LUNT O-ring for Pressure-Tuner at LS50THa solar telescopes

Spare part for Pressure-Tuner of LS50THa H-alpha solar telescopes from LUNT SOLAR SYSTEMSA rubber O-ring is installed into the Pressure-Tuner of Lunt Solar Systems LS50THa solar telescopes to seal the air-pressure tuning system. Over time, the rubber of this O-ring can age and become porous, whereby the air-pressure can then no longer be maintained. When this happens, the 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 for download.After replacing the O-ring, the piston and cylinder of the Pressure-Tuner can be re-greased with grease available under part number 0558350.Please note that this spare part can only be used on the Lunt Solar Systems LS50THa H-alpha solar telescopes. If the problem occurs on the larger THa or MT series telescopes, the larger O-rings with part numbers 0558330 or 0558340 must be used there.FEATURESInner-diameter: 31mmOuter-diameter: 39mmCannot be used separately, only as a replacement part on the Pressure-Tuner of the LS50THa telescopes from Lunt Solar Systems.It does not matter what blocking filter is at the LS50THaSCOPE OF DELIVERYSpare part one O-ring for pressure tuner of LS50THa
