Stainless steel pulp disk
New pulp washer made of stainless steel for sealing windchest trigger wires.
The advantage of this pulp washer is the inner hole of the Liegelind sealing and guide washer, which is adapted to the diameter of the wire. The stainless steel washer has a larger hole (approx. 6.5 mm) and is therefore independent of the trigger wire.
We offer the sealing and guide disk with two different inner holes. Inner holes. Diameter 1.8 mm for wires from 1.5 - 1.65 mm and 2.2 mm for diameters up to 2.0 mm. Another advantage of this type is that trigger wires with threaded ends can be pushed through without any problems. The minimal air between the wire and the edge of the inner hole does not cause any noticeable wind noise. During installation, however, care must be taken to ensure that the hole is not widened by bends such as hooks or a thread on the trigger wire. In such cases, always thread the sealing washer and the stainless steel washer separately and only fix the stainless steel washer to the sealing washer in the wind box.
The pulp disk made of stainless steel with a height of 5 mm is neutral and heavy enough even under problematic ambient conditions. Changes in humidity are not expected to alter the inner hole compared to pure felt, leather or cashmere cloth. To prevent the stainless steel pane from slipping, it must be permanently bonded to the sealing and guide pane. This can be done before or during installation.
The standard diameter of 20 mm with a stainless steel washer of 18 mm is suitable for most trigger pitches. If a smaller diameter is required due to a narrow pitch, we can offer you a stainless steel washer with a diameter of 10 mm and a double height of 10 mm on request. You can then modify the sealing washer with D = 20 mm supplied by us to fit the required outside diameter yourself. Due to the double height, this stainless steel washer has almost the same weight as the standard size.
We generally recommend that you test the windchest before installing all the washers.
