OK, but I've never heard of using heat for pex. I just tried to find

I found a Flair-It ad on youtube.

I was surprised at their spelling of "flair." They don't know how to
spell "plumbing," either.

A selling point is that you need no tools. Their connections went
together and came apart so much more easily than in other demos, that I
think they must have warmed the tubing with a hair dryer, if it was PEX.

They made a loop with several connections, loosened the nuts, and
demonstrated that it wouldn't leak at 100 psi. I'd say they slide
together more tightly than other fittings. That could pay off in
environments where nuts might come loose.

A moron video. Polybutylene fittings are not PEX; nor are the
polybutylene fittings used on PEX.

They kept saying PEX, and you say they're for polybutylene? Flair-It
didn't become available until polybutylene had been off the market ten
years.

It it bothers you that Flair-It fits tightly enough to hold 100 psi
without a nut, you must not have heard of the Wirsbor/Uponor system.
The fittings are so tight that you need an expander costing hundreds of
dollars. You expand the PEX and slide it easily over the fitting. In
ten seconds you have a connection with a 25-year guarantee, the best in
the business.
