The A4.12 provides four hydraulic lines in 1/2″ in two twin hoses, with spring return. Its 13 sizes cover 1.2 to 20 m usable length with a maximum flow rate of 40 l/min. This is the dedicated 1/2″ page, separate from the A4 Standard.
A4D296.12.XX: right-hand model, 1/2″ diameter; A4S: left-hand. Suffix XX identifies the hose type to be confirmed.
/VD.Dimensions in millimetres; A = 252 mm and B = 129 mm for every row. Weights without hoses; weight for 700 is not specified. The drawing shows 4 × 3/8″ or 4 × 1/2″: confirm the fittings for the selected version.

For an equipped reel, replace XX with the validated type, for example A4D296.12.B1. For a bare reel, state this explicitly. The mounting drawing shows Ø 11 mm holes on 60 mm square centres, 80 mm overall size; PDF/STEP drawings on request.
The permissible pressure of the supplied assembly must respect the limits of the reel, hose and connections. Specify the fluid, its temperature, the flow rate and working pressure to validate the equipped part number; the pressure rating of the reel alone does not guarantee that of every hose combination.
TU2 catalogue reference data: pressure ratings of the hose alone, in bar. These values are not the guaranteed pressure rating of the equipped reel. The final configuration must respect the limits of all its components; the table below does not establish that every combination is available in every size.
| Internal Ø | Hose type | Pressure rating of hose alone (bar) |
|---|---|---|
| 1/2″ | B1 | 190 |
| 1/2″ | R8 | 245 |
| 1/2″ | T2 | 260 |
| 1/2″ | B2 | 310 |
To replace a reel, send the full part number and a photograph of the nameplate, mounting details, right/left-hand version, working position, fittings and usable length. Request the manual for the exact version before installation or servicing.
Compare the S4 for four separate hoses; for 5/8″ or 3/4″ diameters, see the A4.19. Keep the full part number: the number of lines alone defines neither travel nor connection. See the DEMAC technical catalogues.
Tell us the number of lines, hose diameter, working pressure and flow rate, usable length and the machine to be equipped.
