I have acquired 4 Sperry marine gyro compasses, which I am refreshing. Part
of the task is thorough cleaning and the replacement of the suspension oil
in the gyrosphere, as well as complete recalibration. According to Sperry,
the suspention fluid is a blend of Halocarbon 6.3 oil (www.halocarbon.com )
and Dow Corning 200 silicone 1 centistoke fluid at a ratio of 6 to 1. So I
asked for a quote for 10 liters of this Halocarbon 6.3 oil. I just received
a quote of $72.10 per pound, which is sold in gallon containers weighing 16
lbs each. This equates to $288 per liter I think. My question to you all is
should I be so shocked? Do you know why this is priced so high? Thanks in
advance.

It sounds about as pricy as synthetic
vacuum pump oil. Small market, large
R&D investment, the people that need it
are willing to pay the price.

If this is the same as Krytox pump fluid used for oxygen service,
do not be suprised. That stuff is *expensive*.

We used to use similar in seal legs for d/p cells on orifice flow
meters (I dislike orifice flow meters). It's very inert, very dense
oil, which helped it stay put in seal legs. Ours was expensive back
in the '70's.

You might want to search for cashew oil (caju). I remember it being used for
very close tolerance lubrication at NASA.

Hi Steve,

I've been thinking about your pricey predicament. Perhaps the best option at
this point would be to take them to a shop that refurbishes these gyro
professionally. They're probably the only one who purchase enough of this
stuff in volume to make the price bearable. You may also consider sending
them out of country; it might be cheaper to have them done in the US.

Regards,
Michael
