## Abstract

A fluid housing of a fluid treatment system of a fluid system has a housing part of plastic material that is provided with a receiving chamber for accommodating a fluid treatment component; an installation opening, closable by a closure housing part, for installing the fluid treatment component in the receiving chamber; and a housing connecting section to connect the housing part to the closure housing part. A housing fastening section is provided with which the fluid housing can be fastened to a holding component of the fluid system. An insert is at least partially introduced into the plastic material of the housing part. The insert is provided with a reinforcement region extending with sections thereof in the housing connecting section and is further provided with fastening region extending with sections thereof in the housing fastening section. A fluid treatment system with such a fluid housing is provided.

wherein the at least one insert comprises at least one fastening leg connected at a first end to the at least one annular reinforcement region of the at least one insert, the at least one fastening leg embedded, at least in sections, into plastic material of the connecting flange of the at least one housing fastening section.

### Claim 2

A fluid housing of a fluid treatment system of a fluid system, the fluid housing comprising:
at least one housing part of plastic material, wherein the at least one housing part comprises:
at least one receiving chamber arranged in an interior of the at least one housing part and configured to accommodate at least one fluid treatment component for treating a fluid;
at least one installation opening, closable by a closure housing part, enabling installation of the at least one fluid treatment component in the at least one receiving chamber; and
wherein the at least one housing part has at least one housing connecting section surrounding the installation opening of the at least one housing part and configured to connect the at least one housing part to the closure housing part;
at least one housing fastening section forming a connecting flange protruding radially outwardly from an outer side of the at least one housing part and configured to fasten the fluid housing to a holding component of the fluid system;
at least one insert comprising metal and/or a composite material, the at least one insert at least partially embedded into the plastic material of the at least one housing connecting section of the at least one housing part, wherein the at least one insert comprises:
at least one annular reinforcement region of the at least one insert is embedded into the plastic material of the at least one housing connecting section such the plastic material is arranged on both radially outer and radially inner sides of the annular reinforcement region of the at least one insert; and
wherein the at least one insert comprises at least one fastening leg connected at a first end to the at least one annular reinforcement region of the at least one insert, the at least one fastening leg embedded, at least in sections, into plastic material of the connecting flange of the at least one housing fastening section.
