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 set of gasket can replace the on the main brake cylinder form 6 or 7. It is very likely that this type of cylinder is installed in the Duo Discus (but not in the x or xL), some Nimbus-4(D), as well as in some retrofitted Nimbus and Janus.

It do not work with the rectangular brake cylinder installed on some gliders (Ref: B40-1014).

This tension spring is used to maintain the flap handle on the right position. 

On the Janus B and Nimbus-2, it is located near the front seat handle.

Originally, the Janus C, the Nimbus-3D and the Nimbus-4D are using another spring that looks very different (ref B40-2417) and that is located on the back seat cockpit wall. However some gliders have been modified and they are now using this flat spring but near the spar bridge.
