Definitions

• the invention relates to a sanitary insert for use in a fitting outlet, the sanitary insert having at least one at least partially elastic sealing element which, when the sanitary insert is in the fitting outlet, seals an area outside a flow path.
• the sanitary insert can be designed as a jet regulator, for example.
• Sanitary inserts of this type are already known. Faucet outlets are usually equipped with insert parts of the generic type in order to provide an emerging water jet with the desired properties.
• Sanitary insert parts are wearing parts that have to be replaced regularly, as their functionality is limited after a while, e.g. due to contamination. Replacement inserts are usually sold loose in packaging. It happens again and again that the sealing element becomes detached from a housing of the insert part. This often leads to the problem that a user who inserts the insert part into a fitting outlet inadvertently does so without the separated sealing element. Under certain circumstances, the sealing element can also have to be arranged in a certain orientation, so that the user can therefore install the sealing element incorrectly. In both cases, a malfunction and, in particular, leakage due to escaping water can ultimately occur.
• the object is therefore to provide a sanitary insert part with improved usage properties.
• This object is achieved according to the invention by a sanitary insert part having the features according to claim 1.

• the at least one Holding section protrudes from the squeezing section radially inward and / or in the flow direction, in particular is formed thereon. This has the advantage that the pinch section required for sealing is spatially separated from the holding section.
• the at least one fastening element preferably the pin, is arranged at least partially within a flow path through the sanitary insert.
• the at least one fastening element preferably the pin
• the at least one holding section is designed circumferentially and / or as an undercut.
• an edge that can be clamped and / or acted upon can be formed in order to be able to hold the sealing element better on the housing, in particular without the pinch section for fixing the sealing element being jammed on the housing.
• the at least one pinch section and the at least one holding section are made from the same material.
• the sealing element can preferably be designed as a sealing ring.
• the invention further relates to the use of a sealing element with at least one pinch section and at least one holding section spaced apart from the pinch section, the at least one pinch section, preferably exclusively the at least one pinch section, for sealing a transition from a fitting outlet to a sanitary insert, in particular as described herein and / or claimed, is used, the sealing element being fixed to a housing of the sanitary insert by the at least one holding section, preferably exclusively by the at least one holding section.
• the sealing element forms an axial seal between the fitting outlet and the sanitary insert part.
• the axial seal can preferably be designed in that an upper sealing surface of the sealing element contacts the fitting outlet and / or a lower sealing surface contacts the housing of the sanitary insert, in particular rests on it in a circumferential sealing manner.
• the invention finally relates to the use of a holding section, which is formed on a pinch section of a sealing element of a sanitary insert, for preferably positively locking the sealing element on a housing of the sanitary insert during transport into its position of use.
