Continental Conti Valve Extender (Pack of 2)

Just make sure you buy plumbers tape (about $2 for a roll). Dont trust the rubber washers to hold air in over the long-run -- plumbers table should, though. Although, this isnt specific to the Conti valve extenders -- all valve extenders of this type are like that. ALWAYS BUY PLUMBERS TAPE!

Does its job well. It fits perfectly and holds air.

This work great with deep dish carbon rims. The ridges on the tip also allow a good grip when your filling up with your presta valve pump. Make sure to put on pipe sealant teflon tape before screwing these on for a better seal. This is the 3rd set Ive bought. Also make sure to get the proper length so that you have room to place the pump on your valves stems. I tend to go with a little longer valve extender because I have a 60, an 88 and 100mm different deep rims.

Works really well to bring that short tube valve out far enough to actually put a pump on it!

Dont buy the plastic extenders. These extenders will last.

I found this very easy to install when you follow the directions. Ive used the extender on two tubes. For both tubes, the fit seems correct however when attempting to pump up the tire I meet extreme resistance. Pressure gauge on the pump shows inaccurate results and makes adding air very difficult.

I just return valves. because it doesnt fit for Michelin AirComp Latex Tubes. however this extenders are high-qulity

Good quality no leakage

Works as advertised

great product
