It is suitable for the modification and replacement of the valve inner nozzle and the vacuum tire nozzle lock nut.
After the replacement, the locking force is greater and the air tightness is better. The unique sealing ring can not only improve the air tightness, but also prevent the nut from loosening and wheel hub damage.
Portable multifunctional wrench. Can be used to install or remove Presta valve core, nut, extension rod.
The lightweight nut is made of high-grade aluminum alloy. Which greatly reduces the impact on the wheel balance and enables the driver to obtain better competition results.
Package Includes: 2x Nut, 2x Sealing ring, 1x Multi-function wrench. Note: When installing, first place the Sealing ring, and then tighten the nut.

As described
These are exactly as described. They work well and are fairly inexpensive. If you’re on the fence, just place the order.

Good Value
Good presta tire valve nut, o-ring, and tool, costing much less than others. Would recommend!

Decent
This item threaded on easily enough, and seems nice. The problem is they will not fit schrader rims, using presta valve the nut washer is smaller then the schrader hole in the rim.

not very good
I bought these as a cheap alternative to the bigger/ nicer/ more expensive Problem Solvers version. I don’t like that you need a special wrench to tighten them and 1 set was slightly oversized & would slip on the presta valve threads.

Exceptional Product
Works as intended. Don’t forget to place the tool into your Bike’s Tool Kit when out and about. Highly recommended!

Too big for Presta Valve Stems
I got these to try and seal an imperfection in one of my rims. The valve stem hole doesn’t sit exactly right without overtightening the lock nut. But if you do that, you cannot remove them with just your fingers. I was hoping these would fit that bill. Nope. They’re too big for presta valve stems. I can literally slide them on and off. No way to tighten since they don’t thread properly. I would return them but I damaged one before I realized they just weren’t grabbing the threads. Thankfully, it’s only a $10 mistake.

Only 1 works
Just received my set and when I installed them only 1 was able to thread and stay in place. So these are kind of useless.Another commenter had the same issue and I should have listened.If both worked they would be a 5 star product.It is a roll of the dice on this one

Very compact but well made
This little kit is great. Its aluminum so its durable (vs the plastic crap you usually get w/ valve and stem kits). Its also tiny, so it fits in my on bike kit. A backup nut and rubber washer is bonus as you usually don’t get those with valve and stem kits either.

Wrong item ordered
Looks like a good device, did not open as the item I thought I ordered had external antennas but the unit received did not show it on the package. Looks like a good possibility for longer range outdoor WiFi.

Quality nut to secure the tire valve to the rim
I like the wrench and how easily these are to tighten the tire valve to the rim (tool included).
