Yo, 'sup
I need to lubricate pneumatic switch silicon seals with something.
What material do I need?
I have tried valve oil, WD-40, and silicon spray.
All of these make things worse.
I only have bearing grease here left to try.
Cheers peeps
I need the lightest action switches, so am trying to lube

hey thanks-
maybe I need some naptha or transmission fluid. The is also pneumatic oil I remember now. Maybe they have it at the local supply. After being dosed with these petrol based stuffs- I ran some water on it and that was better. It will prolly revert once it's dried though.

edit-the last one I tried was best. The bearing grease works good

Silicone grease might work also.

Thanks Cam-
It will prolly work-
I'm guessing it is the consistency more than the substance.

See user name, exercise imagination.

I made the WTF face when I started reading the thread title.

I'm listening to the original Dolly Parton "Jolene" and tears are in my eyes. Some kinda lubrication is imminent in this colorful life of mine.

What is the switch? What's it look like, what's it used for.

I'm thinking about selling my mod on these Lego switches.
The 2 I have modded are in my pneumatic motor concept.

Inside is a semi-circular silicon cavity, with 2 dot cavities at the ends. When the switch is off, the 2 outs have the dots over them.

So it's a bit OT for KVR, but here is some of my pneumatic play with musical results->

Yeah-I thought there my be some opportunity to make some lewd remarks. Just don't use WD-40 hehe

Lego parts are low friction by default, so maybe the air through the switch is causing a problem? In that case, silicone would be a good choice, but given that it is pneumatic, the lubricant might block flow.

hmm, they are not as low friction as possible by default,
as they r indented.
I have ground off the indents and replaced the plastic weld with 3 3 mm bolt(one is the pivot point),
this means that the side plates can be adjusted depending on how much air pressure there is. ie, at 60 psi there is more friction than at 10(caused by doing up the bolts).
I think silicon sounds good too,
the grease doesn't block the flow.
It is necessary after applying to give the switch a good blow out, or u get grease in the lines.

Thanks mate.
On my 100 PSI unit I will be using these switches->

The friction is now at the minimum, unless the silicon grease is better

Silicone will last longer, as it's bio-inert. I am not familiar with pneumatics, but if you want the grease to stay put it needs to be the right viscocity.

What substance do u use to lubricate silicon seals?
