Waterballast

This O-ring  Ø32 x Ø3 is used for the water dump valve of several gliders:

• the Duo Discus x and xL,
• all the Arcus,
• some Discus-2c (the system has been upgraded in 2005),
• the Ventus-2cx and the Ventus-2cxa for the inner wing dump system not the outer wing.

This flexible rubber boot is 63 x 39x 39 mm with a 10 mm and a 25 mm opening.

It is surrounding the ballast rod on the wing root of the Discus b, Ventus-2 (SN < 561), Discus-2a and Discus-2b (SN< 234) which have been produced before June 2009. However, some of these gliders might have been retrofitted with the newer system. You can see on the suggested product the other bellow.

It is used for the ballast system of the Nimbus-3, -3D, -4 and -4D. For the Nimbus, the bellow may need to be adapted by cutting the larger end.

It is also used as a sealing around the brake line when crossing the wheel box in all single seaters.

 

This rubber boot is surrounding the water ballast control rod to avoid the water leaking through. It is used in several Schempp-Hirth gliders including the Nimbus-2, Ventus, Ventus-2c, Discus-2c, Duo Discus and the Arcus.

It is 125 x 22 x 22 mm with a 7 mm and a 16 mm opening.

Over the years, other bellows and different combinations have been used. You can find them underneath this description, in the "suggested products", if you want to compare them with the model that you wish to replace.
