Spare Teflon-Lubricant for O-Ring PT-Piston

If the O-rings on a pressure tuner of an H-alpha solar telescope from Lunt Solar Systems have been replaced, the pressure tuner can be re-greased with this grease. The grease can be applied to the piston with the O-rings and to the thread of the brass cylinder on the pressure tuner. It ensures that the pressure tuner runs smoothly and seals it.

Please note: Do not use too much grease inside the brass cylinder. The grease must not enter the air channel at the bottom of the brass cylinder, as this could damage the Etalon in the worst case.
