Sterile Screw Union
Groove nut on a threaded liner. The slimmest version, opened with two spanners.
Sterile Connection
Developed for sterile and hygienic pipelines that depend on smooth product-contact surfaces, reliable sealing and complete material traceability. Suitable for gases and liquids, available in several connection types and pressure ratings.
4connection types available
1.4435BN2 (316L), product contact standard
−200…+260°C, depending on gasket material
Key features
What the connection brings with it.
- Sterile connection, crevice-free design
- For gases and liquids
- Product-contact surfaces electropolished
- Four connection types available
- Gaskets FDA conform, USP Class VI, TSE-free
- Product-contact parts marked for traceability
Connection types
Four connections, one sealing principle.
The sealing point is identical in every version. What differs is how the two halves are held together — and with it the space required and the effort to open the connection.
Sterile Clamp Union
Two ferrules, one clamp. Opens without tools — right where a line is dismantled often.
Sterile Flange Connection
Bolted flange for permanent installations and higher forces at the joint.
Sterile Large Flange Connection
The same design for large nominal sizes, where bolt forces must be distributed.

Gasket materials
The material decides how far it goes.
The gasket, not the stainless steel, limits where the connection can be used. Five materials cover the range from −200 to +260 °C.
EPDM
−40 bis +150 °C
Standard version
FEP / Silikon
−60 bis +200 °C
Silicone core with FEP jacket
FKM
−20 bis +200 °C
Resistant to oils and fuels
PTFE-Verbund
−200 bis +250 °C
Widest temperature range
FFKM
−10 bis +260 °C
Highest chemical resistance
Applications
Where hygienic design is not optional.
Wherever transfer must stay sterile and a leak costs the batch: in liquid and gas lines of high-purity systems, in pharmaceuticals, biotechnology and food production.
