Water purification tubing connects the corresponding equipment and points of use. Procurement must specify actual outside diameter, wall thickness, material documentation, and connection method.
Selection and compatibility documentation
2-fen and 3-fen are common trade size names. Model dimensions, fitting compatibility, the medium, and allowable temperature and pressure ranges must still be checked. Short names do not replace drawings.
Maintenance and replacement
Route, secure, and inspect tubing according to product and installation instructions. Do not assume an old section of tubing that has been bent remains a reliable connection.
Prepare these four types of information before an inquiry
| Information | Information to provide |
|---|---|
| Existing equipment and components | Complete models, original part numbers, connections, and available documentation |
| Actual treatment task | Raw water or medium information, applications, and downstream requirements |
| Site connections and conditions | Dimensions, installation location, maintenance direction, and allowable operating conditions |
| Procurement and handover scope | Materials, quantities, accessories, maintenance documentation, and evidence requiring further checks |
Common selection questions
Can 2-fen and 3-fen tubing be directly interchanged?
The corresponding fittings and system design must confirm compatibility. Flow, length, and installation conditions also require checking. Adding an adapter alone does not establish suitability.
