Oil Pressure switch and oil thermostat ?

I am going to change my clutch next week, and while the engine is out I am changing the oil cooler seals, oil pressure switch, and thermostat seals.
I have not been able to find the seal for the pressure swith,is it a O-ring or a seal?
All the parts houses below do not have it.
I ordered the O-ring for the thermostat is there a gasket also that has to be changed?
Superman recommended that I use Dow Corning 111 on the o-ring and seals but I can not find the stuff anywhere including Pelican,automotion,tweeks,vertex, any ideas?
Thanks in advance.

You're gonna hafta visit your local airport, or industrial area. One poster said every self-respecting aviation repair or maintenance shop will have Dow Corning 111, and I believe that.

I got mine at a local industrial supply place that makes hydraulic fittings. This stuff is really the cat's meow, so I hope you will be able to find it. It's in a green tube, like a toothpaste tube.

I'm about to replace my thermostat o-ring and I don't believe there is any gasket, other than this.

I don't recall about the oil pressure switch. I replaced the hole thing. I am sure it is not an o-ring. And if your oil pressure switch is leaking, it is probably not from a bad seal. Oil is more likely getting up through the body of the switch, coming out at the top near the spade connector. This is why I just replaced the switch.

Been meaning to ask about the clutch project. This weekend?

Thanks again Superman, I have a freind whos son is a aircraft mechanic he should be able to find the Dow 111 for me.
From looking at the switch your right its only a screw in type with no seal.
I will give you a update when the job is complete.
