Great valves for the price! Get these instead of the premium brands!

Easy to install and, so far at least, properly functioning, these valves were installed on wide rims for 2.8 width tires, using Gorilla Tape to seal the rims for tubeless conversion. No leakage, and no clogging, as yet; but its only been a week, so I cant yet comment on any long term experience with them.

Product is great, as expected

These are working very well in my WTB i35 tubeless 2.8 set up, the rubber O-rings are a plus to get that extra seal.

I used a pair of i72 Tubeless 40mm Presta Valve Stems to convert my MTB to tubeless. The rims I converted were not tubeless ready & had schrader to presta valve hole adapters. These adapters are like “collars” that fit into the holes that are sized for schrader valves & have a split in them to allow for compression/expansion when installing. This split allows for a massive air leak. These valves, along w/2 layers of Stan’s rim tape & Stan’s NoTube sealant, successfully sealed & converted my MTB to a tubeless setup. The valves came w/their securing nut & o-rings. These tightened down & seated securely. The cores looked & functioned properly, no issue w/removal, installation, opening or closing. Both my pump & gauge also worked w/the valves properly. I have not had any issues w/them gumming up or sticking because of the sealant. Overall, I am very satisfied w/how these valves have been functioning. Thank you for taking the time to read my review, I hope you found it helpful.

I like these better than the Stan’s brands because they have a rubber gasket under the washer that threads onto the stem. It helps to keep it tight.

These are better than the Stans valve stems. The extra o ring seems to help seal the rim up from air leaks. They also seem physically more robust.

Bought new wheels and tires, and I needed stems. These were reasonably priced. I had no issues with them at all. The included core remover is also a nice touch.

My tubeless tires and wheels worked great for years but the integrated rubber liner and valve stem developed a leak where they were fused together. I added new tape around the wheel, rotated the rubber liner, poked a new hole in the liner and installed these valve stems in place of the old, fused ones and it went in perfectly. It has been a couple of months now and the tires have held the same air pressure the whole time. Job done.

Great worked as expected
