What This Kit Does
The Siemens 3RK1901-3LA00 is a conversion kit for user modules in the 3RK1 application module family. One kit contains a complete set of seals made of Viton and fixing screws made of stainless steel, letting you retrofit or upgrade the environmental sealing of an existing module without replacing the whole assembly. The Viton seals hold up against aggressive media and elevated temperatures better than standard NBR — useful if the module sits in a washdown zone or near chemical vapors.
What the Kit Contains
The kit is a conversion kit for user modules. Each kit includes a complete set of Viton seals and stainless steel fixing screws. The stainless steel screws resist corrosion in humid or washdown environments, and the Viton seals maintain their sealing integrity where standard elastomers would swell or degrade. This is a field-installable upgrade — no need to pull the module off the DIN rail to swap seals.
