[PSUBS-MAILIST] Oil Compensator

[Alan via Personal_Submersibles]

Jon,
when I did my sub I bought a lot of fittings & adapters from a plumbing merchant 
& when I couldn't find it there I went to a hydraulics repair shop. There wasn't anything they couldn't do. Most of the fittings for the ambient system were put together with thread tape.
For stainless I went to .... can't remember!
   On Cliff's project page he has had made up a fitting with a small port in it for
attachment of a smaller compensation hose. This is a tidy way of doing it but was probably expensive to get machined. You may want to do similar but just drill & tap the side of an an existing fitting & fit a small barbed elbow in it. Then pot the wires down to
that point.

I'm having a hard time finding a supplier of 1.375 inch I.D. hose which should be able to fit over the shaft knob after heating and some persuation, should I decide on an air compensation for the motors.  In lieu of finding some inexpensive tubing of this size, are there any off-the-shelf nipples of the correct thread that be threaded into the shaft knob to reduce the hose size?
