Due to a slight 'administrative error' I now have 3 rolls of PTFE gas tape.

Is this just the same as normal PTFE tape but thicker? OK for general
plumbing use?

Its ok to use, but not as easy to work with I find.

(might be good though when you want to set a parallel thread fitting at
a particular stopping point (e.g. like an outside tap on a wall fitting)
which can take yards of the normal stuff!)

I use it all the time in preference to the thinner stuff for gas,
compressed air and oils. Much easier, you only usually need one or two
turns to make a sound joint.

But recently I've taken to Loctite 542 thread sealant which is
absolutely brilliant stuff - you can assemble threaded fittings finger
tight pointing where you want them, and within minutes you get a sound
seal and good mechanical fixing that can be undone later.

What is it like in parallel to parallel threads?

Very good - they say only use it on parallel threads up to 1/2" BSP
but I confess to using it up to 1" sucessfully on a 15Kw water chiller
recently.

And it's tight to hydrogen!
(This is a very non-trivial point if you're plumbing laboratory
machines.)

Even 200 Bar H2!

I think our stock bottles only come out at about 1800psi (about 120
bar?), but I don't see any reason for concern at higher pressures. Since
the bottles weigh about 80kg each, but have to be shipped in a 800kg bottle
rack, we tend to send out several bottles at once. 3 bottle in a rack
provides redundancy better than one bottle of 3 times the volume or
pressure), and redundancy is important against some idiot checking bottle
pressure by opening the bottle valve without a regulator/ meter in the
fitting (it has happened, repeatedly), or a novice being unable to undo the
regulator fitting with a 10" spanner, so he gets a bigger spanner, then a
bigger one, then a cheater bar, then shears the regulator fitting out of
the bottle valve (poor boy didn't know about left hand threads).

That's a good point, why do gas cylinders / fittings etc use left handed
threads?

Only 3? We had 12 cyl MCP's until the fire....NOT H2 related BTW.

Definitely, and especially where tolerances of threads etc. seem to
result insome cases in poor results for ordinary tape, such as radiator
tails and HW cylinder fittings
