Replacement part for Pressure-Tuner of LUNT SOLAR SYSTEMS MT and THa series H-Alpha solar telescopes
Two rubber O-rings are installed in the Pressure-Tuner of Lunt Solar Systems solar telescopes to seal the air pressure adjustment system. Over time, the rubber in these O-rings can age and become porous, making it impossible to maintain air pressure. An old O-ring can then be replaced with this spare part. Replacement is simple and can be done by the user. The installation instructions can be found here under the "Instructions" tab as a downloadable PDF.
Please note:
Depending on the production series, the piston diameters of the Pressure-Tuner pistons may vary. There are O-ring pistons with an inner diameter of 32mm and an outer diameter of 40mm, and O-ring pistons with an inner diameter of 34mm and an outer diameter of 42mm. Please check the diameter of your old O-rings, this replacement part is an O-ring with an inner diameter of 34mm and an outer diameter of 42mm.
If you need the smaller O-ring with an inner diameter of 32mm and an outer diameter of 40mm, this is the replacement part with item number 0558330.
LS50THa scopes have Pressure-Tuners with smaller diameters, for these you need replacement O-rings with item number 0558320.
After replacing an O-ring, the piston and cylinder of the Pressure-Tuner can be re-greased with the grease available under item number 0558350.
