Eisele Cleanline: hygienic couplings for the food contact zone
Cleanline is Eisele's hygienic design line: stainless steel couplings with polished surfaces, designed according to the guidelines of the European Hygienic Engineering & Design Group (EHEDG). Intended for the zone where a connection is actually in contact with food or where contamination is unacceptable.
Where an ordinary stainless steel coupling is corrosion-resistant, Cleanline goes a step further: the outer contour is rounded and machined to minimal roughness, and the construction is designed so that cleaning fluid can reach everywhere. Eisele has been a member of EHEDG since 2015.
Applications
- Filling and packaging technology: installations with direct product contact
- Food production: processing lines with daily cleaning
- Beverage industry: filling lines and process installations
- Pharma and medical technology: production environments with strict material requirements
- Cleanroom applications: where cleanability and material origin are specified
Features
Hygienic design: polished surfaces, rounded outer contour and minimal roughness, so no residue adheres.
Optimal cleanability: designed according to EHEDG design guidelines for cleaning in the contact zone.
Full nominal bore: the coupling does not restrict the flow, so you do not sacrifice flow for hygiene.
Bulkhead fittings: hygienic bulkheads provide a safe transition between the hygienic zone and the non-sensitive part of the installation.
All stainless steel: no plastic or coated parts in the contact zone.
PFAS-free: PFAS-free seals (EPDM) and PFOS-free FKM.
Conformity and certification
Cleanline complies with Regulation (EC) 1935/2004 and FDA 21 CFR. The seals are FDA-compliant and available in a PFAS-free version (EPDM) and PFOS-free FKM.
About EHEDG certification: Cleanline is designed according to the EHEDG design guidelines. Within the range, the version with tube size OD6 is EHEDG-certified. If certification is a hard requirement in your specification, please state this in your request and we will confirm in advance which versions meet that requirement.

Matching tubing: ProFood
For the food industry, Eisele supplies ProFood tubing, compliant with Regulation (EC) 1935/2004, Regulation (EC) 10/2011 and FDA 21 CFR. Production follows GMP (EC 2023/2006). The tubing is very flexible and suitable for a wide temperature range.
Frequently asked questions
Is Cleanline EHEDG-gecertificeerd?
Cleanline is designed according to the EHEDG design guidelines. The version with tube size OD6 is EHEDG-certified. The other sizes are designed according to the same guidelines. If certification is a specification requirement, let us know and we will confirm which version meets it.
Which food safety standards does Cleanline meet?
Cleanline complies with Regulation (EC) 1935/2004 and FDA 21 CFR. The matching ProFood tubing also complies with Regulation (EC) 10/2011 and is produced according to GMP (EC 2023/2006).
Are the seals PFAS-free?
PFAS-free versions are available with EPDM seals. The FKM version is PFOS-free. Given the tightened European regulations, we recommend explicitly including this point in your specification.
What is the difference between Cleanline and Inoxline?
Both are made of stainless steel. Inoxline focuses on corrosion resistance and broad industrial use; Cleanline is specifically designed for the direct food contact zone, with polished surfaces and optimal cleanability according to EHEDG guidelines.
What can I use Cleanline for?
The line is suitable for compressed air and cooling water in hygiene-sensitive installations. The hygienic bulkhead fittings also provide a safe transition between the hygienic zone and the rest of the machine.
