I was looking for something to use on a pair of Schrader fat bike radrover rims. I like the silicone gasket these come with, I have had no issues with the valve leaking anywhere at all. Rim tape is definitely an important component as well, make sure you poke a small hole smaller than the valve diameter before inserting. Great product!

Seals ok but are very thin cheap aluminum and one broke off first ride. Did brake at rim broke above the nut and right below the valve. If you use these bring a tube . I'm getting stainless steal valves next time.

Nice all metal stems that fit into my rims nicely. Came with 2 cores ,a mini wrench, and stem caps. Also came with 2 rubber washer type gaskets that you affix to the outer rim as pictured in the item description. They quickly curled up around the stem so I’m not sure if they serve a purpose since the inner part of the valve stem is rubberize to seal from within. I would recommend these as they are not too long or short to fit through a tubeless rim setup. Seem quite durable.

I decided to take the plunge into a tubeless set up and these were the recommended valves. No complaints & would recommend them to friends & anyone else ready to go tubeless!

Came with everything but the rim tape that the nut sits on. Overall great quality and sealed very well.

I could not believe the price of these stems at my local bike shop so I checked Amazon and they were half the price!!! I installed them on my electric Mountain bike and they work great and included 2 valve core removers and caps A++

I’ve never had a valve fail like this- initially I was going to return these as they are quite heavy… but I decided to keep them as they looked fine and I already had them. I cancelled my return.About a month later I couldn’t get my tire to seat- I assumed it was a pump issue and eventually got a compressor to burst the air in. Turns out the issue wasn’t my pump- or anything to do with the air delivery systems.I couldn’t get the tire to seat because the valve had micro cracked along its shaft- allowing air and sealant to seep into the rim itself- I could see sealant and air coming out of all the spoke holes.What a mess.Once I worked out it was the valve that failed- replacing this and seating the tire was easy.I have never had a valve fail this way- the conclusion is that these are heavy and also cheaply made. I do not recommend.
