Notes

A standard 2 in tee holds about 390 mL of gas. Two inserts fill it: a run plug (slid in from a run end) and a branch plug whose saddle-shaped bottom sits on it. What is left is a Ø12 passage from the hot spool's side up to the power cylinder, the displacer rod's Ø6.6 bore and a Ø4 hole to the gland cap's ports.
Gas left in the tee and its joints about 25.9 mL; Ø44 spigots reach through each gasket's lip to 0.5 mm from what they face.
