Looks like the answer is no. This is from the Dupont website:

If somebody offers to sell you “Teflon tape” when you need plumber tape (or thread seal tape), they are wrong, mistaken or — worse — trying to mislead you. To help you make an informed purchase, you should be aware that no plumber tape is authorized by DuPont to be sold as “Teflon tape”.

Less joints is always good. McMaster (and others) sell some t-joints that are threaded on one side and quick connect on the other sides. Being careful with your joint and connector selection will let you reduce the number of joints in general which leads to more reliable pneumatics all around. I cringe at all the little stub joints used to bridge between fittings. Every one of those is a potential failure waiting to happen.

Do not consider the pneumatic quick connects to really act as quick connects, at least not on the final robot. The tubing and even the connectors start to wear with repeated insertions. Try to limit the number of times you disconnect and reconnect these joints to avoid creating a lot of small leaks that are difficult to find. On the finished robot, it is not over cautious to re-trim the ends of the tubes each time you remove and reinsert them. If the tubing gets too short replace it completely. Many students seem to want to pop these connections on and off way too much for a trustworthy connection.
