Product information "LUNT O-ring 32mm for Pressure-Tuner at MT & THa solar telescopes"
Spare part for Pressure-Tuner of MT and THa series H-alpha solar telescopes from LUNT SOLAR SYSTEMS

Two rubber O-rings are installed into the Pressure-Tuner of Lunt Solar Systems solar telescopes to seal the air-pressure tuning system. Over time, the rubber of this O-rings can age and become porous, whereby the air-pressure can then no longer be maintained. When this happens, a old O-ring can be replaced by this spare part. The replacement is simple and can be done by the user. Installation instructions can be found here under the tab "Manuals" as a PDF file for download.

Please be sure to note:
Depending on the production series, the diameters of the Pressure-Tuner pistons can vary slightly. There are pistons for O-rings with 32mm inner diameter and 40mm outer diameter, and pistons for O-rings with 34mm inner diameter and 42mm outer diameter. Please check the diameter of your old O-rings, this spare part is an O-ring with 32mm inner diameter and 40mm outer diameter.
If you need the larger O-ring with 34mm inner diameter and 42mm outer diameter, this is the spare part with item number 0558340.
The LS50THa telescopes have Pressure-Tuners with smaller diameters, for these you will need replacement O-rings with item number 0558320.

After replacing a O-ring, the piston and cylinder of the Pressure-Tuner can be re-greased with grease available under item number 0558350.

FEATURES
  • Inner diameter: 32mm
  • Outer diameter: 40mm
  • Cannot be used separately, only as a replacement part on the Pressure-Tuner of MT and THa telescopes from Lunt Solar Systems.
  • It does not matter what blocking-filter is at the MT or THa telescope.

LUNT Grease for Pressure-Tuner at MT & THa solar telescopes
Spare part for Pressure-Tuner of MT and THa series H-alpha solar telescopes from LUNT SOLAR SYSTEMSFor example, if the O-rings have been changed on a Pressure-Tuner of a Lunt Solar Systems H-alpha solar telescope, 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 threads of the brass cylinder on the Pressure-Tuner. It keeps the Pressure-Tuner running smoothly and seals it.Please note:Do not use too much grease inside the brass cylinder. The grease must not get into the air passage at the bottom of the brass cylinder, otherwise the Etalon could be damaged in the worst case.FEATURESLithium grease with Teflon contentVery good sealing propertiesHigh adhesion and good corrosion protectionTemperature stable from -20 to +120° CelsiusConstant viscosity during temperature fluctuationsSCOPE OF DELIVERYSpare part: Grease for Pressure-Tuner of MT and THa H-alpha solar telescopes from Lunt Solar Systems
