    Did you ever give any thought to using pvc plumbing parts?
Schedule 40 DWV (drain-waste-vent) is commonly available and
usually rated at well over 200 psi (plenty for the 4 atmospheres
you can dive to on air).

Pressure ratings of pipe fittings, metal or PVC, are intended for
internal pressures not external.  The PVC might be able to sustain 4
atmospheres externally, but not because it is rated at something over
200 internally.
