Schleicher pneumatic tube plumbing question

9B,

I assume by now you've read my post describing the problem.

My 29 has 3mm OD (polyethylene?) tubing going from the fore end of the
area under the glare shield to under the seatpan. After reading yours
and GY's accounts, my guess is that the factory addressed the problem
my using the smaller polyethylene tubing for this part of the glider,
which does much better under heat and stress than the larger tubing.

It came from the factory with adapters that step the smaller tubing up
to the larger size, both under the seatpan and behind the instr panel.
They're just like the connections on my MH EDS controller, where you
depress a flat ring to disengage the inserted tubing.

I'd like to know the proper nomenclature for that tubing and adapter.

Glider is back home and flies great!

I think the fitting may be referred to as a "push fitting". Perhaps
because all you have to do is "push" the tubing into the fitting.
