I am looking for the best lubrication to be used in a thermal actuator where a rubber *Viton, or Nitrol plug will be placed inside a cylindrical 360 Half Hard Brass "guide" with a stainless steel piston placed ontop of the plug.

As the moving force of the thermal actuator pushes the plug, the plug will push the piston, its quite simple.

We are lubricating currently with a standard grease mixed with graphite.

Can anyone suggest a good lubrication vendor who may be able to point me in the direction of a superior lube than what we are using now?

Any help would be much appreciated

Thanks

I don't about your application but the best grease i've found over the past 15 yrs is SE-100 its a calcium sulfonate grease its we were using a company is called certified labs grease and we didnt have breakdowns.well breakdowns every year and a half and we've been using the SE-100 now for 3 and a half yrs and no down time yet its saving us tons of money in downtime. it's steward enterprise oil in wisconsin ask for james. they'll help there nice fam owned co..
