Specifications and configuration
Reference — ALFAGOMMA 202AA hose used in V-ZEN clamp-end assembly examples
| Parameter | Documented value / configuration |
|---|---|
| Hose stock identity | 202AA EPDM water suction/delivery hose; pictured assemblies show 202 EVOLUTION brandingConditions: scope: The photo shows several assembled lengths; no unique complete-assembly part number is published |
| Hose construction | EPDM inner and outer layers with textile-cord reinforcement and embedded steel helixConditions: scope: Hose-body material statement; does not establish end-fitting alloy or assembly qualification |
| Listed hose stock working pressure | 10 barConditions: scope: 202AA hose stock, not the pictured clamp-ended assembly or every hose diameter/end fitting combination |
| Pictured end style | Metal sanitary clamp-style ends visible on multiple completed hose piecesConditions: scope: Visual observation only; actual clamp standard, diameter, ferrule alloy and joining method need a drawing |
Manufacturer series reference. Confirm the exact order code, mating parts and stated conditions for the quoted configuration.
Overview
The isolated main visual illustrates one complete EPDM liquid-line assembly with clamp-style metal ends. It was edited from the documented batch photograph, shown in the gallery, and does not identify a finished order code or a fixed available length.
Construction and interfaces
The page identifies ALFAGOMMA 202AA EPDM hose with EPDM inner and outer layers, textile reinforcement and a steel helix. The image shows metal sanitary-clamp-style ends; their alloy, ferrule process and clamp standard are not specified.
Selection
The supplier's embedded 202AA table lists 10 bar for the bare hose stock. Finished-assembly pressure depends on the selected end fittings, attachment method, size and test, so use the lower validated assembly limit for the actual circuit.
Configuration options
Specify the hose bore, finished length, bend route, both clamp interface dimensions, gasket, coolant, cleaning and end orientation. The image shows different physical pieces but does not define a catalog matrix of available lengths or ends.
Application limits
The page mixes 202AA and 223AA references and has a temperature-conversion issue, so no 223AA or temperature value is copied into this entry. Visual clamp identification is not proof of a named hygienic standard or coolant compatibility.
