Product description

A rubber O-ring is built into the pressure tuner of the Lunt Solar Systems solar telescopes to seal the air pressure tuning system. Over time, the rubber of this O-ring can age and become porous, which means that the air pressure can no longer be maintained. The old O-ring can then be replaced with this spare part. The replacement is simple and can be carried out by the user.

After replacing the O-ring, the piston and cylinder of the pressure tuner can be re-greased with Lunt Solar Systems Spare Teflon-Lubricant for O-Ring PT-Piston.
