality pump, this works okay for low pressure tires, but...

For reference ive been using dunlop and presta for as long as I can remember and every pump i ever owned, track or hand, works or worked just fine with both. I do own a few presta to dunlop adapters, that i never use. The benefit is they protect the valve stem from bending, which is useful with a hand pump, but the down side is they tend to leak.
A useful adapter for you kit, is a presta to schrader adapter, enabling you to pump your presta vale bike at a gas station.

Why even ask if all of a sudden you are the expert? :-)

I think there are two different types of “adaptors.”
- the screw-on-to-valve type....this is type you commonly find in LBS... you screw the adaptor onto the Dunlop valve...I haved used this type of adaptor, and it works good. But i dont like the looks ...real ugly. So I am familiar with this type and not interested in it.
- the attached-to-the-head type...this type of “adaptor” is the one I posted the picture above in post 1. It has a spring clamp. I have never seen this kind before until now. So, this the the adaptor I dont know much about, and want to know more.

Hello MTB_Addict. Once, Raleigh owned Dunlap. They were on the 3 Speed Sports style of bikes. Were never what, we'd call today a high pressure tire. Was like when Schwinn build their own size wheels. Often on Stingrays etc & the Electro-Forged frames. Built in Chicago. The S Tires they built those too. Any long in business might help you find anything still around for Dunlap valves. cheers,,
