Schrader20055 TPMS Nickel Plated Valve Core - Pack of 100

These are the real deal, compared to a german OEM valve they look nearly identical with similar or superior build quality.

Like almost everyone else, I didn't need 100 cores right off, but with a dozen-ish bikes, a half dozen-ish motorcycles and a backyard chicken flock being watered by auto watering bowls, paying nearly a buck for a core at the auto parts store just wasn't economical.These are great quality and probably about a decade-lifetime supply for most folks. Mine came packed in a single bag. I didn't count them but it looked like 100 (actually it looked like "WTF do I need this many cores for?"), but to be honest, replacing the crappy rotted cores in a couple bikes made it a worthwhile purchase simply because it meant that I didn't need to put air in every time I didn't ride that bike for a couple weeks.Bonus: They work great on the Little Giant type auto poultry watering systems. When the fount starts acting up I remove the bowl, unscrew the core and cut the water on for a few seconds to flush the system (the lowest point is the valve core in my system), then I put in a new nickel plated core and carry on.

Small 4 wheelers are tough on Schrader valves ! Have not found any that were defective ! Thanks !

I have basically a bike shop in my garage and do all my friends and neighbors work so these were a neccesity. There's not much to say, I haven't had any problems and I've probably used 25 of the 100. The biggest thing I use them for is replacing a Slime victim- if you don't do it right when releasing air and there's too much Slime in the stem it'll clog those things up to unusable.They seem to be made well- I didn't count but it looked like a hundred and I believe they arrived in a timely manner. If you need valve cores, just get them in bulk, these will last you a long time.

.These Schrader 20055 TPMS Nickel Plate Valve Cores are perfect replacement valve cores for the woefully inferior cores that come with Slime-filled inner tubes (located elsewhere on these Amazon pages.) While the advantage of having the Slime inner tubes is excellent for puncture-resistance, Slime failed miserably on the selection of inferior cores for their tubes as they consistently fail or get clogged--even when the bike is stored or filled with air with the valve between the 10 and 2 o'clock positions.So when the Slime cores fail (and they will) have on hand these as backups to replace it.Stay Safe,...GhillieMan

When you need one great to have. know people that bend valves not familiar with air chucks, nice to help them out of a new problem they got into. Many portable air compressors have poor air chucks that create Schrader valve issue too.

I was going through valve cores pretty fast because my wife's recumbent trike has "Slime" tubes on it. I had been buying a package of them at Walmart that came with a core valve removal tool. But I have so many of those tools now that I went looking for just the cores. This product was just what I needed. The cores seem well made and the couple that I've used are working just fine so far. If you use a lot of cores this is the product for you.
