A housing comprises a first housing part, having a first bearing surface for a first contact surface of a sealing ring, and a second housing part, which can be screwed together with the first housing part and has a second bearing surface for a second contact surface of the sealing ring. The first contact surface of the sealing ring is produced from a first material having a first coefficient of friction in relation to the material of the first bearing surface, the second contact surface of the sealing ring is produced from a second material that has a second coefficient of fiction in relation to the material of the second bearing surface, and the first coefficient of friction is smaller than the second coefficient of friction.
