Dormakaba 033-508931-K – Frequently Asked Questions

1) What exactly is the Dormakaba 033-508931-K part?
It's the inside housing gasket for Dormakaba mechanical locks, a genuine OEM sealing component that sits within the inside housing of the lock assembly. It is not the housing itself and not a complete lock, just the gasket that keeps the seal at the inside housing. Ordered under part model 033-508931-K and supplied five gaskets to a package.
2) Which Dormakaba locks does the 033-508931-K inside housing gasket fit?
It's specified for Dormakaba mechanical lock assemblies that use an inside housing gasket, and the correct way to confirm fit is by the part number itself: if the exploded parts diagram or service sheet for your lock calls out 033-508931-K, this is that gasket. Sourcing by part number avoids guesswork, since the gasket is dimensioned to one housing.
3) Is the 033-508931-K gasket sold individually or in a pack?
Five per pack. The 033-508931-K ships as a 5-pack of inside housing gaskets, so a maintenance shop servicing several openings gets spares in one order rather than buying singles. There is one orderable configuration, so there are no size or finish choices to specify.
4) Will an aftermarket gasket work in place of the Dormakaba inside housing gasket?
Stick with the OEM part. The 033-508931-K is manufactured by Dormakaba to the original specification for the inside housing of its mechanical lock assemblies, and a gasket that seals the inside housing has to match the housing footprint exactly to seat correctly. Substituting a generic gasket risks an incomplete seal on the interior side of the lock.
5) Is this Dormakaba gasket a commercial-duty part or for residential locks?
Commercial. Dormakaba classes the 033-508931-K as a commercial door hardware component, intended for mechanical lock service in buildings like offices, schools, hospitals, government facilities, warehouses, retail, and multi-tenant residential properties.
6) Why would I need to replace the inside housing gasket on a Dormakaba lock?
The gasket keeps the seal between the inside housing and the door face. Once it hardens, compresses, or tears, that seal is gone and the interior side of the lock is open to moisture and dust, which is why Dormakaba lists it as a replacement part rather than a permanent component. Swapping it during a lock rebuild restores the original seal without touching the rest of the assembly.
