FAQ

What is the surface roughness (Ra) of the wetted surfaces?

Standard aseptic fittings like this typically have an internal surface roughness of Ra <= 0.8 micrometers to ensure cleanability and prevent bacterial growth, although this specific part should be measured for verification.

This listing is for the metal union parts only. A compatible gasket, typically made from EPDM, Silicone, or PTFE, must be sourced separately to complete the aseptic seal.

No, DIN 11864-1 (aseptic) and DIN 11851 (hygienic) unions have different thread profiles and sealing principles. They are not directly compatible and should not be interconnected in a process line.
