What is the maximum working pressure of the End DIN 11851 with GZ, with tail for RS clamp, stainless steel, type DZR?

The maximum allowable working pressure of the End DIN 11851 with GZ, with tail for RS clamp, stainless steel, type DZR Format is: 40 bar for sizes DN10âDN40 and 25 bar for sizes DN50âDN100. Operating temperature depends on the gasket material.

Can the End DIN 11851 with GZ, with tail for RS clamp, stainless steel, type DZR be used with other gasket materials to extend its operating temperature range?

End DIN 11851 with GZ, with tail for RS clamp, stainless steel, type DZR: yes - the operating temperature range depends on the gasket material. The fitting itself (AISI 316) supports specified pressures (40 bar DN10âDN40; 25 bar DN50âDN100) and the Ra 0.8 Âµm bore finish improves sealing. To extend temperature limits, choose gasket materials rated for higher or lower temperatures (e.g., PTFE for high temperatures, Viton/FKM for elevated temps, EPDM or silicone for low/high extremes) ensuring chemical compatibility and compliance with food/industry standards. Verify gasket dimensions for the Rd thread/tail interface and confirm pressure/temperature ratings of the chosen gasket with the gasket manufacturer before use.

Is the End DIN 11851 with GZ, with tail for RS clamp, stainless steel, type DZR suitable for cosmetic industry use?

Yes. the End DIN 11851 with GZ, with tail for RS clamp, stainless steel, type DZR is suitable for cosmetic industry use. Reasons: - The fitting is a variant of the DIN 11851 âmilk connectionâ widely used in food, cosmetic and chemical industries, so it is designed for hygienic screw connections. - Material AISI 316 stainless steel (type DZR) offers excellent corrosion resistance and is commonly accepted for cosmetic applications. - Surface finish: premium version hole roughness Ra 0.8 Âµm supports hygienic cleaning and reduces contamination risk (economical version has higher Ra). - Pressure and temperature ratings are adequate for typical cosmetic processing: max working pressure per DIN 11851 is 40 bar (DN10âDN40) and 25 bar (DN50âDN100); operating temperature depends on gasket material selection. - The round Rd thread with large tolerances ensures easy, reliable sealing when used with appropriate gaskets and RS clamp components. Notes for implementation: - Choose gasket material compatible with your cosmetic formulations and required temperature range. - Prefer the premium surface finish (Ra 0.8 Âµm) for stricter hygiene requirements. - Verify gasket and clamp assembly meet your facilityâs cleaning and validation procedures.

Additional information

Material	SS – stainless steel

DIN 11851 end fitting with external Rd thread, with a tail for RS clamp, is a component of the so-called “milk connection,” most commonly used in the food industry for screw connections. It is also utilized in the cosmetic and chemical industries, with many devices and instruments equipped with this connection. The round Rd thread and large tolerances ensure that the connection closes easily. The roughness Ra of the hole in the premium version is 0.8 µm (in the economical version, the roughness value is higher than in the standard version). The maximum allowable working pressure (for the connection itself according to DIN 11851): 40 bar (DN10÷DN40), 25 bar (DN50÷DN100). Operating temperature: depending on the type of material used for the gasket. Material: stainless steel AISI 316.
