do these tubes have removable valve cores?

They look like any other brand of prestas I've used, though I've never had to remove the core.

yes...they are tubeless ready...a little hard to seat with a floor pump. I always seat them with CO2.

In most cases yes. The newer bladders are easier to deal with because you can remove the entire tube assembly and pull off the bite valve. In my case, I had winter tubes which have a hard rubber casing around the valve which is impossible to switch out. I had to buy an entirely new tube/valve assembly.

Yes the center core is included with these, but be warned that these center cores are fragile. Mine came with a broken center core upon delivery. And I have broken one during removal of the filter during cleaning.I would recommend using a good multipurpose plastic glue ( you will find it in the plumbing section at, Lowe's, Home Depot), during assembly. As the center core goes together with about 6 different parts.

No check valves. I was also surprised to learn that the threads are British pipe threads, which is neat impossible to find in the US. It is, however, a quality product and maintains the set temperature.

It should. This kit includes several sizes of the extraction tools but not the valve cores themselves. I ordered the Mastercool #91337 valve core assortment kit separately. The important thing to note, though, is to take a careful look at the charging port on your air conditioning line after removing the dust cap. If you don't see the familiar pin of a valve core but instead see a smooth surface of a rubber ball, then don't attempt to remove anything with this kit. It is not a valve core. It's a different kind of charging port.

Yes. They areImbedded in the manifold. Just put it in place and bolt it down.

No tubes needed. You can get valves from just about any auto parts store really cheap. They pop right in easily.

Yes, the coupling is removable, the issue would be if the threads match on the new valve to the older part you want to use. From looking most of these seem to be pretty universal.

Yes. All the 700C sized wheels I've ever seen have a presta sized valve stem hole. I had to do some very minor trueing.

They do. And you'll need to be sure to get tubes with 60 mm valve stems. Even that's a little short, so you may want to spring for valve extenders.

Yep, they have valves. But they are about as easy as you get w/ sippy cups. Sadly, mine were a little leaky.

They are listed on the back of the tube. I don't have the box, so I can't remember if they were on the box as well.

I'm not sure, since they are inside my tires at this point. But I will tell you, that the valves aren't long enough. I need to change my review of the product because since I wrote my review I have had all sorts of problems with those tubes. They are NOT puncture proof, and even though I have repaired ALL punctures, it still won't hold air. As far as the valves, they are far too short. If I use an air compressor, I can inflate the tube. But if I'm just trying to use a hand-pump, there is insufficient valve exposed to correctly connect to the pump. I wouldn't purchase this product.

There is no core. Instead you use that screw in the middle as a piercing valve. Anyway, if you're talking about an automotive R134 hose, you can get the "R12 to R134 adapter" at most auto parts stores, or here on Amazon. Throw away the cap and replace with that adapter that fits your hose. (There's a high side that won't fit and a low side that will) It has its own Schrader valve. WARNING: DO NOT think that just because your appliance is R134, you just charge to 35 or 50 PSI. Some appliances run at 2 to 5 PSI. Too much and it won't cool.

Yes the valves are included with this item...it's about the only item in the DELTA collection that does.

I think they carry both valve types, but beware, I have gotten many flats with theses tubes. I prefer Mr. Tuffy's.
